Traditional traffic control systems based on traffic light have achieved a great success in reducing the average delay of vehicles or in improving the traffic capacity. The main idea of these systems is based on the optimization of the cycle time, the phase sequence, and the phase duration. The right-of-ways are assigned to vehicles of one or several movements for a specific time. With the emer...

This paper has investigated a novel method of using vehicle dynamic information in de-noising raw INS sensor noises. Vehicle dynamics can constitute additional observation information to be used for improving the integration performance. Since vehicle dynamic model has a low pass filter characteristic, passing the raw INS sensor measurements through it would effectively reduce the high frequenc...

This paper reports on the analysis of the signals sent by accelerometers fixed on the axles of a vehicle which passes over a bridge. The length of the bridge is divided into some parts and the transmissibility measurement is applied to the signals recorded by two following instrumented axles. As the transmissibility procedure is performed on the divided signals, the method is called Short Time ...

This paper describes the chronicle recognition problem and reports its status in the WITAS UAV project. We describe how we use the IxTeT chronicle recognition system to define chronicles (scenarios or situations), like a vehicle passing another vehicle, and how it is incorporated in the WITAS architecture. We also discuss known problems with the current system and possible directions of future ...

CONTEXT Crash fatality and injury rates are higher on rural roadways than other roadway types. Although slow-moving farm vehicles and equipment are risk factors on rural roads, little is known about the characteristics of crashes with farm vehicles/equipment. PURPOSE To describe crashes and injuries for the drivers of farm vehicles/equipment and non-farm vehicles involved in an injury crash. ...

Efficient and safe traffic control strategy for emergency vehicle can reduce its travel time and avoid secondary accident. Based on the analysis of its requirement and object, we proposed a novel control strategy at intersection according to the status of emergency vehicle, which can be divided into three parts: “approaching”, “passing “and “recovering”, Furthermore potential safety risk caused...

We present an approach for integrated decision making of vehicle agents in urban traffic systems. Planning process for a vehicle agent is separated into two stages: strategic planning for selection of the optimal route and tactical planning for passing the current street in the most optimal manner. Vehicle routing is considered as a stochastic shortest path problem with imperfect knowledge abou...
