| 摘要： | The year 2000 edition of the Highway Capacity Manual (HCM), commonly known as the HCM2000, represented a major step forward in highway capacity analysis capabilities. However, there are still improvements to be made in the HCM, and its present scope does not fully address all facility types of potential interest to HCM users. This document sets forth a research program for improvement of the HCM. It is the product of extensive deliberations by the members of the TRB Highway Capacity and Quality of Service Committee (HCQS) and of feedback from users of the HCM. The program recommends the conduct of 38 research studies as a means to permit improvements to the present HCM and upgrade future editions to meet user needs. The estimated total cost of the program is $16.0 million over the next 10 years. This estimated cost includes direct research expenses, the development of draft chapters, and the production of a major revision of the HCM. |
