This study analyzes the traffic characteristics and manage- ment within Bejaia metropolis (Algeria). Large scale spatial and tem- poral land-use data were used to investigate the dynamics of land-use change in this area. In this paper, we considered the case of the inter- section of Aamriw (Bejaia’s city), using discrete event simulation. This allowed us to calculate the main performance of the system with traf- fic lights and with the construction of a hopper. We present simulation results that show the validity of the queueing models in the computation of average travel times. These results allowed us to make a comparison between different versions, with traffic lights or with hopper.

An effective policy of the transport is necessary to struggle against the urban congestion. Building infrastructure is one of the most important accompanying measure to reduce a road congestion. A question has been asked: the construction of the infrastructure should it be continue, or the growing demand for mobility should it be deplaced into public transport. Optimizing of the waiting time in the intersection have advantages: save time for drivers, reducing pollution and fuel use as well as through reducing congestion and improve the road safety [10, 17]. The problem of congestion in an intersection persists and the construction of a new infrastructure was envisaged in this work. For this reasons we propose a study with the new situation. In this paper, we want to measure the traffic flow at the intersection of Aamriw in the Bejaia’s city, using discrete event sim- ulation. This allowed use to calculate the main performance of the system with traffic lights and with the construction of a hopper. Bejaia is one of the major towns of Algeria, located in the north to 180 km east of the capital Algiers, in edge Mediterranean sea. The density of Bejaia is a 481 inhabitants/km 2 in N.
