Illegal overtaking is a major contributor to traffic accidents in the Kingdom of Saudi Arabia. It is the second most frequent cause of traffic accidents after speeding, and responsible for 10% of all traffic accidents in the year 2001. This paper evaluates the extent of illegal overtaking in the study area and examines the effect of time and alignment on its frequency. The study took place in t...

Currently, there are kinds of algorithms in order to detect real-time urban traffic condition. Most of these approaches consider speed of vehicles as a main metric to describe traffic situation. In this paper, we find out two important observations through several experiments. (1) In urban city, the speed of vehicles is influenced significantly by some factors such as traffic lights delay and r...

In recent years vehicular travel has been increasing at a tremendous rate. The growth of traffic volumes at many intersections has neces­ sitated many changes in the control devices employed to regulate the intersecting traffic flows. The control devices most often used when the volumes are low are stop or yield signs. At high volume at-grade inter­ sections, however, a traffic signal is requir...

For performance evaluation and dimensioning of packet-based networks, engineers need simple, efficient and realistic traffic models. The traffic volume on a packet link, observed at different time scales t, has previously been modeled as a stationary stochastic process based on the Coefficient of Variation CoV(t). In this paper we try to supply the missing information about the shape of the dis...

In this paper, we have proposed a bubble burst model by focusing on transaction volume incorporating a traffic model that represents spontaneous traffic jam. We find that the phenomenon of bubble burst shares many similar properties with traffic jam formation on highway by comparing data taken from the U.S. housing market. Our result suggests that transaction volume could be a driving force of ...

BACKGROUND In context of increasing traffic noise in urban India, the objective of the research study is to assess noise due to heterogeneous traffic conditions and the impact of honking on it. METHOD Traffic volume, noise levels, honking, road geometry and vehicular speed were measured on national highway, major and minor roads in Nagpur, India. RESULTS Initial study showed lack of correla...
