The guide also has a glossary to acquaint the reader with certain expressions and terminology that are used in this guide. The five chapters in the guide are described below.
Planning for Freeway and Arterial HOV Facilities
For an HOV facility to be successful, a number of early assessments and commitments must be made. Chapter 1 identifies those initial considerations that are critical to assuring an efficient and effective HOV operation.
Chapter 1 also describes HOV lane planning issues. The planning section includes an overview of the process, planning for facilities on freeways and arterials, public involvement, and planning for implementation and evaluation.
Operating and Enforcing HOV Facilities on Freeways
Chapter 2 of the guide describes operational and enforcement considerations for implementation of a successful freeway HOV facility. The operational issues that are described include consideration of the design during decision-making regarding operations and enforcement, selection of eligible vehicles, hours of operation, incident management, and pricing issues.
Design of HOV Facilities on Freeways
Chapter 3 includes the various types of HOV facilities that may be used in conjunction with freeway sections. These facilities include HOV facilities in separate rights-of-way, barrier-separated facilities (reversible or two-way), concurrent flow lanes, and contraflow lanes. HOV queue bypass lanes for HOVs are discussed, as well as online transit stations. A separate section on signing and pavement markings is provided. Design considerations such as example cross sections and schematics are provided for each facility type. A general section at the beginning of Chapter 3 describes various design features applicable to many HOV facility types.
Operating and Enforcing HOV Facilities on Arterial Streets
Chapter 4 provides information related to the operation and enforcement of HOV facilities on arterial streets. This chapter describes topics such as conceptual alternatives for arterial HOV facilities, vehicle eligibility, operating hours, enforcement, and intersection control, driveway access, and curb-use considerations.
Design of HOV Facilities on Arterial Streets
The material presented in Chapter 5 is intended to serve as a guide for the design of HOV facilities on arterial streets. This guidance includes geometric design and also traffic-control aspects for arterial HOV facilities.
