This report provides an overview of the freight movement system within the Baltimore region, with an emphasis on intermodal facilities, identifies key long-range issues, and proposes investments and actions for inclusion in the 1997 Baltimore Regional Transportation Plan.
As part of the planning process that culminated in the development of the 1994 Transportation Policy Plan for Washington State, the subcommittee responsible for creating the Pedestrian Policy Plan recommended that the Washington State Department of Transportation (WSDOT) coordinate with other state and local jurisdictions to develop a pedestrian de

The Washington State Department of Transportation (WSDOT) prepares the annual transit statistical summary. The intent for this summary, required by Section 35.58.2796 RCW, is to provide uniform data to transit providers, the Legislative Transportation Committee, and local and regional governments. The summary contains narratives describing each tra

This report documents the results of a Federal Highway ADministration (FHWA) study of the agency's Highqay Performance Monitoring System (HPMS). The purpose of this study was to assist FHWA in conducting a comprehensive review of the HPMS, designed to result in recommendations as to the future form and direction that this major FHWA data system sho

This report is the fifth edition of Urban Transportation Planning in the United States and updates the evolution of planning and policy to mid-1997. The report focuses on key events in the evolution of urban transportation planning including developments in technical procedures, philosophy, processes and institutions. But, planners must also be awa

An investigation into the behavior of cross frame diaphragms in steel highway bridges was conducted. The investigation involved both field testing of three bridges as well as analytical studies using finite element analysis. Diaphragms were removed from the structure and less than half replaced by a new diaphragm design. The remaining diaphragms we

Four alternative (to loop detection) sensor types were tested in freeway construction areas in Houston. The Whelen Doppler radar units, once attuned to the local conditions, appear to render acceptable speed measures. The side fire microwave ranging sensor (R TMS from EIS) appears to be very suspectable to creating multiple reflections when exposed
...
This research developed, tested, evaluated, and recommended improved methods for communicating with drivers at both active and passive highway-railroad grade crossings to accomplish the study objectives. A driver comprehension survey of highway-railroad grade crossing traffic control devices, an in-vehicle observation of driver behavior at highway-

This report summarizes data collection activities performed at eight different sites in Texas urban areas. The datawere collected to help develop and test bicycle and pedestrian travel demand forecasting techniques. Theresearch team collected data about actual bicycle and pedestrian facility usage rates (i.e., 12-hour volume counts)and trip charact
...
The major objective of this study is to develop empirical methodologies for modeling ramp driver acceleration-deceleration and gap acceptance behavior during freeway merge maneuvers. A large quantity of freeway merge data were collected from several entrance ramps including both parallel and taper type acceleration lanes capturing a wide traffic fl

This project is an analysis of Oregon's Corridor Safety Improvement Programs implemented on Oregon Route 22 and Oregon Route 34. Improvements weremade along each corridor in 1993.The project used a mail-out survey to determine the level of awareness and perception of safety among drivers due to the improvements made along eachsafety corridor. The r

This study evaluates the performance of lime/fly ash stabilized base as an alternative to soil cement stabilized base for flexible pavement systems on reconstructed highways in Louisiana. Louisiana has historically used soil cement for most flexible base construction due to its low cost, high compressive strength, and ease of construction. However,

The report presents a procedure for predicting creep strains of geosynthetics using creep tests at elevated temperatures. Creep testing equipment was constructed and tests were performed on two types of geosynthetics: High Density Polyethylene (HDPE) geogrid, and Polyester (PET) geogrid) typically used in soil reinforcement applications.The procedu

Novachip was a French process utilizing a unique paving machine manufactured in Germany. This machine simultaneously applied an evenly distributed asphaltic emulsion and a thin lift of hot mix to the existing roadway surface.The project extended five and a quarter miles on Louisiana Highway 308 parallel to Bayou LaFourche. The project began Septemb

The purpose of this project was to design and construct lime/fly ash stabilized base course test sections which would be economical compared to a soil cement stabilized base, utilize a recyclable material, and possibly reduce shrinkage cracking on bases and the subsequent reflective cracking of the riding surface. Satisfactory results from this pro
