9.1 Introduction

circulation system

The image of the installation is greatly determined by the design and location of roadways, walkways, entrances, and parking lots.  The primary roadway system and parking lots utilize considerable amounts of land and are a visually dominant element of any installation.  The design criteria for the location of primary circulation elements is presented in Section 7, Site Planning.  This section discusses the details of circulation designs and their impacts.

The circulation system provides a primary vantage point from which all installations are viewed.  Safe and efficient vehicular, pedestrian, and bicycle traffic movement results in better orientation and contributes to the development of a positive environment for installation personnel and visitors.  The circulation component is used to assess the circulation elements of the installation and identify specific characteristics.

Roadways, pedestrian walkways, and bicycle trails will be designed to provide a hierarchy of circulation design and carrying capacity.  Functionally, a hierarchical network can be created that separates incompatible types of traffic.

Visually, the circulation hierarchy can be reinforced through design, planting, signage, and lighting to promote a more attractive visual experience and promote a sense of orientation.
