Abstract:A new TSP logic was proposed, taking advantage of the resources provided by Connected Vehicle (CV)
technology, including two-way communication between the bus and the traffic signal controller, accurate bus
location detection and prediction, and the number of passengers. The TSP logic used was green time reallocation,
which only moves green time instead of adding extra green time. The TSP was also designed to
be conditional. That is, delay per person was used as one of the most important criteria to decide whether
TSP is to be granted. The logic developed in this research project was evaluated in two ways with analytical
and microscopic simulation approaches. In each evaluation, the proposed TSP was compared against two
scenarios: no TSP and conventional TSP. The measures of effectiveness used were bus delay and per
person delay of all traffic users. Evaluation results show that the proposed TSP logic reduces bus delay from
84% to 9% compared to conventional TSP and from 88% to 36% compared to the no-TSP condition. The
range of improvement corresponds to the four different v/c ratios tested, which are 0.5, 0.7, 0.9, and 1.0. No
negative effects were caused by the proposed TSP logic.
