The conference reported herein was held under the aegis of the National Academy of Sciences-National Research Council with the approval of the Governing Board of the NRC. Such approval indicated that the Governing Board considered that the problem is of national significance, that solution of the problem required scientific or technical competence, and that the resources of NRC were particularly suitable to the conduct of the project. The institutional responsibil- ities of the NRC were then discharged in the follow- ing manner: The members of the conference com- mittee were selected for their individual scholarly competence and judgment, with due consideration for the balance and breadth of disciplines. Responsi- bility for all aspects of this report rests with the com- mittee, except that opinions and conclusions attributed in the report to individuals are not necessarily those of the committee, the Highway Research Board, or the National Research Council. Although the reports of Highway Research Board committees are not submitted for approval to the Academy membership or to the Council of the Acad- emy, each report is reviewed by a second group of appropriately qualified individuals according to pro- cedures established and monitored by the Academy's Report Review Committee. Such reviews are intended to determine, inter alia, whether the major questions and relevant points of view have been addressed and whether the reported findings, conclusions, and rec- ommendations arose from the available data and in- formation Distribution of the report is approved, by the President of the Academy, only after satisfactory completion of this review process.

They describe compute r- dispatching sys- tems that have recently been implemented in their taxicab companies. Wilson and Higonnet further discuss the use of computer-dispatching of demand- responsive vehicles. The decision to publish the conference proceedings was made for several rea- sons. First, they contain the most cur- rent information on demand-responsive transportation systems. Second, the con- ference had an unusual cross section of participants and ideas representing many different organizations concerned with transportation. Third, the experiences gained by those who have implemented demand- responsive systems are valuable for the implementation of similar or new systems. The presentations were made by drivers, owners, and operators of vari- ous implemented systems. Their intent was not to present scholarly papers but rather to explain their systems from their perspectives. One of the principal objectives of the conference was to bring together people from many different ori- entations to focus on an area of common concern. Therefore, there is a wide variation in the approach used for each presentation. An attempt was made dur- ing editing not to destroy the original flavor that each author wanted to convey.

Further, taxi com- panies can act as operators of dial-a-bus systems. A number of shared taxi ser- vices already embody some aspects of dial-a-bus. Even this brief account has demon- strated the inadequacy of existing modes. The inflexibility of rail and bus lines, the high costs of taxis, and the shortcomings of the private automobile—all of these weaknesses argue for an alternative that incorporates the strengths and avoids the pitfalls of conventional transit options.

DIAL-A-BUS IS A DEMAND-RESPONSIVE SOLUTION

The private automobile is the mode over which the user exercises the most direct control. Though it is convenient, parking usually presents a problem, and, where the vehicle is shared by a family, it is not always accessible. Dial-a-bus is an attempt to create a form of public transit that is controlled by its users— transit that is demand responsive. It is for this reason that dial-a-bus can corn- DIAL-A-BUS EXPERIMENT IN BAY RIDGES John A. Bonsall Operational Planner, Ontario Ministry of Transportation and Communications

Question: When the weather is bad and there is an extra heavy load of people so that the driver cannot make his rounds in time to catch the train, what happens? Answer: The dispatcher has the final say in controlling the buses, and he can, in those circumstances, reallocate his own boundary. For instance, a zone 1 bus might pick up some people in zone 2 if there is a heavy demand. If there is a heavy demand throughout the community, we do have a standby bus that we can use if necessary.

The in-between areas where there is high demand from low-income groups will have both fixed-route service and telebus be- cause the demand is high enough to pro- vide both. People in those areas will have a choice of fixed-route service or deluxe service. Anyone in those areas unable to walk to a bus stop will get a telebus pass paid for by welfare funds. We think this is the way to go.

Question: What is the bus-driverwage rate? Answer: Driver wage rate is among the highest in the country—about $4.00 per hour. B-LINE DIAL-A-BUS SYSTEM IN BATAVIA

are going to be quite valuable not only for travel on the dial-a-bus project but for overall travel in the neighborhood.

INFORMAL DISCUSSION

Question: What has been the response to the dial-a-ride? Answer: The response from the neighborhood in general has been good. In fact, a private firm queried residents, and our PrOject rated No. 1 of 33 Model Cities projects that included housing, health care, and everything else. The reason for the good response is that the service is very visible to the residents. We have had some problems with break- downs, and some waiting times are longer than we like; but, in general, I think the residents view this service very positively.

Question: How large is the service area? Answer: The population is 37,000.

Question: What is your level of service? Answer: The scheduled headways were running 4 every 25 minutes. Our average waiting time is about 25 minutes, and our average driving time is about 25 minutes. This is based on preliminary data and would have to be verified.

