A model which will provide a tool in evaluating advanced low-emission automotive power systems, and a basis for decisions relating to further development of candidate power systems is presented. The technique is quan- titative and readily adaptable to the stage of a candidate's development. It relies primarily on engineering measurements and provides con- sistent repeatable results. It allows the use of expert value judgments as a valid part of the evaluation process. The parameters which, when measured, will provide the information needed to describe and adequately evaluate the candidate are listed, and the measurement scales and the rationale for the parameter selection are provided.. The cost and economic factors critical to the evaluation of candidates are discussed. The analytical formulation of the model is addressed.

The purpose was to assess the practicality of a transmission for use in a heat engine/flywheel propulsion system to reduce emissions. The system was to be suitable for incorporation into a full size family car' automobile. The different possible link types (mechanical, hydrostatic, and hydromechanical) between the engine, flywheel, and vehicle wheels were analyzed. Many transmission schematics were in- vestigated, and several combinations were selected for further evaluation resulting in the final recommended configuration. Controls were selected and analyzed using a digital dynamic simulation computer program and an analog computer simulation. System per- formance, stability and driveability were detenned Cost estimates were made for the selected configuration using comparative data, vendor quotations and in-house estimates. Comparisons with a conventional three speed automatic transmission were made. A hydromechanical transmission configuration with interdependent links between the flywheel, engine, and wheels was the resultant selection. The flywheel/transmission was configured for a tran-axle installation, which was considered optimum.

An analytical and experimental investigation of articulated vehicle handling was conducted to develop the facility for prediction of the dynam- ic behavior of single- and double-articulated vehicles during commonly encountered road and speed-maneuvers and subject to aerodynamic influences. To this end, an experi- mentally validated digital simulation model, AVDS II, was developed which uses the inverse trajectory method whereby the steering de- mands, braking demands, and the vehicle response are computed for given tire charac- teristics and prescribed tractor trajectory. The AVDS II was used to conduct a parameter varia- tion study on the factors that affect articulated vehicle handling.

The first one is a simulation model, called FREEQ, which can be employed to generate all necessary information such as total travel time, individual average travel time on the freeway, provided that the demand pattern and the physical configuration of the freeway are known. Based upon these results, an optimiza- tion model is used to search for the best loca- tions of the service facilities so that the total delay time caused by the accident or incident or the response time of the service unit is minimized.

The systems study effort has been directed toward the verification and refinement of the conclusions reached in a previous study, which indicated that the fly wheel hybrid drive con- cept might be a technically feasible way to power a full size automobile. The present study makes use of more detailed input information on engine emissions on transmission charac- teristics. These data are augmented by detailed flywheel technology studies and test results to provide the background for more precise con- clusions regarding the flywheel drive concept. The results do indicate that the flywheel bybrid drive concept is a technically feasible propul- sion system for a full size automobile. The re- port describes the work done to accomplish the following goals: advance the development of flywheel systems technology including the development of final designs on conformal housings, bearings, seals, and evacuation systems; demonstrate positive flywheel energy containment in burst tests of flywheels; formu- late safety analyses, using fault-tree and gross- hazard methodologies, produce engine- mapping project data to permit calculation of engine emission data resulting from flywheel drive operations.

The program has application to a broad class of transportation systems and is modular in design. It is based on the finite ele- ment' or building block' method in which a complex dynamic system is made up of a number of components. The equations of mo- tion of each of these components is known and combined to form the complete equations of motion of the system The equations of motion are then integrated numerically to give the response of the system to variables such as guideway roughness, span, etc. The program is equipped with several output options.

The Intercity Transportation Effectiveness - Ac- cess/Assignment Model is a planning tool designed to evaluate the alternatives available for increasing the capacity of groundside pas- senger handling facilities to accomodate the expected increase in air travel, specifically the expansion of existing airports, the construction of new airports, and the construction of off-site or satellite passenger processing facilities. The model is capable of representing specific re- gions, including multicity, multi-airport situa- tions. Proposed system of facilities can be tested easily at little cost. The assignment of air passengers to facilities in a proposed system is designed to reach an equilibrium between the facility supply (represented by time im- pedances) and the passengers using the facili- ty. The capital costs of the system are com- puted on a daily basis, enabling a comparison with reductions in the passengers' perceived time costs.

