Design of Impact Limiters for Waste Fuel Shipping Casks
Impact limiters are often used to control the decelerations experienced by a waste fuel shipping cask when it is subjected to the hypothetical accident condition loadings. Simplified design...
A Mesh Generator for the Modeling of Rock Discontinuities
The need to characterize a rock mass by collecting field data is receiving more and more emphasis as larger, more ambitious underground structures are being built. Yet there is a need...
Geotechnical Data Acquisition and Computerized Analysis
In 1983 and 1984, an exploratory tunnel was constructed as part of the geotechnical exploration program for two highway tunnels to be constructed for the improvement of Interstate 70 through...
Coordination of Interconnected Arterial Traffic Signals
Present analytical methods and computer programs offer capabilities of optimizing the traffic signal coordination for a series of signalized intersections. Recently, transportation research...
Endangerment Assessment in a Multilayered Aquifer Using a Microcomputer Based Transport Model
An endangerment assessment describes the types and degrees of potential hazards to public health, welfare, or the environment that may result from the release of hazardous substances into...
Computerized Construction Progress Control
In 1983 and 1984, an exploratory tunnel was constructed as part of the geotechnical exploration program for two highway tunnels to be constructed for interstate 70 through Glenwood Canyon,...
Westway - The Little Word that Killed the Big Highway
The Westside Highway Project, better known as Westway, received a construction permit on February 25, 1985 from the Army Corps of Engineers. Signed by the author, the permit was invalidated...
Three Inexpensive Land Use Allocation Techniques
The current thrust in transportation planning is to make use of manual and microcomputer techniques for providing quick-response travel estimation. In this context, matching land use techniques,...
The River Walks of San Antonio Move to Providence
At the historic heart of Providence, Rhode Island, three rivers divide the city into three areas. Nearly one mile of river corridors have been abused over the last century, resulting in...
Downtown Traffic Goes Down Under
Seattle's 1980 employment population of 124,000 is expected to jump to 150,000 by 1990. This will mean more commuter traffic and more mass transit coming into the city's...
Transit Tactics: Keeping Light Rail Moving
The Guadalupe Corridor Light Rail Transit project is a massive undertaking that will be built in segments from San Jose to Santa Clara, CA. The $372 million project involves numerous agencies...
National Urban Transportation Planning Trends and Implications
This paper explores urban transportation planning, program, and policy trends of the 1980s. Legislative and regulatory changes are also addressed. Among the planning trends discussed are...
Issues and Challenges in Transit Performance Research
Using performance indicators as a management tool in the transit industry is a developing art. Three theoretical issues have deterred progress: disagreement over definitions of efficiency...
Microcomputers and Transportation: A Look Forward
Technical development in the microcomputer industry continues to accelerate. In the next few years changes in hardware and software will occur which will be at least as dramatic as those...
Bus Maintenance Cost Control
Effective bus maintenance programs are essential for the cost-effective provision of reliable transit service. Standard tools for maintenance management include preventative maintenance...
Design and Evaluation of Small City Transit Options
Innovation in the delivery of transit service in smaller urban areas is no easy task. Budgetary matters tend to dominate the decision horizons of local transit officials. Coming up with...
