Book Description
The objective of this research is to provide guidance to project stakeholders for the sequencing and placement of noise walls and retaining walls. The research included examining noise and retaining wall selection, standards and specifications, preferred methods and best practices for sequencing and placement, and design and construction procedures. Meetings were conducted with TxDOT district and division officials to review existing practices, identify issues, and document recommendations. Data related to noise walls were analyzed related to noise walls and the project development process. Active TxDOT projects were selected as case studies to document issues and best practices. The research documented key challenges and developed recommendations for use. Areas of recommendation include spacing, utility coordination, earlier and wide ranging involvement of stakeholders, right of way considerations, and alternative wall types and materials. Updates for TxDOT manuals are also presented. The research can be used by project stakeholders to assist in the sequencing and placement of noise walls and retaining walls and can be used to lessen the impact of noise walls and retaining walls on the overall project development process, including design, construction, and maintenance.

Book Description
This guidebook seeks to provide guidance on the sequencing and placement of noise walls and retaining walls on TxDOT projects. This includes recommendations for noise wall and retaining wall selection, preferred methods and best practices for sequencing and placement, and design and construction procedures to help reduce issues during construction and maintenance. The guidebook was developed based on information collected from stakeholder interviews, data analysis, and case studies regarding sequencing and placement of noise walls and retaining walls. It focuses on a how-to approach and includes guidelines and best practices for the sequencing and placement of noise walls and retaining walls. The guidebook includes information for a variety of users and stakeholders and can be grouped into six general areas: design, environmental, utility coordination, right of way, construction, and maintenance. These six areas have a variety of stakeholders for each.

Book Description
This design guide has been developed for the purpose of helping to achieve the following transportation systems management (TSM) goals: To maximize the person-moving capacity of roadway facilities by providing improved operating level of service for high occupancy vehicles (HOVs), both public and private; To conserve fuel and to minimize consumption of other resources needed for transportation; To improve air quality; and To increase overall accessibility while reducing vehicular congestion. Part I deals with HOV options in terms of planning and operations; Part II deals with design criteria for HOV options on freeways; and Part III deals with design criteria for HOV options on surface arterial streets.

Book Description
TRB's National Cooperative Highway Research Program (NCHRP) Report 663: Design of Roadside Barrier Systems Placed on MSE Retaining Walls explores a design procedure for roadside barrier systems mounted on the edge of a mechanically stabilized earth (MSE) wall. The procedures were developed following American Association of State Highway and Transportation Officials Load and Resistant Factor Design (LRFD) practices. Appendices A through H to NCHRP Report 663 are available online. Titles of Appendices A through H are as follows: Appendix A: Design of MSE Wall; Appendix B: State-of-Practice Survey; Appendix C: Detailed Drawing of MSE Wall for Bogie Test; Appendix D: Bogie Test MSE Wall Construction Procedure; Appendix E: Detailed Drawing of MSE Wall for TL-3 Test; Appendix F: TL-3 MSE Wall Construction Procedure; Appendix G: Crash Test Vehicle Properties and Information; Appendix H: Crash Test Sequential Photographs--

Book Description
Scoping is the process of developing a project's objectives, need, preliminary cost estimate, and preliminary schedule based on a recognized need that the project is intended to address. This study (INDOT/JTRP SPR 3944) was launched by the Indiana Department of Transportation (INDOT)/Joint Transportation Program (JTRP) to develop a synthesis of scoping processes in different State Highway Agencies (SHA). The study was conducted using a qualitative exploratory approach focusing on the review of project scoping practices across different SHAs. Focused interviews with personnel from State Highway Agencies (SHA) along with the review of documents gathered during the literature search and resources provided by SHAs were the avenues used for data collection in the study.The study focused on eleven themes for the assessment of project scoping procedures: (1) primary entity with responsibility for scoping projects, (2) timeline for scoping activities, (3) functional groups within the State Highway Agency involved in scoping, (4) cost estimation procedures, (5) application of Context Sensitive Solutions (CSS), (6) addressing maintenance needs, (7) methods of assessing scope creep, (8) tracking the quality and effectiveness of scoping processes, (9) environmental consideration in scoping processes, (10) data collection and data sharing, and (11) scoping practices which have evolved/benefited the State Highway Agency. The report presents key findings of the study and provides suggestions for further investigation by INDOT.

Book Description
The progress that has been made in developing the positive guidance concept is documented, and the meaning of positive guidance, the philosophy of driver performance upon which it is based the nature of the driving task at those locations where positive guidance is applicable, and a procedure for its application are discussed. This report describes what must be done to improve the information system at hazardous locations. Positive guidance which is an information system matched to the facility characteristics and driver attributes, is based on the premise that a driver can be given sufficient information where he needs it and in the form that he can best use to avoid hazards.
