Identification And Analysis Of Hazardous Locations And Its Remedial Actions At Major Intersections I N Addis Ababa (A Case Study For Lukuwanda - Megenagna Road

Abstract

Hazardous Road Location is an ever chronic problem in the transportation system soon after the invention and mass production of automobiles. Some of the negative effects of hazardous road are; considerable loss of travel time, higher fuel consumption, more vehicle emission and associated environmental and health impact increased accident risk, stress and frustration on commuters and greater transportation cost. In this MSc thesis the main objective of the study was to identify and analyze the hazardous roads in Addis Ababa along Lukuanda - Megenagna through Piaza road and to indicate its remedial actions.. Because of that there was limited road capacity, on street parking, un-integrated urban planning, and lack of mass transit, accident, poor vehicle condition, very long delay and road side illegal trade throughout the study area. The analysis and identification of HRL consists in the implementation of three types of methods: (i) Based on technical weight of prioritization: Road locations are laid under high, medium and low hazard prone level. (ii) Based on the point density: Which is based on the total number of traffic accident. (iii)Methods based on GIS analysis: The most vulnerable segments have been identified on the basis of the highest number of accidents occurred during the analysis period. The remedial measures indicated in this thesis are related to the type and positioning of the road furniture and these have been grouped into three categories: traffic control devices, road and street design, and traffic calming. Since design details are not presented, the road owner should seek engineering expertise when selecting countermeasures. Several engineering countermeasures like traffic control devices, road and street design and traffic calming on lower-speed roadways have been also identified that can be used to influence to give way for pedestrians, driver speed choice and that address speeding problems.
