Sri Lankan road transport planners develop low cost traffic forecast

ECONOMYNEXT – Sri Lankan road transport planners have developed a new method to forecast future demand for road use drastically reducing the cost of surveys as part of measures to improve traffic flows and cope with worsening congestion, an official said. 

There was growing interest in research among staff of the Road Development Authority (RDA), said Namalie Siyambalapitiya, director of planning at the RDA.

“I’ve been working for 30 years in road and transport matters and have found it very difficult to encourage our staff to do research,” she told a news conference.

But interest grew after a conference last year by the Sri Lanka Society for Transport and Logistics (SLSTL) to promote research and development in the transport and logistics sector in Sri Lanka called ‘R4TLI-2017’ or Research for Transport & Logistics Industry.

“Now our staff realise the need for research and see good results of being involved in research,” Siyambalapitiya said.

The new traffic forecast method developed by young staff members of the RDA planning division enable survey to be done in a shorter period, she said.

“We conduct surveys to forecast future traffic demand and do modelling but sometimes we can’t do surveys on each location all the time. Two of our staff members developed a method to do a survey for limited period and enhance it for 24 hours,”  Siyambalapitiya said.

“This can be used to calculate future demand for road use and has drastically reduced cost of conducting surveys.”

The work will be presented at  the second Research for Transport & Logistics Industry conference, to be held this Saturday, by SLSTL which aims to build a platform where the needs of the industry can be discussed and scientific processes showcased through research presentations.
