Control of Congestion at Highly Saturated Signalised Intersections: Experiments on Rama 4 Road, Bangkok

INTRODUCTION

This working paper is the third in a series of three on the control of congestion at highly saturated signalised intersections. The other papers in the series are:

WP 220 Control of Congestion at Highly Saturated Signalised Intersections: 1 - Survey Methods

WP 221 Control of Congestion at Highly Saturated Signalised Intersections: 2 - Experiments at an Isolated Junction.

After a brief explanation of the purpose of the study, and the part played by the Rama 4 experiments, this paper describes how the input data for the experiments was collected, updated and prepared for use in standard signal setting programs. The conduct of the actual experiment is then described followed by results and conclusions thereof.
