Abstract:The purpose of this handbook is to provide guidance in determining whether or not speed
harmonization and peak period shoulder is feasible for a given site or set of sites. The content of
this handbook is based on the analysis conducted for this project. Additional information
regarding the topics presented in this handbook can be found in project report 0-5913-1, Speed
Harmonization and Peak-Period Shoulder Use to Manage Urban Freeway Congestion.
The guidance for conducting feasibility analyses, presented below, primarily integrates the cost
benefit analysis framework and the operational and deployment strategy presented in Chapter 8
of the project report. The collective goal is to intelligently apply speed harmonization and peak
period shoulder use as a combined traffic control strategy that delays the onset of severe
congestion and increases throughput. Guidance for assessing the feasibility of speed
harmonization and peak period shoulder use is organized into six analysis components. These
are:
1) Identify candidate sites;
2) Construct and run microscopic and mesoscopic simulation;
3) Identify infrastructure improvements;
4) Develop an enforcement strategy and public education plan;
5) Apply cost benefit analysis framework; and
6) Consider potential qualitative impacts.
