Along Colombo - Galle road (A02) in Sri Lanka (one of the main radial arterial roads connecting southern Sri Lanka with the Colombo capital) few years back due to heavy in flow of morning traffic towards Colombo, a transit lane for public and private buses was introduced (kerb side lane was totally dedicated to buses only, as a solution to address this heavy inflow of traffic to Colombo). This kerb side transit lane was introduced between Dehiwala and Bambalapitiya on trial basis with the assistance of the Colombo city traffic police. Although the new introduction seem to be successful initially, but with passage of time due to unauthorized vehicles getting to the transit lane for their benefit and also buses not sticking to transit lane, led to a drop of efficiency in the transit lane and finally the trial effort was completely given up.

Through this study it is expected to look at the problem from queuing theory point of view and an attempt is made to find out where the failures took place and expect to bring in positive suggestions and corrective measures.
