A controversial recreation activity is off-highway vehicle use. Off-highway vehicle use is controversial because it is incompatible with most other activities and is extremely hard on natural eco-systems. This study estimates utility theoretic incomplete demand systems for four off-highway vehicle sites. Since two sets of restrictions are equally consistent with utility theory both are imposed ...

The DARPA MoBIES Automotive Vehicle-Vehicle Open Experimental Platform [14] defines a longitudinal controller for the leader car of a platoon moving in an Intelligent Vehicle Highway System (IVHS) autonomously. The challenge is to verify that cars using this longitudinal controller provide a safe (that is, collision-free) ride. This report presents the process of verifying this particular contr...

Convoy driving on highways is a desirable behavior which reduces the risk of highway accidents and makes traffic faster and more fluent. Recent technologies, such as intelligent cruise control devices explicitly facilitate convoy driving by providing a fully automated means for following the previous vehicle. Participating in a convoy, however, requires compromises from the vehicles, such as sl...

Intelligent traffic surveillance systems are assuming an increasingly important role in highway monitoring and city road management systems. Recently a novel feature was proposed to improve the accuracy of object localization and occlusion handling. It was constructed on the basis of the strong shadow under the vehicle in real-world traffic scene. In this paper, we use some statistical paramete...

The systems in which information and communication technologies and systems engineering concepts are utilized to develop and improve transportation systems of all kinds are called “The Intelligent Transportation Systems (ITS)”. ITS integrates information, communications, computers and other technologies and uses them in the field of transportation to build an integrated system of people, roads ...

Automatic symbolic traffic scene analysis is essential to many areas of IVHS (Intelligent Vehicle Highway Systems). Traffic scene information can be used to optimize traffic flow during busy periods, identify stalled vehicles and accidents, and aid the decision-making of an autonomous vehicle controller. Improvements in technologies for machine vision-based surveillance and high-level symbolic ...

In this paper we describe an approach to detect and predict the driving trajectory of a preceding vehicle on highway. In particular, we focus on detecting and predicting the changing lane intention and action of the preceding vehicle. Our algorithm employs SVM for driving pattern recognition by integrating two different cues: motion cue and appearance cue, which is trained on two class feature ...

Collaborative driving is an important sub-component of Intelligent Transportation Systems (ITS) and it strives to create vehicles that are able to cooperate in order to navigate through urban traffic by using communications. In this paper, we present an overview of different architecture from the field of artificial intelligence and robotic systems, related to collaborative driving, and analyze...

A case study of the difficulties encountered in the design of hierarchical, hybrid control systems is presented. As our example we use the Intelligent Vehicle Highway System (IVHS) architecture proposed for vehicle platooning, a system that involves both continuous state and discrete event controllers. We point out that even though conventional analysis tools suggest that the proposed design sh...

The application of Mobile Ad Hoc Network (MANET) technologies to Vehicular Ad Hoc Networks (VANETs) in the service of Intelligent Transportation Systems (ITS) has brought new challenges in maintaining communication clusters of network members for long time durations. Stable clustering methods reduce the overhead of communication relay in MANETs and provide for a more efficient hierarchical netw...
