Corridor Analysis Using QRS II Route 9 Case Study
This traffic modeling project is part of a larger planning study of the Route 9 corridor through the Town of Hadley and parts of Amherst and Northampton. The Pioneer Valley Planning Comission...

Assignment Modeling with Dynamic Traffic Effects
This paper describes the new traffic assignment modeling provided by the Highway analysis component of the TRIPS package. This tackles some fundamental modeling issues regarding the time...

Validating a Citywide Traffic Planning Model
A traffic planning model can improve the public agency's ability to forecast future traffic and plan appropriate roadway intrastructure. However, the usefulness of these models depends...

The Development of a Regional GIS/Transportation Database
This paper describes the development of a prototype concept and demonstration for a geographical information system-transportation database (GIS/T) for the Regional Transportation Commission...

Better Ways to Update Trip Matrices
Updating origin-destination (OD) trip matrices usually involves considerable survey costs, so engineers are often forced to use dated OD information, which can seriously undermine the...

Using License Plate Survey Data in Transportation Planning Applications
This paper is a presentation of the methodology used by the Baltimore Regional Council of Governments to conduct a multi-faceted study for the Maryland Aviation Administration, which operates...

Trends in Digital Road Map Databases for Microcomputer Applications in Transportation
Advances in the technology and coverage of precision digital road-map database, combined with advances in the size and data processing capacity of microcomputers, are together contributing...

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...

A Method for Reviewing and Assessing PASSER II and TRANSYT-7F Signal Timing Optimization Outputs
The development of traffic signal timing plans is a common task. Some of the traffic software programs are the Arterial analysis package (AAP), the Progression Analysis and Signal System...

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...

Using the 1985 HCM, PASSER and TRANSYT in Harmony
Throughout the last decade, the City of DeKalb Engineering Division has embarked on a program to address their highly variable traffic demands with comprehensive signal system projects...

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,...

Using Interactive Simulation to Model Driver Behavior Under ATIS
This paper discusses the development and implementation of FASTCARS (Freeway and Arterial Street Traffic Conflict Arousal and Resolution Simulator), an interactive microcomputer based...

A Microcomputer Model to Estimate the Benefits of Volume Generated Auxiliary Passing Lanes on Two-Lane, Two-Way Highways
Safety and operational characteristics of rural and suburban two-lane roadways can be substantially improved by the provision of adequate passing opportunity, especially as traffic volumes...

Use of TRAF-NETSIM to Estimate the Traffic Impacts of an Urban-Resort Area Development
Urban-resort areas are concentrated visitor destination districts that are located within or in close proximity to urban areas. The combination of visitor-related and urban activities...

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...

Major Enhancements to TRANSYT-7F
TRANSYT-7F is one of the most powerfull computer programs fir traffic signal timing and traffic flow analysis. This paper describes some of the significant improvements over earlier versions...

The Integration of the Highway Capacity Manual and the TRAF-NETSIM Simulation Model
The Bureau of Traffic Operations, New York City Department of Transportation (NYCDOT) utilizes for various types of studies and capacity analyses, the 1985 Highway Capacity Methodology...
