Throughput Capacity Estimation for Convoy Movement in Linked Roads

Sarker, Bhaba R. / Baylot, E. Alex

This research is aimed at finding the throughput rate of convoy movement in a transportation network. The primary goal of the study is first to find the throughput rate that will facilitate an estimate of the time to logistically deploy one unit, omnidirectionally (radially), to different localities during different elapsed times. The concept of average speed on a linked road is used to estimate the throughput rate of the vehicles. Several models for physical boundary conditions have been established to estimate the turning delay time in a convoy movement through streets in an urban environment under different conditions of road geometry. Special cases are also evaluated to study the capability of the general models. As a primary emphasis of the study, delay time at a turning is modeled to estimate the individual arc capacity and linked-arcs capacity. A model to estimate the average velocity in a linked road is developed to determine the average throughput rate of a route for a convoy movement. In all modeling approaches, detailed descriptions of the derivations are illustrated with numerical examples and figures.
