Multimodal Assignment Procedure Auto assignment • N: The Number of Active Buses • voleqtr: The Bus Equivalent Passenger Car • vauteq: The Bus Equivalent Passenger Car Factor • hdwy: Headway of Bus Rout • lay1 and lay2: The stop over in the Beginning End of Rout • timtr: Transit Travel Time for the Rout (A function of Auto Travel Time) • speed: Initial Speed for the bus Rout • len: The Length of Route Transit Assignment Auto assignment Transit Assignment
Complementary Models • Car Ownership Model Function of Income and Macro Policies • Auto Travel Time Functions Function of Total Volume (Total Equivalent Passenger Car, Auto and Transit)) • Intersection Delay Time Functions Function of Total Volume (Total Equivalent Passenger Car, Auto and Transit)) • Transit Time Function Function of Auto Travel Time • Dwell Time Models Dependent to Boarding Numbers, Bus Type, The Number of Bus Doors, Validated by a Survey Results • Terminal Location Finding Models Based on Mathematical Programming Model and a Function of Potential of Boarding and Alighting at Nodes • Air Pollutions and fuel models
Using the Transportation Model of Cities provided by EMME Transportation Studies and Projects Tehran Bus Network re-design in order to adjust with Metro Lines Updating the Transportation System Data Tehran Transportation System Data in 2003
Optimization the Efficiency of Tehran Transit System including Bus and Metro (Through Bus Network design in order to adjust with Metro Lines)
Bus Network Design Procedure Using Mathematical Programming Model for Terminal Location Finding Virtual transit network with the highest access for users Travel and transit demand forecasting and assignment Calculating the potential of nodes as terminal with the model using the outputs of EMME/2 Defining the number and location of terminals (output of Mathematical Programming Model) Designing the transit routes by connection between terminals Determine the bus stops location Travel and transit forecasting and assignment for new transit system Fleet allocation
