ARRIVAL PATTERNS AND TRAFFIC FLOW CHARACTERISTICS AT SIGNALIZED INTERSECTIONS

Pedestrian Accidents with Left-turning Traffic at Signalized Intersections: Characteristics, Human Factors and Unconsidered Issues

Delay Variability at Signalized Intersections

Delays that individual vehicles may experience at a signalized intersection are usually subject to large variation due to randomness of traffic arrivals and interruption caused by traffic signal control. While such variation may have important implications for the planning, design and analysis of signal controls, currently there is no analytical model available to quantify it. This paper descri...

Estimation of Saturation Flow Rates at Signalized Intersections

The saturation flow rate is a fundamental parameter to measure the intersection capacity and time the traffic signals. However, it is revealed that traditional methods which are mainly developed using the average value of observed queue discharge headways to estimate the saturation headway might lead to underestimate saturation flow rate. The goal of this paper is to study the stochastic nature...

Analysis of the Impact of user’s Violations on the Saturation Flow Rate at Signalized Intersections

Accurate estimation of saturation flow rate is a prerequisite for accurate estimation of level of service and delays of signalized intersections. Saturation flow rate of intersections depends on many factors, including traffic behavior and culture. One of the important problems of traffic behavior in Iran is the violation of law at the physical region of intersections. The main purpose of this ...

Analysis of Traffic Flow Characteristics on Signalized Arterials

The characteristics of traffic flows on signalized arterials are examined within a cellular automata micro-simulation model. The model is used to analyze arterial throughput and travel times for given densities, coordination schemes and signal spacings. A fundamental 3-D relationship between flow, density and offsets for signalized arterials is established. It is shown, in particular, that arte...
