Arrow traffic lights are common at intersections of current urban scenes. However, existing algorithms mainly focus on recognition methods of circle traffic light. A novel system used to detect and recognize arrow traffic lights in urban scenes is proposed in the paper. Firstly, the boards of traffic light are exactly localized by image segmentation and morphology processing, then candidates of...

The objective of this study was to assess the effectiveness of freeway lighting. To achieve this, a case study on traffic accident characteristics was conducted that utilized a suburban freeway area west of Frankfurt, Federal Republic of Germany, between 1972 and 1981. The study revealed that (a) the effects of lighting on suburban freeway accident rates was positive--there was a reduction in a...

The design, development, construction and testing of an ArtificialVision controlled Traffic-Light prototype has been carried out to rule and regulate intersections. Methods, algorithms and automatons have been built up with that purpose to provide the analysis of images and decisions making at real time. The aim has been the development of an intelligent traffic-light capable of capturing the p...

Fixed cycle traffic lights decrease the throughput of traffic at intersections. Adaptive traffic light approaches dynamically change the cycle of traffic lights according to current traffic, these approaches usually improves traffic. However, it costs many resources to maintain all physical traffic lights in a city, and conventional adaptive traffic light approaches were designed for physical t...

Traffic lights are commonly known as the stop light or stop-and-go lights used as a source of signaling device in junctions around the world. It is common to position traffic lights on a certain road intersections, pedestrian crossings and other locations to control competing flows of traffic in order to enhance the smoothness of traffic flow. Traffic lights have been installed in most cities a...
