      <title>THE METRO FLYER. A SUBURBAN BUS SERVICE TO DOWNTOWN, TOWSON AREA, BALTIMORE COUNTY, BALTIMORE CITY, MARYLAND</title>
      <link>https://trid.trb.org/View/131643</link>
      <description><![CDATA[AN INVESTIGATION WAS CONDUCTED INTO THE PRACTICABILITY OF PROVIDING A SURBURBAN, LOW DENSITY, HIGH INCOME RESIDENTIAL AREA WITH EXPRESS BUS SERVICE TO THE DOWNTOWN SHOPPING, RECREATIONAL, AND EMPLOYMENT CENTER. THE TOWNSON, MARYLAND RESIDENTIAL AREA AND ITS SEVERAL ADJACENT SUBURBAN AREAS (COMBINED POPULATION IN EXCESS OF 19,000) WERE PROVIDED WITH MODERN, AIR-CONDITIONED EXPRESS BUS SERVICE TO THE CENTRAL BUSINESS DISTRICT OF BALTIMORE CITY, USING LIMITED ACCESS HIGHWAYS FOR APPROXIMATELY 72% OF THE ONE-WAY TRIP. SERVICE WAS COORDINATED WITH THE PRINCIPAL HOURS OF EMPLOYMENT, AND TIMELY TRIPS WERE PROVIDED FOR SHOPPERS. INCLUDED IN THE PROJECT WERE PROVISIONS FOR FREE PARKING FACILITIES, AN ADEQUATE PROMOTIONAL CAMPAIGN AND A DATA COLLECTION PROGRAM THAT WOULD YIELD INFORMATION OF VALUE TO OTHER COMMUNITIES COMTEMPLATING SIMILAR EXPRESS BUS SERVICE PROGRAMS. THE PROJECT BUS SERVICE OPERATED AS A DEMONSTRATION PROGRAM FOR ONE YEAR. DURING THIS PERIOD, PASSENGER USAGE INCREASED BY 193% OVER THE FIRST MONTH OF OPERATION; AND AT THE CLOSE OF THE PROJECT PERIOD, THE METRO FLYER WAS TRANSPORTING AN AVERAGE OF 496 PASSENGERS PER DAY. THE GREAT MAJORITY OF TRANSIT TRIPS WERE PEAK HOUR, WORK-ORIENTED TRIPS. THE SERVICE WAS CONTINUED, WITH MINOR MODIFICATIONS, BY THE PRIVATE CARRIER AFTER THE CLOSE OF THE EXPERIMENT - AT A PROFIT TO THE CARRIER. /AUTHOR/]]></description>

      <title>ASSESSMENT OF SERVICE REQUIREMENTS AND DESIGN CHARACTERISTICS OF PRESENT AND FUTURE PARATRANSIT VEHICLES</title>
      <link>https://trid.trb.org/View/50604</link>
      <description><![CDATA[The objective of this research project is to provide an assessment of present and future paratransit vehicles, their design characteristics and service requirements from the viewpoint of the passenger, the community, and the driver. This assessment includes comfort, safety, and assessibility of all occupants with particular attention to the special driver problems associated with paratransit service; it focuses on the problems of the elderly and handicapped; and it identifies relevant aspects of the operating environment, namely, pedestrian safety.  Shortcomings of vehicles now in service and new protoype vehicles are identified, and strategies are described to remedy them with minor and low cost modifications.  The scope of this study includes vehicles designed for the Museum of Modern Art (MOMA) Taxi Project, including two paratransit vehicles designed to specifications of UMTA.]]></description>

