In this paper, a person-delay-based optimization method is proposed for an intelligent TSP logic that enables bus/signal cooperation and coordination among consecutive signals under the Connected Vehicle environment. This TSP logic, called TSPCV-C, provides a method to secure the mobility benefit generated by the intelligent TSP logic along a corridor so that the bus delay saved at an upstream intersection is not wasted at downstream intersections. The problem is formulated as a Binary Mixed Integer Linear Program (BMILP) which is solved by standard branch-and-bound method. Minimizing per person delay has been adopted as the criterion for the model. The TSPCV-C is also designed to be conditional. That is, TSP is granted only when the bus is behind schedule and the grant of TSP causes no extra total person delay.
Introducing public bus transit system in Indian cities raises many challenging issues of different nature ranging from technical to operational. The present study examines the impact of a new public bus transit system by applying a binary logit analysis for assessing the possible variation in modal shift behavior. The case study of mode-choice was developed, calibrated, and validated using socio-economic data collected on six proposed corridors in the city of Bardoli, Gujarat, India. Traffic quality parameters, such as average speed, delay, congestion, travel time, and travel cost were modeled to investigate the impact of the new bus transit system in VISSIM environment. The probability of an overall modal shift to proposed bus transit system corridors ranges from 45% to 51%. The maximum modal shift ranges from 80.58% to 87.40% for three-wheelers (para-transit) followed by bicycle and walking mode. However, cars have the least modal shift ranging from 6.78% to 11.49% and 37.38% to 45.46% for two-wheelers. The average speed of the bus transit system in both directions could reach 47.75–49.59 kmph with 15 min frequency. Likewise, mean travel time was estimated from 1.3 to 1.6 min per km and average commuter cost of less than Rs. 1.0 per km for bus transit with insignificant delay and congestion. Introduction of the new public bus system shows promising results and has to play a significant role in developing a sustainable urban public transportation system. These findings can be used to form the basis for the implementation of the new public bus transit in peer cities with relatively similar sizes, which may impact an inhabitant sustainable choice on ridership in due course.
