Improving public transit access to in-city villages

Rapid urbanisation results in the emergence of in-city villages in many developing countries. The lack of public transit access has been a long-standing problem for the residents in such villages. Here we develop a new mathematical model for adding stops onto the existing transit routes passing by the in-city villages, where the stops are decided by the optimisation of an objective function, which consists of the total supplier and user costs. Numerical examples are given to demonstrate the usefulness and efficiency of the proposed model for improving the transit access to the in-city villages.
