L'Ambiance Plaza: What Have We Learned
In April 1987, a structure called L'Ambiance Plaza collapsed during construction, killing 28 workers. The building, in Bridgeport, Conn., was being built using the lift-slab...
Reassessing the Risk Assessment
Risk assessments should help an engineer determine cost-effective remedies to environmental pollution. Unfortunately, most don't. Most assessments drastically overestimate...
Coal-Gas Conundrum
Manufactured gas from coal brought streetlights and clean cooking fuel to the late Victorian era, but a hundred years later their legacy isn't quite so beneficial. Investigators...
The Initial Exploration of Mars: Rationale for a Return Mission to Chryse Planitia and the Viking 1 Lander
The concepts behind planning a landing site on Mars are discussed. Based on the engineering constraints and the scientific objectives which will likely be imposed on the first few missions...
System Concepts for a Series of Lunar Optical Telescopes
The Lunar Telescope Working Group of the Marshall Space Flight Center (MSFC), NASA, has conducted conceptual studies of an evolutionary family of UV/optical/IR telescopes to be based on...
Plot-scale Field Experiment of Surface Hydrologic Processes with EOS Implications
Plot-scale hydrologic field studies were initiated at NASA Marshall Space Flight Center to a) investigate the spatial and temporal variability of surface and subsurface hydrologic processes,...
The New Munich Airport?Planning, Construction and Opening of a New International Turnstile Airport in Europe
The new Munich airport that began operations just recently dates back to the mid-1950. The paper discusses the general expansion plan which includes site selection; runway system planning;...
City and County of Denver Approach to Management Requirements
Construction of large infrastructure projects has become increasingly rare since the 1960's. In fact, America has not built a new airport since 1974. While sparse funding is certainly...
Traffic Data Collection: What Really Needs to be Done?
The collection of 'existing' traffic data such as the 24-hour counts, turning movement counts, driveway volumes, and vehicle classification counts near the proposed project site becomes...
A Guideline for Determining Minimum Threshold Requiring Traffic Impact Studies
Over the years, a number of localities have developed and adopted some form of traffic impact assessment (TIA) guidelines. As part of this study, an informal survey conducted showed that...
Analyzing Fast-Food Drive-Up Window Site Impacts
Peak-period queueing at a fast-food restaurant drive-up window was observed. The study found that queueing behavior equations based on random arrivals and service times overestimated the...
Access Control to Projects Via Raised Islands
When addressing driveway maneuvers at a new development, alleged ailments Must be quantified before drafting a cure. If a problem is anticipated, alternative solutions should be investigated,...
Site Impact Analysis Using the Tranplan Computer Model
As the cost of infrastructure improvements continue to spiral upward local and state governments are finding it more difficult to provide for increases in traffic volumes due to growth...
Using Computer Models in Site Impact Assessment
Use of comprehensive large area traffic models (citywide or regional) in site traffic impact assessment can greatly aid certain elements of the analysis, but may be inappropriate for other...
Computerized Transportation Planning Models for Site Impact Analysis: Precision or Complexity?
Computer based travel forecasting models are now being widely used in the analysis of the traffic impacts of proposed developments. They are commonly used to identify improvements needed...
Traffic Impact Studies for Marriott Corporation International Headquarters
This paper describes the steps taken in developing innovative traffic-related solutions to obtain approval for the Marriott Corporation International Headquarters site, which is planned...
Site Traffic Impact Analysis Process: The Developer's Perspective
