Abstract


Intersections have been identified as the most complex location in a traffic system. This is due to the number of movements that occur within an intersection. Delays have a negative impact on motorists as well as in the economy. Traffic signals are implemented to reduce this burden, but this is determined by the signal timing. The pre-timed traffic signal control assigns the right of way at an intersection according to predetermined schedule; and does not accommodate short-term fluctuations. The purpose of this study was to estimate the delay at an intersection using queuing models. The study uses field data collection.
