ANALYSIS OF INTERSECTION IN DERNA CITY (CASE STUDY: INTERSECTION OF REPULIC STREET AND REAL ESTATE STREET)

Abstract

ABSTRACT Rapid growth and development of Derna City in terms of population and the number of comers drive the pressure on transportation system. The appearing problem of traffic is traffic density and long lasting jam. Traffic jam is one of important things needed to solve especially on unsignalised intersection in a busy city like Derna City at peak hour and it is needed to observe if the systems have been suitable with the standard or not. This study is aimed to reveal the solution in order to minimize traffic density as well as mobility repair by maximizing study of case using method guide from Indonesian Highway Capacity Manual (IHCM, 1997). Location intersection in this study are located in Derna City, Libya considering Republic Street is one of pivotal cities in the city having crowded traffic especially at peak hour. The city is also one of areas with the most rapid population growth in Libya. In this case, intersection on Republic Street and Real Estate street are chosen to be the objects of study because of their traffic density. 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. Thus, the saturation level needs to be tested after five years to see if the standard is still suitable or not. From the result of analysis, it is obviously seen that the saturation level value is high. That is why it is necessary to plan intersection with signalised intersection and by considering the value of saturation degree is consistent and suitable with the standard used. As the conclusion, it is suggested to perform intersection with signalised intersection in the next.
