Introduction to How to Provide Accurate and Robust Traffic Forecasts Practically?
With the development of our modern cities, growing traffic problems adversely affect people’s traveling convenience more and more, which has become one of the most crucial factors considered in urban planning and design in recent years. Urban traffic congestion is a severe problem that significantly reduces the quality of life in particularly metropolitan areas. However, frequently constructing new roads is not realistic and untenable in social and economic aspects. In the effort to deal with this intractable problem, so-called intelligent…
Introduction to Active Traffic Management as a Tool for Addressing Traffic Congestion
Recurrent and non-ecurrent congestion in urban areas continues to be a major concern due to its…
Introduction to Deploying Wireless Sensor Devices in Intelligent Transportation System Applications
A recent study by the UK Government’s Office of Science and Innovation, which examined how future intelligent infrastructure would evolve to support transportation over the next 50 years looked at a range of new technologies, systems and services that may emerge over that period (UK DfT, 2006). One key class of technology that was identified as having a significant role in delivering future intelligence to the transport sector was wireless sensor networks and in particular the fusion of fixed and mobile networks to help deliver a safe, sustainable and robust future transportation system based on the better collection of data, its…
Introduction to Investigation of Measurement for Travel Time Variability
Congestion has grown over the past two decades making the travel time highly unreliable. The Federal Highway Administration (FHWA), US Department of Transportation (USDOT) indicated travel time as an important index to measure congestion. Frequent but stochastic, irregular delays increase the challenge for people to plan their journey – e.g. when to depart from the origin, which mode(s) and route(s) to use so the on-time arrival at the destination can be ensured. In addition to average travel time, the reliability of travel time has been…
