Projects like INVENT or Travolution aim at optimizing traffic flow in cities by linking vehicles and infrastructure elements using infrastructure-to-car communication technologies. Traffic lights equipped with transmitters are able to inform the approaching vehicles about the current and future state of the traffic light control. This information can be used to optimize the speed profile while ...

Wireless Sensor Networks can help to mitigate the problem of congestion in cities. Congestion occurs, when the road infrastructure cannot cope with the increased demand for the particular road segment. This paper presents a congestion control system, which uses sensors installed on the road side units to monitor the data and the cars also having the capacity to collect data from the road infras...

Intersection is a major source of traffic delays and accidents within modern transportation systems. Compared to signalized intersection management, autonomous management (AIM) coordinates the crossing at an individual vehicle level with additional flexibility. AIM can potentially eliminate stopping in due lights while maintaining safe separation among conflicting movements. In this paper, stat...

Obesity is a health problem in many developed countries and is a growing problem worldwide. In an effort to improve food choices the “traffic lights” nutritional labelling system has been developed. This system informs consumers of the relative (low, medium, high) levels of fat, saturated fats, sugar, and salt, along with energy information. There is debate over what type of thought processing ...

The cities are not static environments. They change constantly. When we talk about traffic in the city, the evolution of traffic lights is a journey from mindless automation to increasingly intelligent, fluid traffic management. In our approach, presented in this paper, reinforcementlearning mechanism based on cost function is introduced to determine optimal decisions for each traffic light, ba...

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...

Inappropriate speed is a causal factor in around one third of fatal accidents (OECD/ECMT, 2006). But are drivers always consciously responsible for their speeding behavior? Two studies are reported which show that an interruption to a journey, caused by stopping at a red traffic light, can result in failure to resume the speed of travel prior to the interruption (Study 1). In Study 2 we showed ...

BACKGROUND Two practical color vision tests were developed and validated for use in screening Air Traffic Control Specialist (ATCS) applicants for work at en route center or terminal facilities. The development of the tests involved careful reproduction/simulation of color-coded materials from the most demanding, safety-critical color task performed in each type of facility. METHODS The tests...

In recent years, Wireless Sensor Networks (WSN) have been increasingly involved in Intelligent Transportation System (ITS) optimization, especially in dynamic management of signalized intersections. This paper discusses the state of art and shows an IEEE 802.15.4 network architecture to monitor vehicular traffic flows near to a traffic light. The architecture is characterized by an innovative a...

Today’s traffic light system has a lot of limitations at road junction. The system is not flexible or in other words cannot modify on real time . The static traffic control have fixed timing for the three traffic lights “the green , yellow and red “.The cars waste a lot of fuel and surely the driver waste a lot of time . To solve and monitor the traffic light system and make it more efficient ,...
