ANALYSIS OF OPTIMIZE TRAFFIC IN ALSAHARA UNSIGNALIZED INTERSECTION LIBYA

Abstract

The background and objective study is Introduction of this study Contains the background of the research topic ,the location intersection in this study are located in SABHA city Libya considering ALSAHARA intersection is one of the important intersections in SABHA city having crowded traffic especially in peak hours.The city is also the biggest city in Libya had a population 230.000 people to be crowded and has big traffic. where studies the unsignalized intersection ALSAHARA of case of traffic congestion and also accident as it is shown in problem statement , also the objectives of this study which contain the solution for this problem, which aims to solve the multi scope of the study. Research methods and includes all the details of the data and methods of data collection and data collection times at the intersection of ALSAHARA. The result of study must be includes analysis of the data and the results of data analysis, where we found that really rush hour this intersection the morning .And also the degree of saturation for this time ,must make signalized intersection, the result and value show suitable saturation level on unsignalised intersection and the value is consistent with the standard used but the safety on traffic is still low. The saturation level needs to be tested after five years to see if the standard is still suitable or not.By the result of analysis it is obviously seen that the saturation level value is high and more than Highway Capacity Manual (IHCM1997). Conclusions and recommendations where we can deduce that at the intersection .That is why it is necessary to analysis intersection with signalized and by considering the value of degree saturation is consistent and suitable with the standard used as the conclusion it is suggested to perform ALSAHARA intersection with signalized .Unsignalised intersection Highway Capacity Manual (IHCM 1997). Key word:Sabha City, Al Sahara Intersection, Traffic congestion.