      <title>PROTOTYPE PARATRANSIT VEHICLE AS DESIGNED BY STEAM POWER SYSTEMS, INC</title>
      <link>https://trid.trb.org/View/82607</link>
      <description><![CDATA[The report discusses a prototype low pollution paratransit vehicle (PTV) designed and constructed for evaluation by the U.S.  Department of Transportation.  Special features of this PTV include a large comfortable interior which would accommodate five passengers, an automated door and ramp system that would provide convenient ingress/egress for a wheelchair passenger, and low pollution Rankine cycle (steam) engine.  This tyep of vehicle aims to provide transportation for the inform, handicapped, and elderly in erither a DIal-A-Ride, jitney, or taxicab service.  The PTV was completed, acceptance tested, and delivered to the U.S. Department of Transportation in June 1976.  The vehicle was displayed as part of a taxi design exhibition (summer 1976) at the Museum of Modern Art in New York City.  Following the exhibition, the PTV was scheduled for dynamic testing by an independent contractor.  This report concludes that the steam engine propulsion system has the potential for low exhaust emissions, but needs considerable improvement in both efficiency and reliability before it is ready for installation in motor vehicles.]]></description>

      <title>DUAL MODE PLANNING CASE STUDY, ORANGE COUNTY. VOLUME 1: EXECUTIVE SUMMARY AND PLANNING ANALYSIS</title>
      <link>https://trid.trb.org/View/150820</link>
      <description><![CDATA[The volume is one of five which document two separate planning case studies examining the feasibility of dual mode transit systems in (1) Orange County, California, and (2) Milwaukee, Wisconsin. The main objective of this case study was to provide feedback to dual mode system design efforts. Before the dual mode system development proceeded to large-scale demonstration and testing, cost, performance, and demand relationships needed to be investigated analytically so that efficient design characteristics and operating regimes could be prescribed. The study incorporated a full-fledged technical planning analysis in a real urban area assuming that the required dual mode vehicles and control systems were available. Supply and demand relationships were parameterized so that the impacts of variations in factors such as access/egress time, guideway speed, headways, fare level, vehicle size, etc., can be determined.]]></description>

      <title>COMMUNITY TRANSIT COMES TO KODIAK</title>
      <link>https://trid.trb.org/View/539684</link>
      <description><![CDATA[Four years after the initial decision, rural transportation has come to Kodiak, Alaska, and the initial results are optimistic. Kodiak is no ordinary rural community.  Its vast expanse of untamed wilderness, home to countless Kodiak brown bear, bald eagles and more, makes this island truly unique.  But like any other rural area across the U.S., it needs community transportation to help people get to work, to human services. Serving senior citizens, commuters, students, Kodiak Area Transit System (KATS) has filled that mobility void.]]></description>

      <title>UPTOWN TO DOWNTOWN IN 1980</title>
      <link>https://trid.trb.org/View/130415</link>
      <description><![CDATA[A TRANSPORTATION NEEDS STUDY OF A TOTAL URBAN ENVIRONMENT WAS CONDUCTED. A MOVING BELT SYSTEM WAS RECOMMENDED FOR MAJOR ACTIVITY CENTERS, SUCH AS CENTRAL BUSINESS DISTRICTS, AIR TERMINALS, UNIVERSITIES, AND SHOPPING CENTERS. SMALL AUTOMATED CARS WERE RECOMMENDED ALSO AS A POSSIBILITY TO CARRY PEDESTRIANS AT FIVE TIMES WALKING SPEEDS. FOR LOCAL NEIGHBORHOOD TRANSPORTATION TWO BASIC SYSTEMS WERE CONSIDERED TO PROVIDE GOOD SERVICE. THE PUBLIC AUTOMOBILE SERVICE WOULD SERVE ACCREDITED DRIVERS AND A RADIO- DISPATCHED MINI-BUS (THE DIAL-A-BUS) WOULD SERVE NON- DRIVERS. THE PUBLIC AUTOMOBILE SERVICE VEHICLES WILL BE RENTED BY THE TRIP AND CHARGES WILL REFLECT BOTH THE DISTANCE TRAVELED AND TIME IN USE. FOR EXTENDED AREA SERVICE TRANSPORTATION, AN AREA-WIDE NETWORK OF SPECIAL GUIDEWAYS FOR AUTOMATED VEHICLES WAS RECOMMENDED. THE GUIDEWAYS WOULD BE LAID ON A GRID-LIKE PATTERN WITH LINES SPACED 1/2 TO 3 MILES APART DEPENDING ON THE VOLUMES OF TRAFFIC. VEHICLES WOULD RIDE ON RUBBER-TIRED WHEELS AND BE DRIVEN BY ELECTRIC MOTORS. THE ROUTING AND DISPATCHING OF VEHICLES WOULD BE MANAGED BY A CENTRAL COMPUTER THAT FURNISHES INITIAL ROUTING INFORMATION TO EACH VEHICLE AT THE ORIGINATING STATION AND CONTINUALLY UPDATES THE ROUTES AS THE VEHICLE TRAVELS THROUGH THE NETWORK. SOME CONSIDERATION WAS GIVEN TO RAPID TRANSIT SYSTEMS: FAST TRANSIT LINK SERVICE OR FTL. TWO EXAMPLES OF FTL SYSTEMS WERE EXAMINED. BOTH WOULD USE AIR CUSHIONS FOR SUSPENSION AND BE PROPELLED BY LINEAR ELECTRIC MOTORS. TOTAL RESEARCH, DEVELOPMENT, AND DEMONSTRATION COSTS FOR ALL SYSTEMS WERE ESTIMATED TO BE MORE THAN TWO THIRDS OF A BILLION DOLLARS OVER A PERIOD OF 13 YEARS.]]></description>

