Improving Safety and Traffic Conditions on National Roads Passing through Towns without Bypass

Abstract Traffic congestion spread beyond major cities and expands on national roads that connect various sites of interest. Many of these roads pass through the towns whose inhabitants must endure the negative consequences of transit traffic: increased delays and pollution levels, decreasing pedestrians safety. Thus, it is necessary to find a balance between road users’ wishes (drivers and pedestrians) in order to reduce vehicles transit time and increased pedestrians safety. The study of road traffic is a complex problem, difficult to analyze by analytical methods and therefore it is suitable for computer simulation. Using advanced simulation software, the paper investigate the influence of traffic intensity, pedestrian crossings, traffic signals timing and traffic signals coordination parameters through microsimulation of traffic on an important national road that transit a Romanian town without bypass. The proposed solutions can lead to reduced vehicles transit time, of air pollution and an increase of pedestrians safety.
