2012 Transportation Development Plan for Colombo City
Development of ways to reduce traffic congestion in Colombo City and focusing at smooth traffic circulation within the city, especially during 2013 Common Wealth Meetings to be held in Colombo. Client: Ministry of Transport
2011/ Traffic Impact Assessment (TIA):
2012 Traffic impact assessments were done for many proposed developments including multi storied housing developments, fuel stations, office complexes, and shopping complexes, etc. within the Colombo city as well as in other areas of the country.
2011 Railway Line Electrification Pilot Project :
Economic Feasibility Study for railway line electrification pilot project. Client: Sri Lanka Railways.
Economic analysis was carried out considering costs and benefits of the proposed pilot railway electrification from “Veyangoda” to “Kaluthara”, an 80km section.
2011 Formulation of Criteria for Placement of CEYPETCO New Filling Stations:
Development of a methodology to identify geographical locations to establish new fuel stations Island wide. Client: Ceylon Petroleum Corporation.
Criteria were developed using population data, distance from existing fuel station, traffic volume, etc.
2011 Railway Line Extension Project :
Economic Feasibility Study for “Kelani Valley” railway line extension. Client: Sri Lanka Railways.
Economic analysis was carried out considering costs and benefits of the proposed development.
2011 Decade of Action for Road Safety 2011-2020:
Preparation of a National Action Plan in accordance with the Global Plan Developed by UN & WHO, in order to improve the road safety in Sri Lanka during next decade.
Various tasks outlined in global plan was identified and customized to suit Sri Lankan conditions. Under different phases, actions were clearly identified and lead agency was assigned. Key performance indicators were also set to monitor the program effectively.
2011 Seat Belt and Helmet Usage in Sri Lanka:
To see the seat belt and helmet usage in Sri Lanka before and after implementation of seat belt law.
Seat belt and helmet usage data were collected from all provinces in the country as per the requirement of National Safety Council. Further, analysis was done and conclusions were made. This project was funded by WHO.
2011 Commuter Traffic in Colombo City:
To study the commuter traffic movement in Colombo city.
Traffic counts (MCC) were done at major roads entering and leaving Colombo city and analysis was done based on such data.
Developing Driving Cycles for Sri Lankan Conditions and Setting up Appropriate Emission Standards:
Emission standards are need to be fixed based on Sri Lankan road and traffic conditions, but no study has been done to determine such cutoff levels and industry is lacking in that aspect. The objective of this study is to set up such standards for emissions using driving cycles (well practiced method in other countries).
Development of Improved Guideline for Traffic Signal Design:
Objective of this research is to develop a guideline for traffic signal design that can accommodate individual travel time saving, environmental pollution and synchronization of closely spaced signalized intersections.
