Vehicular Traffic Flow Theory and Tunnel Traffic Flow Measurements

Vehicular traffic flow has been investigated theoretically and experimentally in order that peak hour collective traffic flow dynamics can be understood and that the peak hour flow through the Callahan Tunnel can be improved by means of traffic flow control and modification. Two theoretical models are suggested, the finite reaction time model and the asymmetrial response model, as predictive of observed traffic density dynamics, wave growth, and asymmetry. Experimentally,a traffic flow profile of capacities, vehicle speeds, and relationships between slowdown wave phenomena and traffic flow, determined. Base on these, it is suggested that traffic flowmay be improved with traffic flow modification procedures.\n