      <title>A CONSIDERATION OF UNDERGROUND URBAN TRANSPORT SYSTEMS' METROPOLITAN RAILWAY UNDERGROUND TRAMWAY OR MOTORBUS TUNNELS</title>
      <link>https://trid.trb.org/View/131637</link>
      <description><![CDATA[IN MEDIUM AND LARGE-SIZED CITIES AT PRESENT SERVED BY TRAMWAYS AND MOTORBUSES, CONSIDERATION MUST BE GIVEN TO THE OPERATION OF TRAMWAYS IN TUNNELS IN HIGH-DENSITY TRAFFIC AREAS, I.E. IN THE CENTER OF THE CITY. WHEREVER POSSIBLE, THE TRACKS REMAINING ON THE SURFACE IN THE SUBURBAN AREAS SHOULD BE PLACED ON A SEPARATE RIGHT-OF-WAY. AT THE SAME TIME TRAMWAYS SHOULD BE AFFORDED EVERY FACILITY AND IF POSSIBLE BE GIVEN PRIORITY AT CROSSINGS WHERE THEY HAVE TO CUT ACROSS THE GENERAL FLOW OF TRAFFIC. IN CITIES WITH MORE THAN 500,000 INHABITANTS THE UNDERGROUND TRAMWAY MUST BE CONSIDERED AS AN INTERMEDIATE STAGE PRIOR TO METROPOLITAN RAILWAY OPERATION WITH LARGE VEHICLES. TAKING INTO ACCOUNT THIS RESTRICTION, ALTHOUGH THE UNDERGROUND TRAMWAY SYSTEM IS A TRANSITIONAL ONE, IT IS VERY EFFECTIVE. IT CAN BE IMPLEMENTED RAPIDLY, CUTS INVESTMENTS WHILE MAKING PROVISION FOR THE FUTURE. IN PLACES WHERE TRAMWAYS ARE IN PROCESS OF DISAPPEARING, PLANS MUST BE DRAWN UP IMMEDIATELY FOR THE CONSTRUCTION OF TUNNELS FOR MOTORBUSES IN CONGESTED AREAS, QUITE APART FROM RESERVING SPECIAL TRAFFIC LANES FOR THEM. THE ASSISTANCE SHOULD BE DIRECTED BOTH TO WORKS TO SEGREGATE PUBLIC SERVICE VEHICLES FROM THE GENERAL TRAFFIC AND TO THE PROVISION OF FACILITIES AND RIGHT-OF-WAY OVER OTHER TRAFFIC RUNNING ON THE ROAD SURFACE. /AUTHOR/]]></description>

