This book was released on 1998 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sight distance is an important consideration in roadway design, affecting many aspects of highway safety and operations. Ramp, interchange, and intersection designs are typically completed in tightly constrained spaces with many structural, earthwork, and roadway features present that may obstruct sight distance. These features are not easily moved; if consideration of sight distance constraints is not given early in the design process, designs may be compromised and a reduced level of safety may be encountered by the public on the completed roadway. After conducting a literature review of design criteria, three case studies of interchange ramps, and a thorough review of the TxDOT Design Division Operations and Procedures Manual, recommended revisions were prepared for the manual. These revisions include material intended to clarify and extend the consideration of sight distance in roadway design.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Evaluation of Zero-length Vertical Curves written by Mark Douglas Wooldridge and published by . This book was released on 1997 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of the research were to evaluate the use of zero-length vertical curves with respect to TxDOT design practice, construction results, vehicle dynamics, and accident history, and to compare zero-length vertical curves to minimum design vertical curves (as specified by TxDOT). Researchers determined use of zero-length vertical curves using a questionnaire distributed to TxDOT personnel in all 25 districts. Seventy-one percent of the respondents had used zero-length vertical curves. In this study, 20 zero-length vertical curves and 15 minimum-length vertical curves were evaluated. Constraints limited grade change for the vertical curves to a maximum of two percent. Evaluation included surveying the roadway profile, measuring vertical acceleration, and investigating accident information. The results showed that: sight distance is not applicable to sag curves with grade changes below two percent and is applicable to crest curves with grade changes above 0.5 percent and design speeds over 100 km/h; below 0.5 percent grade change, comfort criteria for zero-length and minimum design vertical curves did not exhibit any practical difference; between 1.0 and 0.5 percent grade change, comfort criteria showed unacceptable performance for high speed tests; zero-length vertical curves were more likely to meet drainage grade requirements than were minimum design vertical curves; and accident studies did not reveal any apparent relationship to the type of vertical curve.

Download or read book A Guide for Achieving Flexibility in Highway Design written by and published by AASHTO. This book was released on 2004 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Context-sensitive solutions (CSS) reflect the need to consider highway projects as more than just transportation facilities. Depending on how highway projects are integrated into the community, they can have far-reaching impacts beyond their traffic or transportation function. CSS is a comprehensive process that brings stakeholders together in a positive, proactive environment to develop projects that not only meet transportation needs, but also improve or enhance the community. Achieving a flexible, context-sensitive design solution requires designers to fully understand the reasons behind the processes, design values, and design procedures that are used. This AASHTO Guide shows highway designers how to think flexibly, how to recognize the many choices and options they have, and how to arrive at the best solution for the particular situation or context. It also strives to emphasize that flexible design does not necessarily entail a fundamentally new design process, but that it can be integrated into the existing transportation culture. This publication represents a major step toward institutionalizing CSS into state transportation departments and other agencies charged with transportation project development.
