Ahmedabad Jnmarg Case Study

Automated Fare collection system

The Ahmedabad Jnmarg was the first system to have an integrated ITS system which integrates AVL and AFC systems. The significant part of this was that it could assigning buses to pre-defined schedules, and in real time. Also an on board driver console lets the driver know by how much he has deviated from the schedule, and so can adjust his speed accordingly. (Vasudevan & Mulukutla, 2015)

ITS data and service optimization

There are systems across the world that analyze such data and optimize the system to best fit the demand while conserving resources. The Tri-met in Portland used it’s ITS system data to evaluate its service operations. It concluded that the scheduling done as per traditional methods incorporated additional layover time to compensate for operator related delays. Such

The system also compared the data from the AVL and Passenger load data to determine if existing frequencies are insufficient or in efficient. The routes with inefficient schedules or erratic passenger load are catered by control actions such as bus holding and bus skipping stops. (Strathman, 2002). Given the case BMTC, there is a need to improve the fleet management and the scheduling. There numerous papers and studies that propose various methods of scheduling, some of which are discussed below.

The first is a hybrid predictive control system that follows a multi objective function. This strategy allows the operator to react dynamically to real time disturbances, and react to them by holding buses at certain stops to maintain the headway between them. The dynamic design of the system requires the demand prediction
