A Catastrophe Theory Approach to Freeway Incident Detection
This paper discusses an approach to incident detection on freeways that classifies traffic conditions at a single station rather than by comparing conditions at adjacent stations. The...
A Low Pass Filter for Incident Detection
A new algorithm for automatic incident detection was developed after observing that existing algorithm performance can improve if detector data are filtered before use. The new algorithm...
Automatic Incident Detection Using Image Processing Techniques: A Specific System Used in INVAID
INRETS together with other partners, within the European DRIVE program framework is working on developing a system able to detect incidents on motorway by processing video images (Jref....
A Distributed Real Time Knowledge-Based System Using Video Image Processing for Junctions Automatic Incident Detection
The scope of the INVAID project (in the European DRIVE program) is to build an automatic incident detection system which incorporate the image processing capabilities. In the urban aspects...
A Real-Time Traffic Diversion Model: A Conceptual Approach
The development of a real-time traffic diversion control system for integrated freeway and arterial networks, as part of the most currently envisioned Intelligent Vehicle/Highway System...
A New Approach for Real-Time Prediction of Traffic Demand-Diversion in Freeway Corridors
An adaptive method is developed for real-time prediction of demand and diversion of traffic flow at on-ramp areas of freeway corridors. The prediction method explicitly treats the time-variant...
Dynamic Stochastic Equilibrium Model in Multiple Vehicle Type Transportation Networks
In this study, a multi-vehicle type dynamic stochastic user equilibrium model (called MDSUE model for abbreviation) is developed. By using MDSUE model, the prediction of departure rates...
Dynamic Estimation of Freeway Demand Patterns and a Stochastic Programming Approach to Freeway Ramp Metering
Controlling the rate at which vehicles are allowed to enter a freeway from the freeway's on-ramps has become a standard method for reducing the impact of both recurring and...
Effectiveness of Real-Time Information Strategies in Situations of Non-Recurrent Congestion
The effect of real-time information on the performance of a traffic commuting corridor in situations of non-recurrent congestion is studied using a dynamic simulation model. Non-recurrent...
Experiments with Formal Specifications on MAGGALY
Until lately, safety functions for automatic train driving systems have mostly been implemented with classical techniques such as relays, way circuitry and, more recently, electronic devices....
Safety Microprocessors in Guided Ground Transport
The use of microprocessors performing safety tasks such as Automatic Train Protection systems made more difficult their safety-worthiness assesment. In this paper we will first examine...
Simulation of a Vehicle Platoon Control System for Automatic Highway Using the Fuzzy Control Concept
This paper discusses the concept of the longitudinal control of vehicle platoons on the highways. The paper discusses the simulation of vehicles with non-linear properties, such as air...
Vehicle Lateral Guidance Using a DSP Based Vision System
A practical real-time vision system system which uses a digital signal processing chip to obtain a tracking error for lateral guidance of vehicles at highway speeds is presented. Minor...
Minnesota Department of Transportation Experience in the Application of Advanced Traffic Management Systems
The Minnesota Department of Transportation (Mn/DOT) began deploying Advanced Traffic Management Systems (ATMS) in the early 70's. The Interstate 35W just south of the Minneapolis...
Academic Research Efforts in the GuideStar IVHS Program
The Minnesota Department of Transportation (Mn/DOT) and University of Minnesota officials, realizing that Minnesota was among the leaders in both research and implementation of advanced...
Advanced Traveler Information Systems-The Vision Beyond
This tutorial describes the author's vision of a mature Advanced Traveler Information System (ATIS), the individual modules, including public transportation, of the system,...
Burns Waterways?Boat Capacity Study
The results of a boat capacity study for the Burns Waterway located in the city of Portage, Indiana, close to the southern tip of Lake Michigan are presented. More than 650 recreational...
Avalon Harbor Utilization
Avalon Harbor is a destination resort harbor which serves the Southern California boating community and recreation public. The harbor is a roadstead mooring in a partially protected cove....
Aircraft Traffic Mix Analysis: Damage Factors and Coefficients
Historically, traffic mix analyses have been based upon the use of the critical or most damaging aircraft. The damage effects of other aircraft are either ignored or empirically incorporated...
