The objective of this publication is to document the efforts leading up to and resulting from the Strategic Geometric Design Research Needs Workshop held in Williamsburg, Virginia, in July 2004. This workshop was a joint effort by three committees:theTransportation Research Boards (TRBs) Geometric Design Committee (AFB10) and Operational Effects of Geometrics Committee (AHB65), and the AASHTO Technical Committee on Geometric Design. This document also contains research problem statements organized in a prioritized and chronological order for possible use as a long-range geometric design research program by agencies such as AASHTO, FHWA, and other research sponsoring agencies. From a broad perspective, the responsibilities of a TRB committee are to (a) peer review research findings, (b) facilitate presentation and publication of research results in circulars and records, and (c) identify what needs to be pursued in the area of committee specific research. To further facilitate the final charge, committees are encouraged to submit research problem statements to funding agencies for consideration at the beginning of each year. In the case of geometric design, the primary funding agencies have been AASHTO, which funds research through the NCHRP, the FHWA, and individual state departments of transportation (DOTs). Both TRB committees have a subcommittee that is responsible for developing, collecting, and organizing research needs and problem statements from committee members, volunteers, other committees with similar scopes, outside peer groups (e.g., AASHTO, ITE, ASCE) and international stakeholders. Each subcommittee works to continually update and prioritize the submitted problem statements, communicate research priorities to the groups listed above, and to share the findings of research relevant to the each committee. The TRB Geometric Design and Operational Effects of Geometrics Committees and the AASHTO Technical Committee on Geometric Design met jointly in the summer of 2002 in Santa Fe, New Mexico. At that meeting, the group participated in a joint 1-day brainstorming session on research issues and priority research topics organized under the chapter headings of AASHTOs A Policy on Geometric Design of Highways and Streets (Green Book). |
