The main necessary functions to manage the traffic on the movement area and the airspace around an airport are surveillance, control, routing and guidance. 1 Routing is often also termed planning. Today these functions are carried out manually by the controller in the tower and in the apron. But automatic assistance is becoming more and more important with increase of traffic flow in order to r...

In Indian four-lane express highway, millions of vehicles are travelling every day. Accidents are unfortunate and frequently occurring in these highways causing deaths, increase in death toll, and damage to infrastructure. A mechanism is required to avoid such road accidents at the maximum to reduce the death toll. An Emergency Situation Prediction Mechanism, a novel and proactive approach, is ...

Street-parking vehicles cause many problems in urban traffic situation: blinds area, traffic congestions, and so on. Detection method of street-parking vehicles are proposed. The proposed method is based on epipolar-plane image (EPI) analysis. First, our proposed method detects edges in EPIs by applying Hough transformation. By computing depth variation from slope of detected edges, street-park...

In this extended abstract, I present an overview of IVHS-related research recently initiated at the University of Michigan Artificial Intelligence Laboratory. Our ultimate goals in this effort are to further the technology underlying decision support for both individual drivers and traffic management centers within a variety of decision contexts, including routing, scheduling, and control of si...

Priority rules are one of the most promising approaches to aircraft conflict resolution. This paper deals with the problem of priority assignment in autonomous Air Traffic Management with imperfect trajectory prediction. A robust solution is presented that relies on onboard traffic pattern classification using a data base common to all aircraft. The method allows reaching a common consensus in ...

Stereo Vision is a key technology for modern Driver Assistance Systems aiming at increased traffic safety and driving comfort. The opportunity to directly measure the depth of pixels and objects is crucial for understanding the current traffic situation and to detect risky situations. Inspired by results obtained in photogrammetry, we developed a stereo vision system that has recently been intr...

In this paper a recent variable anticipation cellular automata model for single-lane traffic flow is extended to analyze the situation of free and congested flow in the Highway from Mexico City to Cuernavaca. This highway presents free flow in standard days; but in the returning day of long weekends or holidays it exhibits congested flow and in rush hours jamming appears. We illustrate how our ...

Describes the design and implementation of an intelligent traffic lights controller based on fuzzy logic technology. A software has been developed to simulate the situation of an isolated traffic junction based on this technology. It is highly graphical in nature, uses the Windows system and allows simulation of different traffic conditions at the junction. A comparison can be made between the ...

Describes how to compute the optimal extension time that will add to the fixed time control system. The system has been developed to simulate isolated traffic junction with respect to the situation of its backward and forward neighbours based on fuzzy logic. By using MATLAB (Fuzzy Logic Toolbox) we also show the simulation and the results obtained from the system. A comparison can be made betwe...
