Conventional traffic light control systems are based on fixed time intervals of the traffic lights. These conventional fixed traffic light controllers have limitations and are less efficient because they use a hardware, which functions according to the program that lacks the flexibility of modification and adaptation on a real time basis. Thus due to the fixed time intervals of green and red signals...
Currently, most automatic traffic incident detection systems rely heavily on data collected from fixed sensors such as inductive loop detectors and surveillance cameras. However, fixed sensors are difficult to install and maintain. Moreover, it is quite costly to deploy a large number of fixed sensors to cover a broad area. It is potentially more efficient to use vehicles as mobile sensors to collect...
PRISMA solutions (Austria) together with TraffiCon (Austria) have developed an intelligent transportation system (ITS) for a virtual smart city called VENUS for the new Research Park of the University Žilina (Slovakia). Besides a network and location-reference manager VENUS also provides infrastructure management (sensors, traffic lights, variable message signs, etc.) as well as complex traffic message...
According to road accident data, majority of the accidents occur at night. Visibility at night is major issue for safe driving. Therefore negligent drivers continue to use high beam even though oncoming vehicle is suspected. These high beams create glare for oncoming drivers and cause temporary blindness. To solve this problem, nighttime vehicle detection holds a great importance. This paper reviews...
Due to the extreme fast movement of traffic in the busy localities, the cases of road accidents are increasing day by day. Traffic Control Board made different speed limit for different places to limit the speed, but it is not possible to always monitor the infringements manually due to several factors.
In this paper the authors present an approach to the interpretation and distribution of geo-referenced information about road events for the purpose of road traffic shaping in the INSIGMA system. Particular focus was paid to the architecture and development of Registration, Distribution and Displaying Road Information on Variable Message Signs that implements the proposed mechanism. Created subsystem...
This paper demonstrates the automated traffic surveillance without any human intervention. The aim of this paper is to detect the traffic density and to work according to the traffic density. The traffic signal is structured with the camera which takes the snap of the road and the density is identified. Hence by this method the traffic is analyzed and the lights are transferred according to the traffic...
With the global trend towards urbanization, traffic control becomes an especially important problem. Existing ‘intelligent’ traffic control systems are usually of large scale, requiring high computation resources cost, especially equipped roads and traffic lights, and necessary legislations from governments. In this paper, we propose a framework resolves these issues by utilizing the processing power...
Reducing traffic congestion and improving the efficiency of urban vehicular mobility are widely recognized as central objectives for smart cities. In particular, given the economic/time costs of developing an infrastructure for traffic monitoring and surveillance, there is growing interest in the exploitation of V2V communication technologies to foster new forms of peer-to-peer cooperation and to...
This paper introduces a system for chaotic traffic control; the proposed system is a simple, sophisticated and robust version of the Intelligent Traffic Light Flow Control System Using Wireless Sensors Networks proposed by Khalil M. et al. The proposed system adopts a simple approach by adding more Traffic Sensing Nodes [TSN] and distributing them in a matrix layout covering the road bed. In addition...
Vehicular travel is gaining importance everywhere, particularly in large urban areas. The current technologies that support vehicular travel like wired sensors, inductive loops, surveillance camera etc., are expensive and also require high maintenance cost. Further the accuracy of these devices also depends on environment conditions. The typical traditional approaches attempt to optimize traffic lights...
This paper describes a microscopic traffic simulation tool for assessing the performance of ITS traffic and vehicle control systems. The scope of simulation is very broad. The traffic network is simulated in microscopic scale with nanoscopic components being available as well. The vehicles can be simulated down to basic physical properties including throttle and brake settings, fuel consumption and...
Wireless technologies can help solve traffic congestions in urban environments, where road infrastructures develop slower than the sometimes exponential growth in the number of cars in traffic. We present a traffic control and congestion avoidance system developed over a vehicular ad-hoc network created between the cars in traffic and the road infrastructure. We propose a solution for monitoring traffic...
Wireless technologies can help solve traffic congestions in urban environments, where road infrastructures develop slower than the sometimes exponential growth in the number of cars in traffic. We present a system for traffic control and congestion avoidance. The system monitors traffic using cars acting as data collectors. It aggregates the monitoring data into a traffic model, further used by cars...

In this paper we present an intelligent traffic signals control system based on a wireless sensor network...
To improve performance of traffic signal control system in urban area, a novel method is proposed in this paper. The roads, vehicles and the traffic control systems are all modeled as intelligent agents. Wireless communication network provides the possibility of the cooperation of vehicles and roads. Based on all the information from vehicles and roads, a traffic control policy can be planned online...
Traffic congestion has become a major problem in today's society. It may cause a great waste of material and human casualties. We think the fixed-time-state traffic light control scheme is one important reason. An intelligent traffic light control scheme is necessary in order to give a solution to this problem. The paper proposes a model to describe a road cross. In terms of dynamic and real-time...
The availability of several Advanced Driver Assistance Systems has put a correspondingly large number of inexpensive, yet capable sensors on production vehicles. By combining this reality with expertise from the DARPA Grand and Urban Challenges in building autonomous driving platforms, we were able to design and develop an Autonomous Valet Parking (AVP) system on a 2006 Volkwagen Passat Wagon TDI...
The application of GPS probes in traffic management is growing rapidly as the required data collection infrastructure is increasingly in place in urban areas with significant number of mobile sensors moving around covering expansive areas of the road network.
