Book Synopsis Evaluation and Modification of Sight Distance Criteria Used by TxDOT by : Mark Douglas Wooldridge

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.
Book Synopsis Evaluation of Zero-length Vertical Curves by : Mark Douglas Wooldridge
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.
