Positively Not Pedestrian
An elaborate pedestrian and bicycle bridge in Eugene incorporates a number of innovative engineering features to create an aesthetically pleasing structure to complement the surrounding...
New Uses for Old Bridges
As historic bridges age, they are often rendered useless by modern load requirements and codes. Many had been abandoned or demolished. In 1991, however, the ISTEA created new provisions...
A Computerized Methodology for Conducting Pedestrian Gap Studies
this paper will detail recent improvements with the procedure the New York City Department of Transportation utilizes when conducting Pedestrian Gap Studies. These improvements were made...
ISTEA Enhances Transportation
The aim of the Intermodal Surface Transportation Efficiency Act (ISTEA) of 1991 was to integrate communities with transportation programs. Engineering professionals now have the responsibility...
Computer-based Building Design and Pedestrian-level Wind Conditions
Knowledge based computer system has been developed for the evaluation of wind conditions around buildings at pedestrian level. This paper concentrates on two major components of the system,...
Infrared Detector Developments
Modern road transport systems rely on information from sensors to operate safely and efficiently. The sensors are typically used to provide vehicle counting, occupancy, speed measurement...
A Model for Analyzing Large Transportation Networks on a Microcomputer
The Pedestrian Level of Service (PEDLS) model combines the best features of spreadsheet programs - their ease of use for inputting data and producing printed output reports - with the...
Effective Pedestrian Safety Programs
Pedestrian fatalities account for 16 percent of all highway-related deaths and about 129,000 pedestrians are involved in accidents each year. Analyses of pedestrian accident data and determining...
Safety Impacts of Installing Pedestrian Crosswalks
At-grade pedestrian crossovers (PXO's) have been installed at about 700 locations in Metropolitan Toronto to assist pedestrians in crossing busy streets at minimal delay to...
Human Factors: The Problem with the Problem
Human behavior in the highway transportation system is prone to error and has basic limitations. It is modifiable within those basic limits. Most often we focus attention on the behavior...
British New Towns and the Civil Engineer
