Geographic Information Systems for Highway/Sign Maintenance
Geographic Information Systems (GIS) can be a key element toward achieving improved management of all transportation facilities for municipal and state Departments of Transportation (DOT)...

Use of Geographic Information System for Transportation Data Analysis
Origin-destination (O-D) survey data have been usually applied to identify travel characteristics for transportation planning activities. Travel forecasting models are also validated against...

Transit Network Modelling?A New Approach
London's underground is one of the world's largest heavy-rail underground systems. London underground Limited (LUL) is the main rapid transit operator in London, and is financed directly...

A Microcomputer Program to Evaluate Low Cost Modifications on Urban Freeways
This paper presents a user-friendly, menu-driven microcomputer program, RAMP, for analysis and evaluation of freeway ramp junction level of service. RAMP automates the approximation procedure...

Florida's New Toll Facilities Model
Florida's Turnpike provides a system of user-financed limited access toll highways meeting important transportation needs in the State of Florida, while protecting the interests of its...

Policy Options and Highway Capacity Needs
One of the recurring criticisms levelled against FHWA's Report to Congress on the Status of the Nation's Highways is that the Report does not go far enough in examining the implications...

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...

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...

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...

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...

Determining Hours of Congestion for Urban Freeways
The concept of Hours of Freeway Congestion is a measure of effectiveness in the evaluation of freeway reconstruction scenarios. The procedure described herein estimates future traffic...

Large-Truck Safety Decision Support System
Large trucks, defined here as trucks having six or more wheels and a gross weight greater than 10,000 pounds, present a difficult safety problem to our nation's transportation system....

Tennessee's Integrated Rural Transit Microcomputer Software
The Tennessee Department of transportation (TDOT) entered into a research contract with Vanderbilt University and the University of Tennessee to develop an integrated series of programs...

Implementation of a Real-Time, Paratransit Scheduling System at DART
Dallas Area Rapid Transit (DART) implemented the GIRO/ACCES paratransit scheduling system for its HandiRides and DARTABOUT paratransit programs. HandiRides serves elderly and disabled...

Operations Simulation of Rocky Mount to Charlotte Rail Route
This paper presents the approach and findings of a study sponsored by the North Carolina Department of Transportation. The study analyzed running times of a state-sponsored 403(b) passenger...

FEDIT? User Interface for FHWA's TRAF-FRESIM^TM Model
This paper presents the FEDIT Data Input Preprocessor for FHWA's soon-to-be-released microscopic freeway simulation program - FRESIM. FRESIM (Halati, 1990, 1991) is a powerful freeway...

The Traffic Operations Control Center Simulator
As a part of a national effort to improve the operatinal efficiency of the highway network, the California Department of Transportation (CALTRANS) is developing and implementing general...

Simulating the Operation of Buses on Busways
Simulation of individual vehicles interacting within a traffic facility offers traffic operations data of detail and form uniquely suited to evaluate untried concepts or confirm yet-to-be...

Automation of Design at the New Denver Airport
This paper outlines an innovative approach to automating the roadway design process by linking design and drafting with multiple software programs and taking advantage of the strengths...

A Decision Support System for the Operation of Joint-Use Parking
A prototype decision support system (DSS) developed for streamlining the operation of a joint-use parking program is discussed. The DSS involves a combined usage of geographic information...
