ABSTRACT
Transportation system of a city affects all aspects of its citizen’s economic and personal activities. At a general level, the traffic problem considered as a situation of mismatch between supply (i.e., roads and their capacity) and demands (i.e., travel needs). The city administrators have tried to balance it by creating infrastructures (e.g., new roads, expanding capacity, under pass) or policy changes (e.g., banning heavy traffic movement during peak or day hours). Major problems that motorists are facing on highways intersection are congestion, accidents, and costs. Too many automobiles, trucks, buses, bicycles, and pedestrians are attempting to use the same space to reach their destiny . Transportation problems are evident at some locations with complex roadway geometrics. So a traffic study is to be conducted to quantify the extent of transportation problems. This study aims to gain information and understanding about traffic system through the derivation of traffic information from traffic data, and then to apply this information in the assessment of the performance of traffic systems and their interaction with land use activities. This research is an effort to provide suggestion and recommendations to enforce an efficient traffic flow system. The coefficient of correlation (R) proved to have the best fit with higher confidence and les variation for a two- lane highway tan one lane highway. The space mean speed (u) and density (k) relationship for the one-lane highway are, u=39.57-0.0025k,u=58.67-0.01kand u=33.15-0.002k, where as the space mean speed (u) and density relationship for the one- lane highways are u= 53.84-0.0016k, u=29.76-0.003k respectively. This research provides practical applications for speed estimation , construction ,maintenance and optimization of the highways using the speed-density models which will eliminate traffic monitoring, traffic control management , traffic forecasting and model calibration.
