Abstract
Automatic control systems permeate life in all advanced societies today. Such
systems act as catalysts in promoting progress and development. They are
integral components of any industrial society and are necessary for the
production of standardized and quality goods. Suitable signal plans at each road
intersections can be used to solve the problem of traffic flow. These plans could
be fixed-time, time varying, or traffic actuated. Traffic control systems have
evolved during the 20th century in response to the growth in automobile density.
Hence, traffic systems must be organized and controlled carefully in order to
operate efficiently and smoothly and meet the planned traffic control
requirements. The advent of computers as control elements has advanced the
technology in the automation of vehicle actuated traffic control.
In this research project we focused and designed an automatic vehicle actuated
traffic control system for use at intersections on the road network.Astudy of the
road network in Nairobi was done and the nature of traffic density. A sensor was
then developed to detect the presence of vehicles and determine the length of the
vehicle queues. A computer was used to a study of the road network in Nairobi
was done and the nature of traffic density. A computer was used to process the
signals from the sensors and allocate more time for traffic to flow on the street
with longer queue.
A program was developed so that the computer allocated the timing sequence
depending on the sensor status. The system can therefore be used to optimize
traffic flow by ensuring that longer queues have more time for traffic to flow
