• 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.
