Traffic monitoring and managing in urban intelligent transportation systems (ITS) can be carried out based on vehicular sensor networks. In a vehicular sensor network, vehicles equipped with sensors such as GPS, can act as mobile sensors for sensing the urban traffic and sending the reports to a traffic monitoring center (TMC) for traffic estimation. The energy consumption by the sensor nodes i...

The analysis aims to evaluate which among traffic parameters (flows, queues length, occupancy degree and travel time) are most important in order to forecast CO and C6H6 concentrations. The study area was identified by Notarbartolo Road and bounded by Libertà Street and Sciuti Street in the urban area of Palermo. In this area, various loop detectors and one pollution monitoring site were locate...

Main goal of traffic management is the optimisation of traffic flow. This aim is based on possession of precise traffic describing data and parameters. Two dimensional traffic data acquisition becomes a research emphasis of German Aerospace Center (DLR)s Institute of Transport Research to improve these data basis. Data sources are ground based like floating car data as well as airborne remote s...

The negative effect of road traffic noise events on annoyance is now established. However, the assessment and monitoring of road traffic noise remain mainly based on energetic indicators, which are easy to handle but mask noise dynamic structure. Recent developments in dynamic road traffic modelling, and in urban sensor networks, suggest that introducing noise events in urban noise management i...

As a communication link between suburban and urban roads, terminals prevent buses from entering the cities, thus, they play an important role in improving traffic flow, reducing urban environmental pollution. Clearly, proximity of te rminals to cities will bring about environmental pollution in different forms (soil, water, air and wastewater). The current study tries to investigate the environ...

Traffic data collection is an essential issue for road-traffic control departments, which need real-time information for traffic-parameter estimation: road-traffic intensity, lane occupancy, congestion level, estimation of journey times, etc., as well as for early incident detection. This information can be used to improve road safety as well as to make an optimal use of the existing infrastruc...

Participatory sensing is a paradigm that allows each participant to sense, collect and transmit information about their surroundings to either other members in the group or to a centralized server. The information that is provided by the community of users is then combined to provide a useful service to all the participants. The focus of this work is one such participatory sensing application, ...

a pedestrian is every person who is walking, especially along or the width of a street or other place used by cars. growth, development and industrialization of societies, threatens the safety of pedestrians. increase and acceleration of vehicles and traffic, lack of road and street standards, weakness of laws or inappropriate executive guarantees, causing to insecurity and incidence of physica...

With the continuous development of computer technology and intelligent technology, more and more traditional industries complete transformation relying on the new intelligent industry. In urban traffic monitoring, traditional methods use video image acquisition equipment to collect all the data and then rely on the manpower to complete the monitoring process, not only waste a lot of artificial ...
