Analytical models of multi-lane traffic flow. Study II. Volume III: Freeway gaps prediction and stability, on-ramp flow estimation, and multi-lane freeway digital simulation.

In the first two reports of this volume statistical methods are applied to obtain gap prediction in the vicinity of an on-ramp, as well as the prediction of on-ramp flow levels. Using aerial experimental data, we showed the feasibility of these prediction strategies. The remaining reports in this volume are concentrated on the digital simulation of freeway traffic. Firstly, an examination of nine freeway simulation models, developed by various research institutes, is carried out. Secondly, a modular simulation model is developed, in several steps, to achieve the ultimate goal of simulating freeways with arbitrary interchange systems and configurations.