      <title>FREE TRANSIT: PRACTICAL GOAL OR IMPOSSIBLE DREAM?</title>
      <link>https://trid.trb.org/View/130644</link>
      <description><![CDATA[AN EXAMPLE OF WHERE FREE TRANSIT CAN AND DOES WORK IS COMMERCE, CALIFORNIA, WHICH FOUR YEARS AGO LAUNCHED A FREE- RIDE POLICY ON ITS BUSES. RATHER THAN LET AN AILING BUS OPERATION JUST DISAPPEAR, THE CITY DETERMINED THAT TRANSIT MUST CONTINUE TO RUN. IN 1965, THE LINE CARRIED ALMOST 500,000 RIDERS, AND THE OPERATION COST ABOUT $80,000 FOR PERSONNEL, FUEL AND MAINTENANCE. COST WERE PAID OUT OF TAX DOLLARS, ON THE GROUND THAT TRANSIT IS AN ESSENTIAL MUNICIPAL SERVICE. /AUTHOR/]]></description>

      <description><![CDATA[THE QUESTION OF HAVING REGULAR PUBLIC TRANSPORTATION SERVICE IS OF INCREASING IMPORTANCE. MORE ATTENTION MUST BE PAID TO THE PROBLEM SINCE THE TRAFFIC CONGESTION IN TOWNS IS SUCH THAT MAINTAINING SCHEDULES BECOMES MORE DIFFICULT. IN THIS ARTICLE THE AUTHOR DISCUSSES THE RECENT PROGRESS MADE IN AUTOMATIC TRAFFIC CONTROL AND ITS CONTRIBUTION TO REGULAR MASS TRANSPORTATION SERVICES. /AUTHOR/]]></description>

      <description><![CDATA[THE METHOD, RATIONALE, AND SIGNIFICANCE IS EXPLAINED OF SYSTEMS ENGINEERING APPLIED TO METROPOLITAN DEVELOPMENT. IT IS INTENDED TO AID IN THE CREATION OF AN URBAN SYSTEMS ENGINEERING GRANTS PROGRAM WHICH WILL COMPLEMENT EXISTING 701 AND 702 PROGRAMS. THE DISCUSSION DEALS WITH THE CONTEXT AND NATURE OF SYSTEMS ENGINEERING AS AN ELEMENT OF COMPREHENSIVE PLANNING AND AS APPLIED TO PROBLEMS OF METROPOLITAN PUBLIC SERVICE. PROBLEMS ARE DEFINED WHICH GENERATE PUBLIC SERVICE NEEDS. THE MACHINERY FOR THE SATISFACTION OF THESE NEEDS IS A NETWORK OF INTERACTING SYSTEMS WHICH MUST PROPERLY BE TREATED AS SUCH RATHER THAN AS A SERIES OF INDIVIDUAL PROJECTS. SYSTEMS ENGINEERING IS VIEWED AS A METHODOLOGY FOR RATIONALLY SOLVING SPECIFIC METROPOLITAN PROBLEMS RELATED TO WATER SUPPLY, WASTE DISPOSAL, PUBLIC HEALTH AND TRANSPORTATION. OTHER POTENTIALLY BENEFICIAL APPLICATIONS ARE BRIEFLY OUTLINED. A SET OF WORKING PAPERS CONTRIBUTED BY MEMBERS OF THE COMMITTEE ACCOMPANIES THIS REPORT. /AUTHOR/]]></description>

      <title>COORDINATION OF RURAL PUBLIC TRANSPORTATION SERVICES IN THREE SOUTHEASTERN STATES</title>
      <link>https://trid.trb.org/View/356123</link>
      <description><![CDATA[The study examines eight coordinated systems in the states of Alabama, Georgia, and North Carolina.  Coordination was broken into three types:  institutional ridesharing, purchase of service contracts, and consolidation of services under one provider.  In-depth case studies examine the processes which developed the coordinated systems, and the operational and financial aspects of these systems. Coordination efforts at the state level are also examined in all three states.  The report should be especially useful to small transit operators and social service providers with needs for transportation.]]></description>
