Conditional Priority at Controlled Intersections to Improve Public Transport Punctuality
The market share of public transport depends highly on the travel time ratio to private transport. The public transport travel time includes among other elements waiting times at stops...
A Sketch is Worth a Thousand Rule Traces
The paper presents techniques for augmenting communication among building designers by providing (1) interdisciplinary explanation facilities to visualize and annotate CAD models, such...
Synthesis of Traffic Signal Timing for the Highway Capacity Manual Planning Analysis
The 1985 Highway Capacity Manual (HCM) provides a technique to analyze the operation of signalized intersections. The Highway Capacity Software (HCS) is a microcomputer package that faithfully...
Graphical Representation of Signal and Stop Sign Control Warrants Combined with Level of Service Estimates
An insolated intersection is usually controlled by either signals or stop signs. The choice between these two trafic control devices requires an engineering study which typically examines...
Real-Time Delay Measurement and Intersection Analysis System
Two intersection delay measurement approaches are developed, and a framework for a real-time traffic signal data collection and intersection operational analysis system is presented. The...
An Expert System Analysis of the Signal Operational Analysis Package Results
An expert system is a type of artificial intelligence program that captures the human knowledge which is involved in making a decision. Expert systems are very suitable for solving problems...
Development of Self-Organizing Traffic Control System Using Neural Network Model
This paper is concerned with developing a self-organizing traffic control system using a neural network model, a multilayer network model. The neural network inputs the control variables,...
The Wizard of Helpful Intersection Control Hints
The methodology for making traffic control decisions is the subject of this paper. There exists a body of knowledge supporting a sound decision making process, but it requires the use...
An Expert System for Stop-Controlled Intersection Design
In 1915, the first stop sign was installed in Detroit, Michigan, but until now, there was still no one coordinated body of knowledge which would dictate design and analysis requirements....
A CADD Program for Simulating Turning Vehicles
The turning capability of one or more 'design' vehicles and their swept paths has a significant influence on the layout of transportation facilities such as roadway intersections, parking...
Driving Under a Construction Site
Throughout the summer of 1992, vehicles passed unimpeded through one of the most heavily traveled intersections in Los Angeles County as construction proceeded on a concrete light-rail...
Machine Vision Based Traffic-Adjusted Intersection Signal Control
This paper describes some of the available machine vision systems and how they can be effectively used for traffic control at an intersection. A set of rules have been defined which make...
ICU?A Method of Analyzing Signalized Intersections
There is a need for decision makers, developers and the public to understand the potential traffic impacts of site development. Signalized intersection operations are a primary indicator...
The Isolated Signalized Intersection as a Mitigation on a High-Speed Highway
A concentrated 'leap-frog' type development is commonly proposed as it offers the opportunity to organize an extensive living-recreation orientated site with low to modest land costs....
Circulation Issues and Impacts?Corridor Redevelopment Santa Ana, CA?A Case Study
The Bristol Street Corridor Plan provides the framework for future redevelopment of a 3.0-mile section of the Bristol Street corridor in the central portion of the City of Santa Ana, California....
Intersection Air Quality Analysis
Methods of carbon monoxide concentration estimation at or near intersections have recently undergone scrutiny with resulting debate on the proper and accurate ways to make these estimates...
Modeling Guideline for Air Quality Analysis of Intersections
Model evaluations have been performed testing eight different models for the ability to estimate carbon monoxide near intersections. These evaluation results along with the need for updated...
Integrating Traffic and Air Quality Modeling Techniques to Predict Pollutant Concentrations Near Intersections
Many cities are considering transportation management measures and/or tailpipe emission controls to reduce the pollution associated with traffic congestion. A major difficulty is the expensive...
An Advanced First-Order Method for System Reliability
This paper proposes an iterative first-order method for accurate estimation of the joint failure region of two nonlinear limit states. Current methods use either a first-order approach...
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...
