The Energy Policy Act (EPACT) has a goal of replacing ten percent of transportation petroleum fuel with alternative fuels and replacement fuels by the year 2000, and 30 percent by 2010. Sections 501 and 507 of EPACT encourage and mandate use of alternative fueled vehicles (AFVs) in fleet applications. In particular, Section 501 mandates that certai

Since 1992 the CNG trash trucks have accumulated more than 60,000 miles in regular service in the New York City fleet. Overall, their performance has been excellent. The Alternative Fuels Data Center (AFDC) at the Department of Energy's National Renewable Energy Laboratory (NREL) has been accumulating refueling and maintenance data on these trucks

This discussion paper addresses the concepts involved in defining the functional area of an intersection. The elements which comprise the upstream functional area are identified; dimensions of the upstream area exclusive of queue storage, are given for various speeds. The various approaches for defining the downstream area are also presented.

METAR-Meteorological Aviation Routine Weather Report; TAF--Aerodrome Forecasts. This presentation provides explanation on new METAR/TAF Codes to become effective July 1996. Prepared ca. 1996.
The graying of America is resulting in a larger proportion of older individuals in the population. Recent transportation surveys show that an increasing number of older individuals are licensed to drive and that they drive more than their same age cohort a decade ago. These trends necessitate increased study of their potential highway safety proble

This report is a historical performance review of epoxy-coated reinforcement. The information in this report is presented in chronological order starting from the early 1970's, when the first bridge with epoxy-coated reinforcement was built, and ending with the presentation at the 1993 TRB sessions, where findings from the latest research investiga

This research effort was motivated by the desires of planning agencies to seek alternative methods of deriving current or base year Origin-Destination (O-D) trip tables without adopting conventional O-D surveys that are expensive, time consuming and labor intensive. This study had two objectives: (t) to conduct a review of existing approaches and m

This report represents evaluations of Data Link products and services in a simulated aviation operation. The study addresses key issues related to alerting schemes for Data Link messages, positioning of Data Link displays, and mode of presentation of Data Link messages. The comparison of response times of two alerting schemes, a nondistinctive aler

This report documents the results of the "Investigation of Fuselage Structure Subject to Widespread Fatigue Damage" contract. The primary program objective was to obtain data on airplane fuselage structures subject to multiple site damage (MSD) in an environment that reflects typical commercial jetliner manufacturing and operating conditions. The p

California has adopted an aggressive plan to bring the state into compliance with national ambient air quality standards. California's strategy includes strict emission standards on mobile and stationary sources and on area sources such as solvents, paints, and consumer products.
Engine manufacturers are moving forward when it comes to alternative fuel engine technology. This model year (MY96), heavy-duty engine manufacturers are offering a number of natural gas models with additional models nearing production. Electric vehicle manufacturers have several products available with new models nearing completion. Although Caterp

A simulation framework has been developed which defines a high-level architecture for a large-scale, comprehensive, scalable simulation of an Intelligent Transportation System (ITS). The simulator is designed to run on parallel computers and distributed (networked) computer systems; however, a version for a stand-alone workstation is also available

Retention issues are important to people in all aspects of business and academia. The relationship of how many people start a project and how many actually complete it is an important one, regardless of whether the project is an academic degree or a business venture. Aviation, partially due to the cost associated with training, has unique retention

The project covered by this final report, Prevention of Bridge Deck Icing Using Geothermal Heat -- Test Bridge Sections has two important aspects - the thermal performance of the test system and the structural effects of the test system. Two investigate both aspects, the project team is made up of both mechanical engineers and civil engineers. In p

This Innovations Deserving Exploratory Analysis (IDEA) project focused on developing a Scale Model Automated Highway System (AHS) Research Facility (SMARF). The SMARF is intended as an innovative scale model of an AHS vehicle system, the first step in the build out of an innovative testbed for AHS development. Once fully developed, the system would