Three objectives of the research were to: (1) develop a method for analyzing braced excava- tions based on the principles of soil mechanics and the finite element technique, (2) provide in- sight into the undrained behavior of braced ex- cavations in clay, and (3) predict the per- formance of two instrumented sections of a braced excavation. The demonstration was un- dertaken in a section of cut-and-cover subway constructed by the Massachusetts Bay Trans- portation Authority. The research was intended to illuminate design and engineering con- siderations with reference to load factors ap- plied to brace sheeting, the transfer of loads to the bracing system, ground movements and changes in water hydrology due to construc- tion, and other questions. The finite element technique was used to develop a unique com- puter program for predicting movements in the soil mass and the retaining wall, stresses on the wall, and loads in the struts.

The problem of designing a transportation net- work that will best satisfy expected demand for travel among a given set of centers of activity is formulated by identifying for each origin- destination pair, called a commodity of the transportation network, all the alternative routes for travel that meet prespecified criteria and which constitute the set of feasible paths. Modal choice is assumed to be a function of travel time and consequently the model generates expected demands for travel, over al- ternative routes of different length, from a probability distribution function of travel time associated with each origin-destination pair.

However, prior to any major over-haul of NDR computer programs an in- depth study of what the role of the NDR should be in the future of nationwide driver records communications is deemed essential. This study identified four alternatives available to the NDR, however only one will meet the needs and requests of state driver licensing adminis- trators. This alternative requires an alteration in the NDR in terms of data content, category of users, and type of service. Requested is an on- line pointer/index system that would aid driver licensing officials in locating records on drivers who have: Medical/physical limitations; records of violation that require monitoring or recent suspensions; revocations; denials; withdrawals or cancellations in other jurisdic- tions.

A cost function which takes into ac- count the sum of maintenance and associated costs has been developed. The total cost con- sists of the cost of periodical preventive main- tenance and the cost of failures and unscheduled repairs. The cost is expressed in terms of various cost elements and the proba- bilities of failure for different systems on the bus. A computer method is used to derive the least cost maintenance schedule.

Existing manual procedures for material haul tickets when payments are by weight involve a considerable amount of manual checking, arithmetic calculations and ticket accountabili- ty. The availability of small mini-computers and appropriate input and output devices allowed for the development of a portable, automated data acquisition system which is capable of capturing the data at its source. All of the func- tions of ticket generation, ticket accountability, material summary reports and checking are ac- complished with the system. An additional im- portant feature is that the hardware is small enough to be transported from project to pro- ject Due to its interactive mode of operation, a technician can be trained to use the system in approximately one hour While cost effective- ness of operating this system depends on the size of the hauling operation and the amount of checking required, the overall benefits of the system are derived from accurate, flexible documentation and the release of skilled technicians for other work. Since the data is captured at its source in a computer environ- ment, remote transmission to a central material control system would minimize subsequent material accounting procedures involved in contractor payments and materials testing.

The feasibility of setting aside one lane for the exclusive use of bus and car pools on New Jer- sey Route 3 was performed. The PRIFRE Model, a computer model which determines traffic conditions for normal and priority operations, was calibrated to represent Route 3. Numerous configurations of bus and car pool lanes were identified, and five priority configurations were modeled for eastbound traffic. Three other pri- ority configurations were modeled for east- bound traffic. Three other priority configura- tions were modeled for westbound traffic. A major criteria in the analysis is the occupancy shifts required in terms of cumulative pas- senger hours, travel time, vehicle miles traveled, and traffic operations. A benefit-cost analysis was performed including considera- tion to user and system costs. The report con- tains a recommendation that the state of New Jersey implement a bus and car pool lane in each direction according to specified criteria.

In particular it deals with noise and vibra- tion control for urban rail transit track and elevated noise and vibration control for urban rail transit track and elevated structures. The model allows for the prediction of both the vibration transmission between elements of the structure and the resulting noise radiation from each major structural element, in terms of design parameters for the different elements. Thus the potential effectiveness of various al- ternative methods for noise control can be eval- uated. Results of a field study of three different 37 types of elevated structure on the MBTA Rapid Transit System are also summarized. These results support the validity of the prediction model The engineering application of the pre- diction model is discussed in another report.

The study objective was to determine the amount of heat removed from rapid transit tun- nels by adding wayside resistors which would absorb braking energy that could not be ab- sorbed by normal regeneration. In addition. preliminary design and cost data for the instal- lation of the wayside resistors was to be pro- vided. As the study progressed it was found that the addition of the wayside receptive devices provided a very marginal improvement over normal regeneration, and a substitution in the direction of the study made; the effect of im- proving the regenerative capability of the trains was measured rather than completion of the design for the wayside resistors.

