<strong>City</strong> <strong>of</strong> <strong>Oxnard</strong> | <strong>Bicycle</strong> <strong>and</strong> <strong>Pedestrian</strong> <strong>Master</strong> <strong>Plan</strong><br />

A.4.4.<br />

Shared Roadway <strong>Bicycle</strong> Markings (SRBM)<br />

Design Summary<br />

Door Zone Width:<br />

The width <strong>of</strong> the door zone is generally assumed to be 2.5 feet<br />

from the edge <strong>of</strong> the parking lane.<br />

Recommended SRBM placement:<br />

For 7’ parking lanes a minimum <strong>of</strong> 11’ from edge <strong>of</strong> curb where<br />

on-street parking is present but may be placed more than 11 feet<br />

as conditions support. Shared lane markings adjacent to an 8’<br />

parking stall may be installed at a minimum <strong>of</strong> 12’ from centerline<br />

to curb.<br />

Minimum Design<br />

Discussion<br />

Shared Roadway <strong>Bicycle</strong> Marking stencils (also called “Sharrows”)<br />

have been introduced for use in California as an additional<br />

treatment for Class III facilities <strong>and</strong> are only currently allowed in<br />

conjunction with on-street parking.<br />

The stencil can serve a number <strong>of</strong> purposes, such as reminding<br />

bicyclists to ride further from parked cars to prevent “dooring”<br />

collisions, making motorists aware <strong>of</strong> bicycles potentially in their<br />

lane, <strong>and</strong> showing bicyclists the correct direction <strong>of</strong> travel.<br />

Placing the SRBM between vehicle tire tracks may also be<br />

considered as it will increase the life <strong>of</strong> the markings <strong>and</strong> reduce<br />

the long-term cost <strong>of</strong> maintenance to the treatment.<br />
