Simulating public transport priority measures using AIMSUN

The public transport capabilities of AIMSUN are investigated through the implementation of a case study. It is noted that public transport facilities are simulated through the implementation of bus stops and creation of public lines. Physical measures such as bus lanes are implemented with the use of reserved lanes in the required sections in the network. Transit signal priority (TSP) measures are implemented in AIMSUN with the use of GETRAM extensions to interact with existing network equipment such as detectors and external controllers. Through simulation, public transport priority measures are found to be effective in reducing the overall delay time for the public transport vehicle. Strategies such as signal coordination, implementation of bus lanes and TSP involving green extensions and early green measures are implemented. Although increases in delay times for the general traffic is often cited as a disadvantage for TSP measures, preliminary investigation suggests that the reductions in delay times by the public transport users far outweigh the increases in delay time for the general traffic on a per user basis.