The processing of system performance data is the topic of this report. The Haddonfield system was scheduled manually from the start of the demonstration in February 1972 until February 1974. During the latter part of this period, the automated system was the primary scheduling system. The procedures used in col- lecting and processing data from the manual scheduling system are described. Also discussed are manual system data files and tabulations. The computer programs that process automated system data and the auto- mated system tabulations are presented.

Four basic evaluation models are identified for com- parative analysis. The focus of the analysis is on the theoretical soundness of the models and on the sensitivities of the models with respect to the number of alternatives encountered, to the distribution of outcome states, and to the addi- tion or the reduction of the number of alterna- tives from the original set.

The NNS zone system was developed for use in the analysis of national modal freight flows. The BEA area system was primarily developed for the alloca- tion of national economic data to regions of the United States. Assuming flows of commodities are known among the NNS zones, the NNS zone to BEA area mapping enables the determina- tion of flows among the BEA areas. The report presents zone to area mapping which utilizes 1970 economic data as the basis when an NNS zone overlaps more than one BEA area. It also presents computer programs that could be used to generate a mapping using economic data from some other year. PB-251 530/2CP PC A10/MF A01 ARCTEC, Inc., Columbia, Md.

In fixed guideway transit with established sta- tion stops, the propulsion energy can be reduced by grading the guideway downward on leaving the station (using gravity to assist in the acceleration) and grading upward on arrival at the next station (again using gravity, but this time to assist in the braking). A computerized conceptual cost model has been developed in- corporating parameters relating to required elevated structures and required dynamical considerations. The increase in total cost required to construct a station stop at a given elevation above the guideway level between stops is calculated by the computer program to be compared with the resultant decrease in energy consumed in acceleration and decelera- tion. Because today's costs are extremely un- certain, unit costs are input by the user to deter- mine the increased construction and operating costs and the resultant energy savings. The program outputs suggestions for structural design and associated cost data. PB-254 226/4CP PC A09/MF A01 Polytechnic Inst of New York, Brooklyn. Dept. of Transportation Planning and Engineering.

Identifiers: FORTRAN 4 programming lan- guage. The report represents the completion of a pro- ject which deals with the economics of rapid transit train control. Information dealing with rapid transit control systems from all parts of the world is used for the development of a com- puter program to analyze costs of an automatic vs. manual train control system. The Train Con- trol Analysis Program (TCAP) utilizes actual data from a rapid transit operator. This data can be from an existing manual system which is considering automation, or it may be a system in the planning phases, which is trying to deter- mine the proper transit control to utilize. The program operates in a time sharing mode so that it is very convenient to change certain input parameters and observe the correspond- ing analysis immediately. This program can be used to determine what the above benefits may cost in relation to a less sophisticated system. The results of this analysis may be used in the decision making process of selecting an adequate control system. Color illustrations reproduced in black and white.

The study has examined the implications of dramatic increases in transit patronage on system structure and performance. Models were developed to examine the cost and service attributes of a variety of system components, including express bus, exclusive lane opera- tion, subscription service, dial-a-ride, and several route-based feeder options. These models were applied in a regional context over a range of patronage assumptions to evaluate both the individual components and the synergisms resulting from various service com- binations. The analysis has provided insights into the structure of integrated transit systems and the expansion of these systems to serve in- creasing shares of urban travel.

The report describes the development, compu- terization, and application of an analytical procedure for entry control at freeway ramps Two types of control strategies are developed: control on a passenger basis and control on a vehicle basis. The analytical procedure encom- passes two models. The first is a simulation 45 model which is deterministic and macroscopic, that predicts the freeway traffic performance as a function of freeway design and allowable ramp flows. The second is a decision model, which has a linear programming formulation, that selects a control strategy meeting the ob- jectives and constraints. The simulation model was validated under field conditions, and the predicted traffic performance compares very favorably to actual, measured traffic per- formance. The two models were integrated and computerized, and the composite model was applied to a number of sites to demonstrate its applications and to provide some results for possible implementation.

The hybrid computer simulation for vehicle handling studies has been in use for four years and has been validated for a large class of two axle vehicles. The following suspensions can be simulated: (1) four wheel independent, (2) independent front and solid rear axle, (3) solid front and rear axles, and (4) any front suspen- sions with dual tires on a solid rear axle. Model validation was accomplished using parametric data representative of a 1974 Chevrolet NOVA, 1974 VW Campmobile, 1974 White Tractor and various other automobiles and trucks. Braking, steering and combinations of braking and steering were input to the simulated mathe- matical model for validation and the simulation time histories were then compared to full scale test data. This hybrid vehicle handling program can be used for general studies of vehicle dynamics.

