Abstract:
This research study deals with the analysis and evaluation of road traffic accident counter measures in Greater Bangkok Metropolitan Area. The purpose of the study is to evaluate some counter measures to reduce road traffic accident. The study concentrated on 7 projects which were implemented by BMA (Bangkok Municipal Administration) during 1977 to 1979. They are as followed - New Petchaburee Road - The construction of a new pedestrian foot-bridge in front of Wat Dishongsaram. - Lan-Luang Road - The improvement of roadway by overlay using hot-mix asphalt concrete. - Din-Deang Road - The improvement of traffic signal, signal holder, post etc. at Din Deang - Rajaparop intersection. - New Petchaburee Road - The improvement of signalize intersection by using lane marking, crossing lane and curb marking at Petchaburee-Asoke intersection. - Rama I Road -The construction of a new pedestrian foot-bridge near Kasatsuk Bridge. - Pitsanulok Road - The improvement of signalize intersection by using lane marking, crossing lane and curb marking at Pitsanulok- Rajasema intersection. - And Prasumenru Road - The improvement of zebra crossing and lane marking along the section . The results of the study reveal the following. - For statistical analysis - The results of the significant test by using poisson and binomial curve shows that most counter measures has little effect on road traffic accident reduction, and accident is not significantly reduce. - For economic analysis - The results of the benefit cost ratio and net annual benefit of each implemented projects shows that each counter measures implemented yield economic benefit ranking from top to the lowest as follows. - The improvement of zebra crossing and lane marking by using color paint. - The improvement of signalize intersection by using lane marking, crossing lane and curb marking. - The improvement of roadway by overlay using hot-mix asphalt concrete. - The improvement of street crossing by construction a new pedestrian foot-bridge. These counter measures can be improved by using more consideration in order to help reduce more accident and will significantly reduce the total no. of accident.
