CHAPTER 1: INTRODUCTION

Background of the Study

Traffic-signal control systems coordinate individual traffic signals to achieve network-wide traffic operations objectives. These systems consist of intersection traffic signals, a communications network to tie them together, and a central computer or network of computers to manage the system. Coordination can be implemented through a number of techniques including time-base and hardwired interconnection methods. Coordination of traffic signals across agencies requires the development of data sharing and traffic signal control agreements. Therefore, a critical institutional component of Traffic Signal Control is the establishment of formal or informal arrangements to share traffic control information as well as actual control of traffic signal operation across jurisdictions.

Signal coordination systems are installed to provide access. A traffic-signal system has no other purpose than to deliver favourable signal timings to motorists. The system provides features that improve the traffic engineer's ability to achieve this goal. These are primarily access features. They provide access to the intersection signal controller for maintenance and operations. The more complete and convenient the access, the more efficient the operator will be and the more effective the system.

Significance of the Study

The design, analysis, and evaluation of intelligent transportation systems (ITS) require a good knowledge of traffic flow (pedestrian and vehicular) modeling and control techniques as well as of powerful methodologies from the areas of optimisation, control, networks, and dynamic systems. The objectives of this paper are to analyze the rate at which the vehicular traffic intensity is substituted for increments of pedestrians on footpaths and to evaluate the alternative measures of vehicular traffic intensity.

Aim and Objective of the Study

To analyze the various prospects of the Pre-Timed arterial traffic control system on the roads in the City of Portharcourt, Riverstate, Nigeria. This paper looks into prospects of pre-timed arterial traffic control systems for cities with limited infrastructures. The methodologies for designing a pre-timed arterial traffic controller system were researched. A prototype designed and implemented in field programmable gate arrays (FPGA) is presented. Nigeria Roads have been used to provide data for the design and implementation whereby the neighbouring road intersections within a logically computed radius of less than 250 m qualified for pre-timed arterial traffic controller.
