Traffic job has aggravated by the attending of all signifiers economic, commercial and administrative maps in the metropolis.The metropolis of Colombo attracts about 1.5 Million drifting population on a on the job twenty-four hours and with the add-on of the resident population in the metropolis. The entire population in the metropolis increases to more than 2 Million during the daylight. It is estimated that approximately 50 % of the transposing population arrives in the metropolis for employment or to link in commercial activities and or to go to educational establishments.

The remainder comes to the metropolis for assorted other intents.Commuting population are used assorted signifiers of transit to come in the metropolis. Both the figure of vehicles and the riders come ining the City are increasing twelvemonth by twelvemonth.

The combination of these facets outcome is a greater attractive force of the metropolis for people from the remainder of the state therefore worsening the conveyance job in the metropolis of Colombo.

There are illegal buildings and street sellers are making their concerns in waysides. In most roads passage through waysides is obstructed by these street sellers.

Uncontrolled wayside development and concerns has reduced the capacity of the route web.
