DESIGNING TRANSIT ROUTES AT THE NETWORK LEVEL. IN: CONFERENCE RECORD OF PAPERS PRESENTED AT THE FIRST VEHICLE NAVIGATION AND INFORMATION SYSTEMS CONFERENCE, TORONTO, ONTARIO, CANADA - SEPTEMBER 11-13, 1989

The system described in the study is used to create, analyze and optimize bus route networks. The developed system creates all feasible routes and transferrs that connect every place (node) on the network to all others. Out of this vast pool of routes and transfers, it generates smaller subsets, each maintaining connectivity on the network. For each of the subsets generated, the system fulfils transportation demand by calculating the appropriate frequency for each route. Next, it calculates the optimization parameters for each subset: (a) Passenger Hours (defined as passengers' riding time in a bus on an hourly basis. It measures how much time is spent by passengers on buses); (b) Waiting Time (defined as the amount of time passengers spend waiting at a bus stop); (c) Empty Space - Hours (defined as the unused seats in a bus on an hourly basis. Empty Space _- Hours measures what capacity buses are used); (d) Fleet Size (number of buses needed to provide all trips along the chosen set of routes). At this point, the user is able to choose the most suitable subset, based on the specific optimization parameter he desires. The system has been designed as a tool to plan future transit networks as well as to help maintain existing ones. This flexibility is achieved throughout the system by allowing the user to supply either his own data or to execute it automatically.
