Estimation of Queue Lengths in Urban Road Networks
In this paper we present a new scheme for the surveillance of traffic state on a link of an urban road network. It is shown that measurements of traffic counts and speed values from a...
Travel Time Data Fusion in Advance
The ADVANCE project in the Chicago metropolitan area is one of several ATIS operational tests currently underway in the USA and abroad. Fusion of equipped vehicle (probes) travel time...
Filtering and Prediction on Freeways Using Markov Models
A Markov compartment model of freeway traffic flow is presented and used to derive a Kalman Filter which tracks a freeway section's density, broken down by destination. The filter is then...
Freeway Control Systems for Using Section-Related Traffic Variable Detection
Traffic control systems for freeways are described which use section-related traffic variable measurement techniques. For deriving section-related variables feature sequence of a vehicle...
Using VRC Data for Incident Detection
Most existing incident detection algorithms use inductive loops, a relatively old sensor technology that obtains data at specific points along the roadway. This paper discusses the use...
Field Implementation and Testing of a Machine Vision Based Incident Detection System
This paper contains test results of a video detection device installed in the field for over two years and the development and field deployment of an incident detection sysytems called...
Video Image Processing Application: Automatic Incident Detection on Freeways
This paper presents the results of tests carried out in the last 3 months of 1992 regarding the Automatic Incident Detection System elaborated in the INAVID project (DRIVE program). This...
Driver Assistance and Local Traffic Management, DALTM
This paper focus on some important features in the Swedish and European Road, Transport and informatic (RTI) program - the intelligent communication between road infrastructure and the...
A Prototype Real-time Expert System for Surface Street Traffic Management and Control
This paper discusses the development of a prototype real-time knowledge based expert system (KBES) to demonstrate the feasibility of assisting the operators of surface street Traffic Management...
A Dynamic Real-Time Incident Detection System for Urban Arterials?System Architecture and Preliminary Results
This study presents a system which is capable of detecting incidents in real-time and adjusting itself to traffic dynamics through the embedded learning mechanism. The entire system consists...
Rural Applications of IVHS
The Intelligent Vehicle Highway Systems (IVHS) program in the U.S.A. is understandably directed primarily toward urbanized areas where congestion is highest. Despite having somewhat less...
Rural Applications of IVHS in Minnesota
The application of advanced technologies in a rural highway environment continues to gain an increasingly significant degree of exposure within the IVHS community. As part of the Minnesota...
IVHS Transit Applications ? Rural/Small Urban Areas
The application of APTS technologies to public transportation services as found in small and medium sized communities and in rural areas is still to be explored in the United States. To...
Overview of the FAST-TRAC IVHS Program
A major new IVHS initiative, called FAST-TRAC, is taking place in Oakland County, Michigan. It originated as a bottom-up strategy for solving mobility and highway safety problems in this...
Integrating Advanced Telematics into Urban and Regional Transport Policies?Munich Greater Area Case Study
Before the background of the emerging of advanced transport telecommunication and informatics several traffic information and control systems are under development with a bottom up approach....
Seattle Area Traffic Management System Upgrade
The Washington State Department of Transportation (WSDOT) implemented the first components of this freeway monitoring and control system in 1967. A major upgrade to this system was completed...
Motorist Aid Systems ? Intelligent Roadside Controllers
Advanced technology call boxes, employing a variety of communications networks and embedded microprocessors, have brought a new level of functionality and extensibility to motorists aid...
Traffic Information and Management in a Geographically Distributed Computing Environment
This paper presents a comprehensive architecture for a geographically distributed traffic information/management system, and demonstrates the viability of such an architecture using GIS,...
Traffic Information and Driver Behavior in France
The 600 Kilometer freeway network within a 30 Kilometer radius around Paris handles 40% of the overall regional traffic volume (number of vehicles). This network is now operated by a single...
Advanced Highway Control on the Central Artery
The Boston Central Artery/Tunnel project involves highways 190 and 193, in downtown Boston, placing underground 7 miles of four to eight lane tunnels. The project, with 37 lane-miles underground,...
