Traffic congestion in road networks is one of the main issues to be addressed, also vehicle traffic congestion and monitoring has become one of the critical issues in road transport. With the help of Intelligent Transportation System (ITS), current information of traffic can be used by control room to improve the traffic efficiency. The suggested system utilize technologies for real-time collect...

With the rapid development of urban traffics, recently many big cities have established lots of modern traffic networks extended in all directions, but there are still some severe problems caused by traffic congestions and traffic accidents. So for improving these unsatisfactory states in the urban traffic, inspired by the immune cooperative phenomenon from the biologics, firstly the regional t...

In order to control urban traffic with model-based control methods, a proper traffic model is very important. This traffic control model needs to have enough descriptive power to reproduce relevant traffic phenomena, and it also has to be fast enough to be used in practice. Therefore, macroscopic urban traffic flow models are usually applied as control models. These models are normally sampled ...

The objective of this paper is to devise a way to facilitate the use of fixed air monitors data in order to assess population exposure. A weighting scheme that uses the data from different monitoring sites and takes into account the time-activity patterns of the study population is proposed. PM2.5 personal monitoring data were obtained within the European EXPOLIS study, in Grenoble, France (40 ...

An important aspect of area-wide traffic calming concepts is the integration of major urban roads, because 70 to 80 percent of all urban accidents occur on major roads. Traffic calming which is primarily based on the locational shift to such main thoroughfares is socially injust, because -in spite of all disturbances on those streets about one quarter of the urban population live there. Social ...

Sustainable development is one of the themes of the world today. Considering growing urban traffic problems and urban environmental problems, developing sustainable transport is particularly important. Based on the urban traffic sustainable development theory, an evaluation index system of traffic sustainable development is built using analysis method and testing methods of index system. Then a...

The safety of river-crossing tunnels is an important aspect of urban road traffic systems. Previous studies concerning traffic safety mainly focused on urban roads. Given the absence of a number of variables, such as speed and real-time traffic volume, in traffic accident databases, the traffic safety of urban river-crossing tunnels has rarely been studied. This study used the microscopic traff...

Automatic incident detection is becoming one of the core tools of urban traffic management, enabling more rapid identification and response to traffic incidents and congestion. The existing traffic detection infrastructure within many urban areas (often installed for traffic signal optimisation) provides urban traffic control systems with a near continuous stream of data on the state of traffic...

Current mobile phones are becoming important platforms that serve the ubiquitous sensing and communication needs of people [29, 55]. The sensing and communication modules on mobile phones are usually developed to provide location and context-aware services. Real-time urban traffic conditions are critical to wide populations and serve the needs of many transportation dependent applications. This...

Vehicles provide an ideal platforms for a plethora of emerging applications such as networked gaming, multimedia content delivery and urban sensing. Cars have no power constraints and they can be instrumented with high end computational units and graphic devices. The deployment at scale of urban vehicular systems, however, require a careful design able to consider challenges across several doma...