Question: Might a taxicab company operate the service? Answer: Well, it might. We are do- ing it the way we are because of the taxi franchise and the bus company franchise. At one time, we tried to use taxicabs because they have more flexibility, but we got into real tough political and legal problems and wound up with this kind of an operation.

as in the United States. Does the lack of telephones give you any problems? Answer: It is a problem. The average telephone ownership in the United King- dom is about 40 percent of the households. Some of the areas we are servicing, of course, are significantly higher than that. In some of the better residential areas it is nearly 100 percent. Because there are no telephones, we are cutting off, in ef- fect, a part of the population, or at least making it difficult for them. One possible way around this is to make provision for people to book well in advance; the other way is, of course, to do what we are do- ing with the Kingsmoor, and that is to in- troduce some element of fixed routing and fixed scheduling. Telephone ownership is increasing at the rate of, I think, 6 or 8 percent per year so that one must realis- tically look at dial-a-ride as a service that, if it is going to succeed, will only succeed in perhaps 5 or 10 years. For the moment, we have to accept that we are, in fact, cutting off some of the people.

Question: Will the systems cover costs out of the fare box? Answer: I think you will have to ask me that in about 3 months. I really do not know yet. The general principle that is being followed in Abingdon is that service ought to pay for its operating costs out of the fare box, but I think the bus company, in this case, would expect that it would not have to cover its capital costs as well. Whether it will cover its operating costs I do not know. It has operated only 1 day so far, to my knowledge, and it did not cover its operating costs on its first day.

The overall funding for this demon- stration—the $1.7 million—assumes no revenues. All revenues are put into a separate account and returned to the gov- ernment separately. Therefore, even if we did not take in a dollar, we are still fully funded. That is one reason why we can have the service level somewhat ahead of what the demand is. And we hope to keep it that way.

INITIAL OPERATING RESULTS

Ridership

Figure 1 shows weekly ride rship dur- ing the 11-week period since service began on May 15. DAR has served 27,435 pas- sengers during this period. Figure 2 shows average ridership on weekdays, Saturdays, and Sundays. The average number of weekday riders was 495 during this period; the peak was 580 passengers on June 23. The greatest number of riders was generally carried on Fridays, and the lowest number was carried on Sundays. Saturday ridership exceeded the average for weekdays dur- ing the first week of operation and again during the week ending June 11, when it reached a daily peak of. 402 passengers. Since that time, Saturday ridership has Figure 2. Average ridership on weekdays. leveled off somewhat, with a mean of 297 Saturdays. and Sundays (May 21 to July 28, passengers per day. Sunday ridership 1972). during the 11-week period has remained relatively constant, increasing from a low of 92 passengers per day during the first week of operation to a mean of 136 passengers per day for the period from June 11 to July 30. The hourly ridership on a typical week- day is shown in Figure 3. (Datashownin Figures 3 through 9 were obtained on 5 weekdays: June 8 and 16 and July 10, 18, and 26.) Trips between 9 a.m. and 4p.m. account for 45 percent of the daily total. About 20 percent of daily trips are made between 4 and 7 p.m., and about 7 percent are made between 7 and 9 a.m. The last percentage may be low because Medville 48

Vehicle productivity, however, should not be viewed as the only measure of system performance. For a given demand rate, a large num-. ber of vehicles in operation will result in both a relatively low vehicle productivity and a high quality of service because waiting and riding times will be short. As the number of operating vehicles is reduced, productivity will increase, be- cause each vehicle will carry more pas- sengers, and quality of service will de- crease, because there will be fewer ve- hicles to service customer requests.

Quality of Service

The quality of service greatly influ- ences the number of riders attracted to dial-a-ride.

Table 7 gives average wait and ride times and average pickup time deviations by period of the day for the days sampled. As the day progresses and ridership in- creases, the average wait and ride times also increase. As vehicle productivity (requests per vehicle per hour) increases, so do the average wait and ride times be- cause each vehicle will have more pas- sengers to pick up and drop off. The relation between vehicle produc- tivity and unit-ride time is shown in Fig- ure 9. The data show that, as the day I I, progresses and ridership increases, both vehicle productivity and customer wait and ride times also increase.

deal of information concerning the atti- tudes toward and preferences of potential DAR users. Through this survey, resi- dents of the service area had a voice in the selection of system operational param- eters. The 60-cent cash fare, reduced rates for senior citizens and for those pur- chasing books of tickets, service to local shopping areas, 15-min average wait time and 10-min average ride time are all based on statements of survey respon- dents regarding dial-a-ride attributes that they preferred or felt were reason- able. As far as possible, the service has been designed to meet the needs of those whom it serves. DIAL-A-RIDE PROJECT IN ANN ARBOR: DESCRIPTION AND OPERATION

Thomas Urbanilc, II Dial-A-Ride Project Coordinator, Ann Arbor Department of Traffic Engineering and Transportation

The purpose of the Ann Arbor dial- a- Figure 1. Service area. ride project is to test the market re- sponse and economic viability of door-to- door, dynamically routed and scheduled public transportation in a Michigan com- munity. The project is sponsored by the Michigan Department of Commerce, Bureau of Transportation, and the Ann Arbor Transportation Authority (AATA). The Transportation Research and Plan- ning Office of the Ford Motor Company is technical consultant. This report describes the project and gives a summary of the operation from September 20, 1971, to February 29, 1972. The information was assembled by the consultant and project staff.

