Advances in Dry Shotcrete Technology by Means of Microsilica
During the last decade microsilica has been increasingly used to improve both wet and dry mix shotcrete. In the traditional dry process microsilica is blended in the dry mixture. Since...
Using Geographic Information Systems for Traffic Control Inventory Management
Present city traffic control inventory systems lack flexibility, user friendliness, and many have become obsolete because they were originally designed in haphazard ways - thus providing...
Network Management Using GIS
This paper is concerned with the opportunities that arise from combining digital highway networks, relational databases, GIS technology, specialist application software, and workstation...
A GIS-Based Program Management System: An Approach to Integrate Transportation Management Systems
The Intermodal Surface Transportation Efficiency Act passed by Congress in 1991 requires transportation agencies to develop six management systems that will guide state and local official...
Integration of a Municipal Pavement Management System with a Geographic Information System
This paper describes the use of a Pavement Management System (PMS), and the integration of the pavement condition data with a Geographic Information System (GIS). In June 1988, the Pavement...
GIS Application for Post Earthquake Investigation
The Post Earthquake Investigation Team (PEQIT) at the Office of Structure Design, Division of Structures, CALTRANS, has been organized since the 1971 San Fernando earthquake. It is an...
The Use of COGO/GIS in the Route 58 Corridor Development Study: A Case Study
This paper is a case study in the utilization of COGO and GIS software for the Route 58 Corridor Development Program in Southwest Virginia. The planning effort included the evaluation...
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)...
Using GIS to Define and Develop TAZ Data
GIS permits users to geographically display database information. It also can provide a common link between two or more previously unrelated databases. Increasingly, these capabilities...
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...
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...
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...
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...
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...
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...
The Permanent Traffic Count Analysis Package
The data management of traffic volume counts can be so overwhelming that limited time and effort is spent collecting and saving traffic counts. With the use of computer technology, however,...
