Fully-Distributed Control of Signal Networks
A fully-distributed real-time control strategy is described for signalized networks. The signals make compatible, simultaneous decisions about cycle length, offset and splits, without...
Cars: A Demand-Responsive Traffic Control System
This paper presents a demand responsive traffic control system for networks based on improvements from a combination of OPAC and ACTS approaches. The system has shown clear advantages...
Optimal Ramp-Metering Control for Freeway Corridors
The paper discusses an optimal ramp-metering control model wherein a corridor is discretized into small road sections, with density as the state variable and ramp metering rates, the control...
Application of Control Theory to Regulate Traffic Flow on Periurban Ringways
Two on-ramp metering strategies are compared by a simulation study for the Boulevard Peripherique in Paris. The first one is a local strategy, based on linear feedback control theory....
Potential Freeway Capacity Effects of Advanced Vehicle Control Systems
Intelligent Vehicle/Highway Systems (IVHS) are intended to improve the productivity (capacity) and safety of the road transportation system. The PATH program has placed a stronger emphasis...
Institutional Barriers to IVHS Introduction
The introduction and application of Intelligent Vehicle/Highway Systems (IVHS) will help to mitigate the adverse safety, environmental, and economic impacts of traffic congestion on selected...
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...
Traffic Control System on the Hanshin Expressway
The Hanshin Expressway Public Corporation, Osaka, Japan has been developing and operating its automated traffic control system since 1969. This paper deals with the latest version of the...
Safety of IVHS: Methods for Determination of Accident Levels for AVCS-1 Devices
This paper discusses ways in which the safety impact of Intelligent Vehicle/Highway Systems (IVHS) devices can be estimated by interpreting existing statistics. This is needed at many...
Taming the Silicon Steed?Perceptions of Risk
This paper draws from contemporary research in the psychological literature to argue that transportation engineers and decision makers should consider the issue of perceived risk when...
The Contribution of Dynamic Route Guidance and Information Systems to More Efficient Traffic Management
The environmental and traffic-related problems expected as a result of the continued increase in motorization require new solutions if our towns and cities are to survive and their attractiveness...
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...
Fault-Tolerant Computing Architecture for MF 88 and MP 89 Rolling Stock
For several years now, the French and the foreign railway industries have witnessed the development of a new generation of on-board computer systems for rolling stock. It mainly features...
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...
Case History of the Point Roberts Marina
This paper presents a fifteen year history of the design performance of the Point Roberts Marina. The 1,000 berth small craft harbor is located on the Strait of Georgia, immediately north...
Operation and Maintenance Plan for Marinas
A operation and maintenance (O&M) plan for marinas is presented to describe the process and establish basic parameters that can be used as guidelines to more comprehensive site-specific...
Organisation Structure and Control
With today's rapidly changing world economies and a variety of other pertinent factors, the euphoria of the past few years is fast dwindling and a professional approach in...
Avalon Harbor: Example of a Successful Destination Harbor
Avalon Harbor, which is located on the southeast side of Catalina Island approximately 25 miles (40 km) off the coast of Southern California, is an excellent example of a destination harbor...
Simplified Tidal-Flushing Model for Small Marinas
This paper describes the development and application of a new water quality screening model - STEAM (Simplified Tidal Embayment Assessment Model). This model simulates the first-order...
