Benefit

In the central area of Chicago, a 2004 feasibility study indicated that collision warning systems on buses would not be cost-effective in the near term.

Summary Information

This study investigated the feasibility of implementing a Cooperative Vehicle-Highway Automation System (CVHAS) to improve the performance of bus rapid transit (BRT) operations and freight movement in Chicago, Illinois. The sites chosen for the case study included a metropolitan bus rapid transit circulator system and an intermodal freight interchange system at the port of Chicago.

ANALYSIS OF CVHAS APPLICATIONS FOR BUSES

This case study investigated the feasibility of implementing CVHAS technologies to improve the performance of bus transit in the central area of Chicago. The potential impacts of transit signal priority, collision warning, precision docking, and automatic steering control were analyzed. The analysis included three case studies.
  • East-West Loop arterial
  • Underground Monroe busway
  • Clinton-Carroll Avenue busway
An incremental benefit-cost analysis was conducted to evaluate the potential impacts of CVHAS technologies on each transit corridor. Initially, the physical and transit operational characteristics of each corridor were studied to identify performance measures that could be used to measure the effects of CVHAS technologies and estimate potential cost effectiveness of implementing each technology.

FINDINGS (Subject to the data limitations discussed in the report)

Considering the infrequency and uncertainties associated with bus crashes, the deployment of collision warning systems in the near-term appeared not to be worth the investment. In the long term, however, return on investment for collision warning systems has more potential.