Each datum is an observation of waiting, riding, and total travel time for a specific pickup and delivery address, independent of multiple riders; i.e., service times for 2 persons traveling together are recorded once, not twice.

Several operating dial-a-ride systems have demonstrated conclusively that there is a better way of moving people in these low-density situations than with conven- tionally operated buses.

INFORMAL DISCUSSION

Question: Are there other sources of revenue for dial-a-ride besides the fare box? Answer: Yes. Some of these sources are being developed in Batavia.

Question: How important is public at- titude in general in convincing politicians to spend public money for a dial-a-ride system? Answer: Sociological researchers tell us that, if a community is oriented in a public-spirited way toward one.thing, it will tend to be oriented that way toward all things. If a community supports day- care centers, it will probably also sup- port public transportation. There is a coalition in Ann Arbor right now between what I call the bicycle freaks and the transit freaks. They have motivated a large bloc of the community to stop addi- tional road improvements in this current budget year. This is a fantastic develop- ment. It suggests how important public attitude is and that the people in the com- munity must want something before poli- ticians cause it to happen. If the people are indifferent, forget it.

INFORMAL DISCUSSION

Question: Who supported the surveys you described? Answer; The Warren survey was supported solely by General Motors, and the Columbia survey was supported by the University of Minnesota.

Question: Did the responses of the Warren survey nonusers correlate with those of the Columbia survey? Answer: That is a subject for future research. We have not had a chance to analyze those data, but we certainly intend to. COMPUTERS, TAXIS, AND GRASS ROOTS TRANSPORTATION

The key questions for the future are, How much will a computer improve ser- vice provided by a transportation system? and How much will it increase produc- tivity? These questions are now largely unanswered. Looking at the overall costs of dial-a-ride, we see that perhaps 70 percent of the costs relate to the drivers and vehicles and that the remaining 30 percent relate to control and dispatching. If productivity of the transportation ser- vice can be increased by, say, 25 percent as a result of using computer dispatching, then it would be reasonable to increase control costs by as much as 55 percent because of the greater weight vehicle ISSUES AND POLICY QUESTIONS CONFRONTING PUBLIC TRANSPORTATION

James A. Scott, Highway Research Board staff THE National Academy of Sciences is a private, honorary organization of more than 800 scientists and engineers elected on the bascs of outstanding contributions to knowledge. Established by a congressional act of incorporation signed by Abraham Lincoln on March 3, 1863, and supported by private and public funds, the Academy works to further science and its use for the general welfare by bringing together the most qualified indi- viduals to deal with scientific and technological problems of broad significance. Under the terms of its congressional charter, the Academy is also called upon to act as an official—yet independent—adviser to the federal government in any matter of science and technology. This provision accounts for the close ties that have always existed be- tween the Academy and the government, although the Academy is not a governmental agency and its activities are not limited to those on behalf of the government. The National Academy of Engineering was established on December 5, 1964. On that date the Council of the National Academy of Sciences, under the authority of its act of incorporation, adopted articles of organization bringing the National Academy of Engi- neering into being, independent and autonomous in its organization and the election of its members, and closely coordinated with the National Academy of Sciences in its ad- visory activities. The two Academies join in the furtherance of science and engineering and share the responsibility of advising the federal government, upon request, on any sub- ject of science or technology. The National Research Council was organized as an agency of the National Academy of Sciences in 1916, at the request of President Wilson, to provide a broader participation by American scientists and engineers in the work of the Academy in service to science and the nation. Its members, who receive their appointments from the President of the National Academy of Sciences, are drawn from academic, industrial, and government organizations throughout the country. The National Research Council serves both Academies in the discharge of their responsibilities. Supported by private and public contributions, grants, and contracts and by voluntary contributions of time and effort by several thousand of the nation's leading scientists and engineers, the Academies and their Research Council thus work to serve the national interest, to foster the sound develop- ment of science and engineering, and to promote their effective application for the bene- fit of society. The Division of Engineering is one of the eight major divisions into which the National Research Council is organized for the conduct of its work. Its membership includes rep- resentatives of the nation's leading technical societies as well as a number of members-at- large. Its Chairman is appointed by the Council of the Academy of Sciences upon nomination by the Council of the Academy of Engineering. The Highway Research Board is an agency of the Division of Engineering. The Board was established November 11, 1920, under the auspices of the National Research Council as a cooperative organization of the highway technologists of America. The pur- pose of the Board is to advance knowledge of the nature and performance of transporta- tion systems through the stimulation of research and dissemination of information de- rived therefrom. It is supported in this effort by the state highway departments, the U.S. Department of Transportation, and many other organizations interested in the develop- ment of transportation.
