An Application of Advanced Technologies for Freeway Traffic Management?An Indiana Case Study
The Indiana Department of Transportation is in the process of implementing an electronic surveillance and control system on the Borman Expressway (I80/94). This paper presents a summary...

Stereo Vision with Scan-Line Cameras for Intrusion Detection on L.R.T. Tracks
In this paper we present a new method for the detection of intrusions by means of stereo vision in order to infer 3D information from two linear sensors. This method can be used for security...

Two Approaches for Characterizing Images of Rail Surface Flaws
Rail surface flaws can be removed by grinding to improve the life of rail and provide a safe, smooth running surface. To avoid time consuming and costly visual inspection in the determination...

Automated Analysis of Pavement Distress Data
A system model that can be used for the analysis of pavement distress data collected by various visual devices (e.g. photographic film) is presented. The models operate at two levels:...

Pavement Image Processing Using Neural Networks
This paper discusses the potential for employing neural network models in the pavement image interpretation and classification stage of an automated pavement condition evaluation system....

Design of HCM Signal Timings Using Signal Expert
While computer implementations of the procedures for evaluating the operation of traffic signalized intersections are receiving widespread use, these implementations are still primarily...

Design and Evaluation of Multi-Band Progression Schemes
Multiband is a new arterial progression scheme that has the capability to assign each directional road section with an individually volume-weighted band. The method offers to the traffic...

An Application of Expert Systems to Traffic Signal Control
Signal Control at Isolated Intersections (SCII) has been developed to emulate an adaptive controller using AI technology. It is an application of expert systems to the real-time traffic...

Bus Pre-Emption: A Real Time Control Strategy for Privatized Transit Operation
Bus pre-emption strategies are designed to provide priority to transit buses over passenger cars for urban travel. A comparative analysis of a proposed suburban bus service for regular...

Advanced Software Design and Standards for Traffic Control
Improved traffic traffic management and control systems are widely reported to be cost effective investments [Neudorff 88, Kessmann 85]. However, many hardware and software obstacles have...

Fiber Optic Communication Systems for Freeway Traffic Management
The communication requirements of freeway traffic management systems (FTMS) can be effectively met by systems which utilize fiber optic cables and associated equipment. This paper discusses...

Traffic Signals and At-Grade LRT
Light rail systems are making a comeback in American cities. This often generates local concerns about traffic congestion. This paper discusses the application of computer technology to...

Infrared Detector Developments
Modern road transport systems rely on information from sensors to operate safely and efficiently. The sensors are typically used to provide vehicle counting, occupancy, speed measurement...

Dynamic Route Guidance?The Drive Project CAR-GOES
The DRIVE project CAR-GOES has studied strategies for integrating road traffic management and central systems for dynamic route guidance and traffic signal control. This paper summarises...

Video Image Processing for Toll Operation Evaluation
Toll motorway companies are very much concerned with toll plaza operation and its appreciation by customers. The problem is two-fold: define a desired level of service (queue lengths,...

Car Wars?The DOTs Strike Back
HNTB is developing integrated computer systems utilizing standard hardware and software platforms coupled with graphical user interfaces for traffic management systems (TMS). Rapid, user-friendly...

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 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...
