Prediction of Link Travel times in the Context of Nottingham’s Urban Road Network
Traffic congestion is becoming a serious environmental threat that must be resolved quickly. Traditionally, travel information systems have been specific to a particular mode of transport. For instance, traffic information (road conditions broadcast) has been directed at drivers. Instead, travel information systems are now being developed which incorporate route guidance systems to divert drive...
متن کاملRoad Expansion, Urban Growth, and Induced Travel: A Path Analysis
Claims that roadway investments spur new travel and thus fail to relieve traffic congestion, known as induced demand, have thwarted road development in both the United States and abroad. Most past studies point to a significant induced demand effect. This research challenges past results by employing a path model to causally sort out the links between freeway investments and traffic increases, ...
متن کاملUrban Road Travel Time Prediction based on ELM
The Travel Time Prediction (TTP) is an important element in the study of the advanced transportation guidance system and control system. In this paper, an advanced method with Extreme Learning Machine algorithm(ELM) has been discussed by analyzing the various travel time prediction method. The feasibility and advantages of Extreme Learning Machine in travel time prediction has been studied, and...
متن کاملModeling Travel Time Distributions on a Road Network
In transportation networks, it is more useful to think of costs on links as travel times as opposed to distances. Furthermore, while distances are usually constant, deterministic values, between nodes, travel times often vary substantially, as a result of incidents, road conditions, weather, traffic volume and drivers' preferences, among others. Recent research has developed a variety of algori...
متن کاملDeriving Link Travel - Time Distributions via Stochastic Speed Processes
W derive an analytical expression for the cumulative distribution function of travel time for a vehicle traversing a freeway link of arbitrary length. The vehicle’s speed is assumed to be modulated by a random environment that can be modeled as a stochastic process. We first present a partial differential equation (PDE) describing the travel time distribution and obtain a solution in terms of L...
