Abstract

This research was aimed at finding the throughput rate of convoy movement in a transportation network. The primary goal of the study was first to find the throughput rate that will facilitate to estimate the time of deployment of logistics unit omni-directionally (radially) to different localities at different elapsed times. Several models for physical boundary conditions have been established to estimate the turning delay time in the 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 for average velocity in a linked-road is developed to estimate the average throughput rate of a route for convoy movement. In all modeling approaches, detailed descriptions of the derivations are illustrated with numerical examples and figures. The concept of average speed on a linked-road is used to estimate the throughput rate of the vehicles.
