This report summarizes the results of a capacity project undertaken through the second Strategic Highway Research Program (SHRP 2) to advance the state of practice in this area. The objectives of this project were to (a) quantify the capacity benefits, individually and in combination,of operations, design, and technology improvements at the network level for both new and existing facilities; (b) provide information and tools to analyze operational improvements as an alternative to traditional construction; and (c) develop guidelines for sustained service rates (SSRs) to be used in planning networks for limited access highways and urban arterials (2). |
