Guidance for Cost Estimation and Management for Highway Projects During Planning, Programming, and Preconstruction


Book Description

'TRB's National Cooperative Highway Research Program (NCHRP) Report 574: Guidance for Cost Estimation and Management for Highway Projects During Planning, Programming, and Preconstruction explores approaches to cost estimation and management designed to overcome the root causes of cost escalation and to support the development of consistent and accurate project estimates through all phases of the development process, from long-range planning, through priority programming, and through project design. NCHRP Web-Only Document 98 details the steps followed by the research team in the development of NCHRP Report 574"--Publisher's description.

Rail to Truck Modal Shift


Book Description

The continued loss of rail network infrastructure and rail service throughout the US has most instances resulted in the modal shift of rail freight back to truck. Rail freight converted to truck may have significant impact on pavement maintenance costs and activities due to the increased highway traffic volumes. This study will investigate three short-line rail routes in Minnesota, Wisconsin and the Upper Peninsula of Michigan and will determine the potential impacts of diverting rail freight flows to truck. A logistics flow routing will be created illustrating the new truck flows by highway classification and usage. The targeted highways current conditions and asset management techniques will be documented. A pavement maintenance model will be used to determine the incremental pavement maintenance cost per ton-mile if additional freight moved over various classes of highway and their impact on highway funding.




Gravel Roads


Book Description

The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.










Assessing Highway Tolling and Pricing Options and Impacts


Book Description

"TRB's National Cooperative Highway Research Program (NCHRP) Report 722: Assessing Highway Tolling and Pricing Options and Impacts provides state departments of transportation (DOTs) and other transportation agencies with a decision-making framework and analytical tools that describe likely impacts on revenue generation and system performance resulting from instituting or modifying user-based fees or tolling on segments of their highway system. Volume 2: Travel Demand Forecasting Tools provides an in-depth examination of the various analytical tools for direct or adapted use that are available to help develop the forecasts of potential revenue, transportation demand, and congestion and system performance based on tolling or pricing changes. Volume 1: Decision-Making Framework includes information on a decision-making framework that may be applied to a variety of scenarios in order to understand the potential impacts of tolling and pricing on the performance of the transportation system, and on the potential to generate revenue to pay for system improvements"--Publication information.




Traffic Control Systems Handbook


Book Description

This handbook, which was developed in recognition of the need for the compilation and dissemination of information on advanced traffic control systems, presents the basic principles for the planning, design, and implementation of such systems for urban streets and freeways. The presentation concept and organization of this handbook is developed from the viewpoint of systems engineering. Traffic control studies are described, and traffic control and surveillance concepts are reviewed. Hardware components are outlined, and computer concepts, and communication concepts are stated. Local and central controllers are described, as well as display, television and driver information systems. Available systems technology and candidate system definition, evaluation and implementation are also covered. The management of traffic control systems is discussed.
