The objective of the project is to develop a framework and procedures for implementing and evaluating weather-responsive traffic management (WRTM) strategies using Traffic Estimation and Prediction System (TrEPS) methodologies. In a previous FHWA funded project, a methodology was developed and tested for incorporating weather impacts in off-line TrEPS. This capability is now included in on-line TrEPS, which interacts with multiple sources of local real-time information, to provide operators with predicted traffic states under the current and future weather conditions. The main goal is to...

Weather has a significant impact on the operations of the nation's roadway system year round. These weather events translate into changes in traffic conditions, roadway safety, travel reliability, operational effectiveness, and productivity. It is, therefore, an important responsibility of traffic managers and maintenance personnel to implement operational strategies that optimize system performance by mitigating the effects of weather on the roadways. Accurate, timely, route-specific weather information allows traffic and maintenance managers to better operate and maintain roads under...

This report assesses the potential of substitutes for gasoline to reduce emissions of carbon dioxide and other greenhouse gases (GHGs) by automobiles and light-duty trucks. The report also assesses the cost-effectiveness of replacing gasoline with varied fuels as a strategy for reducing GHG emissions, and concludes that promoting alternative fuels would be a costly strategy for reducing emissions. The study also briefly surveys other concerns that are likely to arise in making a transition from near-exclusive reliance on gasoline to widespread production and use of any alternative fuel. These...

This project identifies and evaluates transit service alternatives in the Gettysburg, Pennsylvania area, including Gettysburg National Military Park, the Borough of Gettysburg, and surrounding townships. The report concludes that public transit would allay the problems of resource damage due to traffic congestion and off-road parking, which would lead to enhanced visitor experience. Based on discussions with park service personnel and analysis of park visitation data, Volpe recommends a time frame to utilize a transit network during the peak-demand season. Finally, recommendations are made as...

This report conducts an assessment of the Marine Transportation System (MTS)functions and condition, threats to its continued operations, and vulnerabilities that make the threats more likely to materialize, within a risk and resiliency analysis framework developed for this assessment. Within this framework, the study also evaluates the inherent elements within the system which mitigate the consequences of the MTS risk factors, and identifies technology deployment and policy solutions that would enhance MTS sustainability and resiliency.

This is one of two implementation documents for the National Transportation Science and Technology Strategy. It deals with the areas of basic or enabling research which are necessary to provide the technological foundation for new and improved transportation systems. The Plan considers the roles of a broad range of parties involved in the transportation enterprise: Federal government agencies; State, local and tribal agencies; academic institutions, and the private sector. It focuses on seven areas of enabling research: human performance and behavior; advanced materials and structures;...

This report summarizes the Phase II planning effort conducted by the park and the US Department of Transportation's Volpe Center (the Volpe Center) to articulate a viable park-community pilot transit service for Morristown National Historical Park. Morristown National Historical Park consists of four separate units that played important roles during the Revolutionary War-Washington's Headquarters, Fort Nonsense, Jockey Hollow Encampment Area, and New Jersey Brigade Encampment. The combination of one-way roads, heavy traffic, and complicated intersections makes travel between the four units...

This alternative transportation plan aims to define a more efficient transit plan for visitors to Morristown. Goals include protecting environmental resources, improving visitor experiences and safety, maximizing use of infrastructure, ensuring compatibility of goals between the park and the surrounding community, and determining cost-effective means to maximize ridership. The report identifies three transportation alternatives for Morristown and analyzes their respective benefits in terms of ridership, safety, visitor enjoyment, and efficiency, as well as costs of each plan.

This document provides a checklist for environmental performance commitments in construction projects.

This study examines issues relevant to the implementation of an alternative transportation system designed to facilitate the movement of visitors throughout the park and, potentially, to sites of historical and recreational interest located outside the boundaries of the park. It provides an initial analysis of existing conditions at Minute Man NHP, and then considers various alternative transportation services (ATS) options in light of these conditions. ATS options include shuttle, tour, pedestrian and bicycle systems that can be implemented or expanded at Minute Man NHP.