Identifiers: BASIC programming language, ANSYS computer program. The feasibility study on the use of acoustic signatures for detection of flaws in railway wheels was conducted with the ultimate objec- tive of development of an intrack device for moving cars. Determinations of the natural modes of vibrating wheels under various condi- tions are reported. Differences in acoustic signatures are found between good and cracked wheels, including spectral changes and variations in the time decay of sound. Vari- ous sounds occurring in normal railroad prac- tice, such as rolling noise on welded rail and over joints and retarder screech were in- vestigated. It was concluded that special pur- pose impacters will have to be used for a ser- vicable device. Pattern recognition techniques were used for selecting good and bad wheels with a computerized processing scheme. A laboratory demonstration system has been con- structed and found to be 85% reliable when system malfunctions are discounted. PB-263 466/5CP PC A06/MF A01 Michigan Univ., Ann Arbor.

The project involved development of UTCS time-of-day signal patterns that give preference to buses operating in Sections I and III of the Washington, DC. UTCS traffic control area. Section I is a heavily traveled east-west arterial; Section III is a grid-like network just north and west of the White House, extending to Washington Circle. The overall objective of this work was to demonstrate the feasibility of preferential treatment for buses when using fixed time signalization. This work included data collection and preparation, signal pattern generation and evaluation, and the conversion of selected signal patterns into a format com- patible with signal controllers in Sections I and III. Signal patterns were generated using TRANSYT/5, a software package developed by the British Road Research Laboratory. This ver- sion of TRANSYT includes a bus traffic model, and an option that gives preferential treatment to buses. PB-264 054/8CP PC A13/MF A01 De Leuw, Cather and Co., Houston, Tex.

The most sensitive input parameters to Ozone production are initial concentrations, reaction rate constants, and inversion base height. The ratio of Reactive Hydrocarbons to Nitric Oxide emissions are far more important in determining Ozone production than the ac- tual magnitudes for emissions. The DIFKIN model is most applicable to projects that result in changes in emissions in a few adjacent grid cells rather than widespread changes in emis- sions over an air basin. Five or more trajectories should be used to determine air quality impacts of a particular project. PB-268 870/3CP PC A04/MF A01 National Bureau of Economic Research, Inc., Cambridge, Mass.

Bus detection is based on ILD signal processing (classifier) techniques, thereby eliminating need for any modifications or additions to the bus. Passive bus detection hardware includes special ILD electronics, a high-speed programmable processor, and a microprocessor. Using the same microprocessor, plus programming panel, stored programs, and switching and safety units, the system design is sufficient to exercise bus priority control at urban intersec- tions containing up to 23 signal circuits and 16 ILD transducers. In addition, the system has capability of commanding the traffic signals in either one of three fixed timing patterns, selected at the system by the traffic engineer or controlled by a loop master.

The Metropolitan Accessibility Program (MAP) is a computerized tool that facilitates analyses of transportation access to employment, com- mercial activities, hospitals, and other desired destination opportunities. This program is capable of producing output records that are interpreted by a special plotting program, MAPLOT. MAPLOT is capable of producing graphic displays of spatial variations in accessi- bility levels throughout an urban area, sector, or corridor. The MAP program and all sub- sequent modifications, including the plotting features, is housed within the U.T.P.S. Program, UMODEL. In this report the computer program, MAP, is presented through various User's materials including program documentation and five illustrative case study applications. The five case studies have been developed to aid the programmer in applying MAP and MAPLOT. This report is designed specifically as a User's guide to MAP and should be read in conjunc- tion with the companion report which explains and illustrates the theory and methodology of transportation accessibility studies: Accessibility Applications in Urban Transporta- tion,' by Popper and Connelly (UMTA-VA-11- 0002-77-2).

None of the non-vehicle textural and friction measures correlated well with vehicle performance. However, the vehicle performance was relatively insensitive to pave- ment properties on dry, stable surfaces. The peak coefficient of friction' with partial braking using a tire tester was also insensitive to pave- ment differences. Surfaces that produced some differences in vehicle performance also produced relatively large differences in the locked-wheel coefficient of friction' obtained with a standard skid measurement system. On the pavements used, if the locked-wheel coeffi- cient showed no significant difference between pavements, the vehicle performance measures also showed no significant difference.

