Route Planning Made Easy - An Automated System for Sri Lanka
  Commercial cities like Colombo constantly face to problem of traffic congestion due to the large number of people visiting the city for various reasons. Also these cities have a large number of roads with many roads connecting any two selected locations. Finding the best path between two locations in Colombo city is not a trivial task, due to the complexity of the road network and other reasons such as heavy traffic, changes to the road networks such as road closures and one-ways. This paper presents the results of a study carried out to understand this problem and development of a system to plan the travel way ahead of the planned day or time of the journey. This system can compute the best route from between two locations taking multiple factors such as traffic conditions, road closures or one-way declarations etc., into account. This system also has the capability to compute the best route between any two locations on a future date based on the road conditions on that date. The system comprises three main modules and two user interfaces one for normal users and the other for administrators. The Administrative interface can only be accessed via web browser running on a computer, while the other interface can be accessed either via a web browser or a GPRS enabled mobile phone. The system is powered mainly by the Geographic Information System (GIS) technology and the other supporting technologies used are database management system, ASP.Net technology and the GPRS technology. Finally the developed system was evaluated for its functionality and user friendliness using a user survey. The results of the survey are also presented in this paper.
