| 摘要： | In a recent project for the Kentucky Transportation Cabinet (KYTC), researchers were tasked with developing a method to objectively evaluate the access for large trucks between intermodal or other truck traffic generating sites the National Highway System (NHS). The routes evaluated were the actual roadway segments used by large volumes of trucks traveling between the intermodal or other facilities and the NHS. This choice to evaluate specific heavily used roadway segments, as opposed to evaluating an entire highway or roadway corridor was based on the recommendation of the state-wide Intermodal Advisory Panel which advised the Cabinet on intermodal issues. This allowed researchers to identify and focus on the actual problems being experienced by the truck traffic, even when the routes included segments of many different highways and jurisdictions. Part of this study included the development of objective measures that could be used for comparing and prioritizing problem sections. This paper documents the methodology that was developed and is currently being used to evaluate routes to SO truck trip generators throughout Kentucky. The procedure begins with a telephone survey with site operators/managers to identify problems along the route. Each route is evaluated with respect to three types of features: subjective, point and continuous. The rankings of each point and continuous element into the categories of “ preferred ” , “ adequate ” , and “ less than adequate ” is converted to a relative urgency rating by assigning relative weights for truck volume mid section length Point and subjective features are identified for spot improvements where appropriate. Finally, the research team grades the overall route on a subjective scale of 1 to 10. |
