6.1.1 Introduction

A collector roadway will usually serve moderate traffic volumes and provides a circulation link between local roadways and arterial highways.
Design criteria presented in this chapter apply to new construction and reconstruction projects
 for collector highways on the State Highway System.
This chapter discusses the features and design criteria for collectors and includes the following sections and subsections:
6.1 Design Considerations
  • 6.1.1 Introduction;
  • 6.1.2 Target Design Values;
  • 6.1.3 Design Speed;
  • 6.1.4 Design Traffic Volumes;
  • 6.1.5 Levels of Service;
  • 6.1.6 Travel Lane Width and Number of Lanes;
  • 6.1.7 Shoulders;
  • 6.1.8 Speed Change Lanes;
  • 6.1.9 Parking Lanes;
  • 6.1.10 Intersections;
  • 6.1.11 Medians;
  • 6.1.12 Curbs;
  • 6.1.13 Cross Slope and Superelevation;
  • 6.1.14 Grades;
  • 6.1.15 Roadside Design;
  • 6.1.16 Structures;
  • 6.1.17 Vertical Clearance;
  • 6.1.18 Grade Separations, Interchanges, and Ramps;
  • 6.1.19 Pedestrian and Bicycle Facilities; and
  • 6.1.20 Access Control.
6.2 Rural Design Elements
  • 6.2.1 General Characteristics; and
  • 6.2.2 Typical Sections.
6.3 Rural Town Design Elements
  • 6.3.1 General Characteristics; and
  • 6.3.2 Typical Sections.
6.4 Suburban, Urban, and Urban Core Design Elements
  • 6.4.1 General Characteristics; and
  • 6.4.2 Typical Sections.
This chapter is organized with an introductory section on the general design considerations for collectors, followed by separate design discussions for local roads in rural, rural town, suburban, urban, and urban core contexts.
