Private Installations

Introduction

1. Definition

A Private Installation or Community is a small to large restricted-access set of regularly navigable roads connected at one or more points to a public road network. The smallest example may be a single private community street protected by a gate. The largest USA installation is White Sands Missile Range at 3,200 square miles, larger than the USA’s smallest state.

Actual access restriction in these installations or communities is usually implemented by gates or guards that only allow entry by authorized individual. An unmanned means of preventing one-way access could be tire puncture strip that would deflate tires of vehicles going in one direction. In some cases access may be unrestricted by physical means, but may be implemented through patrols, cameras, or other means that would lead to a response to apprehend an unauthorized visitor.

A private installation, particularly larger government facilities, may have nested levels of access control. A particular region of the installation may be excluded to those who have general access to the larger installation. Larger examples may have all types of roads such as primary streets and highways. Smaller examples would only have roads and dirt roads.

1. Purpose

Waze should not automatically route onto or through a private installation unless the source or destination point is within the installation. Waze should be able to route on or off of a private installation at any level of nested access without entering a separate access area of a deeper level unless the destination is within that deeper installation. Waze should be able to navigate well within a larger installation that has multiple road types.

1. Approach

We suggest two separate approaches for treatment of these installations or communities, one for smaller installations and one for larger installations. Due to the large variability in these installations or communities, the editor may have to adjust or combine approaches based upon the details of the particular installation or community.

Smaller Installations

1. Definition - Smaller Installations

Smaller installations are those private installations or communities with few roads that can be easily represented by only normal street types and that have a single level of access control.

1. Preferred Approach: Smaller Installations

Examples: = Small gated/private community = Gated country club = Private school = Closed commercial campus = Airport restricted road network

Potential installations we suggest you not include: = Paid parking areas, even after a pay-station/gate

1. Treatment: Smaller Installations

Mark all roads internal to these areas as private roads.

Benefits of this approach are simplicity and a more robust solution to naïve editor error. If a new connection is made to this private road network from the public road network, no additional traffic will accidentally route through the region. In addition, manual locks are not usually required which allows other editors to more easily make changes.

Detriments of this approach are that no dirt roads, primary streets, or highways may be identified and multiple levels of access control are difficult or impossible.
