Link delay estimation using fuzzy logic

Traffic congestion poses a major problem not only in developing countries but also in developed countries due to various reasons. When subjected to traffic congestion, the travelers are likely to face delays both at intersections (road junctions) and on road links. Delays can occur due to some technical factors (traffic volume, traffic light cycle) and non-technical factors (road conditions, weather and visibility). An estimate on the level of traffic delay can be helpful in providing information to travelers for effective route selection. There are many publications on estimating traffic delays, but these are mainly based on mathematical models. Fuzzy logic has proved to be an important approach to model both technical non technical factors. This paper presents a fuzzy approach to delay estimation on road links.
