Abstract

One of the big problems facing city municipalities is the traffic congestion. It makes life in cities uncomfortable for people. Every year governments spend huge budgets to solve this problem. Koya is suffering from this problem especially at rush traffic hours. In this paper, the traffic congestion problem is studied for the road connecting Sawz Square and Shahidan Square in Koya city. The congestion is measured by determining the level of service of the street (LOS) through calculating the traffic flow rate of the street and free flow rate; the LOS level was D. For determining peak hour traffic volume the calculation is made through the manual counting of vehicles and multiplying by passenger car equivalent (PCE) where the speed is reduced to (10 km/hr). In addition, the topography, elevations and alignments of the road are studied. This paper determined the real causes of the traffic congestion in this specific street in Koya city and proposed solutions for solving the problem.
