Abstract
The traffic control system of the Tokyo Metropolitan Expressway is considering an implementation of the online short-term prediction by the real-time simulation. Some modules for making exact traffic conditions prediction at the incident congestion -“Emergent Bottleneck Detection", “Lane Blockade Time", “Road Capacity", “On-Ramp Traffic Volume Change", and “Off-Ramp Conversion"-were developed. This research reports the result of having analyzed the influence which those modules have on the predictive simulation.
