Call for Entries: recruiting new members to two new EASTS-IRG proposals

Dear Regular Members of EASTS,

Our colleague, Mr. Granie R. Jayalath (Sri Lanka), would like to propose two new EASTS-IRGs, and we are helping him to recruit new IRG members. (for detail about IRG, see

Theme-1: Rural mobility with particular reference to developing countries.
Theme-2: Characterization of toll road user preferences with particular reference.
(for more detail about researches, see the bottom of this message.)

If you are interested in joining one of two new EASTS-IRGs, please send your information(*) to “E-mail:“.

Theme-1: Rural mobility with particular reference to developing countries.

The efforts of governments of many developing countries and donor agencies to improve rural mobility have so far focused on improving and expanding road infrastructure networks. Over the many years there has been massive spending on rural road provision, yet the interventions have not effectively resolved the rural mobility burden, particularly in developing countries. Beside above facts, the rural population been quite large, generally exceeding 70% of total populations in developing countries and characterized with low motorized vehicle ownerships, the planning philosophy followed by local executing authorities remains automobile dependent. As such, current mobility provisions are not optimized hence does not commensurate with the exact characteristics of demands for rural mobility.
Current approaches are unable to assess and characterize the nature of demand for mobility of rural village commuters. The objective of the research is to develop an approach for estimating demand for rural mobility using “Mobility Biographies”.

Theme-2: Characterization of toll road user preferences with particular reference.

During the planning stage of Colombo-Katunayaka Expressway (EO3), of Sri Lanka, the expressway that links the International Airport to the capital city of the country, it was presumed that gradual replacement of Manual Toll Collection (MTC) gates by Electronic Toll Collection (ETC) gates will certainly be an effective strategy to maintain the design throughputs via all tollbooths, during the design life. To start with, when one MTC gate per plaza was converted to an ETC gate, an unexpected phenomenon occurred, i.e. the ETC user registrants after reaching an average of 450 user/month came to a standstill thus resulting an average throughput of 60-80 veh/hour during peak hours, instead of its capacity of 1200veh/hr. This situation has brought unexpected congestion at MTC tollbooths and financial losses, thus affecting the projected benefits of the investment. This situation warranted the need to have an approach to characterize the growth phenomenon of potential ETC users, mak!
ing particular reference to the socio-economic circumstances of users.
Current approaches used for the prediction of demand for ETC tag Usage of toll roads have not been successful, particularly in the context of developing countries. A new approach based on socioeconomic attributes for modelling the growth trends of ETC users is needed.
