Bus Network Design Procedure Using Mathematical Programming Model for Terminal Location Finding

1. Virtual transit network with the highest access for users

2. Travel and transit demand forecasting and assignment

3. Calculating the potential of nodes as terminal with the model using the outputs of

EMME/2

4. Defining the number and location of terminals (output of Mathematical

Programming Model)

5. Designing the transit routes by connection between terminals

6. Determine the bus stops location

7. Travel and transit forecasting and assignment for new transit system

8. Fleet allocation