Identifiers: Computer applications, HFCCV computer program, HFRES computer pro- grams. Two methods are available for determining control parameters on automated canals. These are the transient-response method and the frequency-response method. Since a typical canal system is influenced predominantly by transient inputs, the transient-response method has been extensively used in the analysis of au- tomated canal systems. The main advantage of the frequency-response method is that the ef- fects of varying the various control parameters can be readily visualized and evaluated. The presently used transient-response method and parameter selection are reviewed. The basic concepts of the frequency-response method are presented and their application to an auto- mated reach is illustrated with an example. Two computer programs are given which can be used to determine canal response charac- teristics. The state-of-the-art in process control has progressed sufficiently so that both the transient-response and frequency-response methods of analysis can be used in a comple- mentary fashion. Employment of only one method in the design of automated systems is, in general, wasteful of both computer time and engineering effort.

Freeway ramp control systems are used to con- trol the flow of vehicles onto the freeway and, thereby, maintain the freeway operations at an acceptable level of service. A green band mov- ing-merge system displays along the on-ramp, information to the ramp drivers to help them identify gaps and merge easily into the freeway flow. The first test and evaluation of the green band concept was undertaken in Woburn, Mas- sachusetts in 1970. The report describes vari- ous traffic operation improvements made to the Woburn green band computer control system. System software changes have been made to minimize the loss of green bands, to stabilize the ends of the moving green bands, and to segment long green bands into shorter, more useable bands Improvements are also described (1) for preventing the unnecessary surge of ramp vehicles to the merge area when the green band system changes modes, and (2) for making during the stopped mode the system more responsive to ramp and merge area ob- structions.

Identifiers: PASSER 3 computer program, Fixed time traffic signals. Diamond interchanges. The report describes the user's manual for PASSER III, a practical computer program developed to assist the traffic engineer in deter- mining optimal traffic signal timings for pretimed or traffic-responsive, fixed-sequence signalized diamond interchanges. The program is applicable to isolated interchanges as well as to a series of interchanges through which progression is desired along the frontage roads. In addition, design engineers may use PASSER III to evaluate the effectiveness of proposed interchange design alternatives. PASSER III can evaluate any signal timing plan that might exist at a signalized diamond in- terchange. The program also determines the level of service for each phase at the intersec- tions which make up a diamond interchange. PASSER III provides all data required to imple- ment the signal timing plan it calculates. Two typical example programs, an isolated in- terchange and a frontage road progressive system, were coded and executed by PASSER III. The completed input data card coding forms and the program output, including time-space diagrams for the progression solution, are con- tained in the report.

In order to examine the feasibility of an intercity freight pipeline, it was necessary to develop cost equations for various competing transpor- tation modes. This volume presents cost esti- mating equations for rail carload, trailer-on- flatcar, truck, and freight pipeline. Section A presents mathematical equations which ap- proximate the fully allocated and variable costs contained in the Interstate Commerce Commis- sion (ICC) cost tables for rail carload, trailer-on- flatcar (TOFC) and truck common carrier inter- city freight movements. These equations were developed to enable the user to approximate the ICC costs quickly and easily. They should find use in initial studies of costs where exact values are not needed, such as in consideration of rate changes, studies of profitability, and in general inter-modal comparisons. Section B discusses the development of a set of engineer- ing cost equations for pneumo-capsule pipeline. The development was based on an analysis of system components and can readily be extended to other types of pipeline. The model was developed for the purpose of a feasi- bility study. It employs a limited number of generalized parameters and its use is recom- mended when sufficient detailed and specific engineering information is lacking.

Identifiers: Bus priority systems, Traffic flow, BUS TRANSYT computer program, Glasgow(England). BUS TRANSYT is a computer program which calculates traffic signal timings that give buses priority in a network of linked fixed-time signals. Buses are modelled separately from other traffic; they follow fixed routes through the network and stop at bus stops. Allowance is made for the variation in running speeds and in the stopped time at bus stops. Buses are given priority by weighting their delay more than the delay to other vehicles when the signal timings are optimized. Approximately two-thirds of the bus benefit comes from optimizing the offsets and one-third from optimizing the green dura- tions. The program is insensitive to errors in the data on bus speeds and stopped time at bus stops. For a full scale test in Glasgow's 95 inter- section network, bus speeds were estimated from 1 man-days's observations and the stopped times at all the bus stops were esti- mated by surveying a sample of 21 stops. The test showed an 8 per cent increase in bus jour- ney speeds over the working day. Delay to other vehicles on bus routes was reduced by 5 per cent but delay off bus routes was increased by 10-20 per cent. Overall delay to other vehicles showed no significant change.
