What the J2735 Standard Says:

In Section 11.8 Lanes, Objects Defined in Intersections and Elsewhere of the J2735 document the following (normative) text is given:

Bicycle Lanes    Bicycle traffic is presumed to occupy and follow a bicycle lane along the described lane path (in the allowed directions of travel) and can in general be present at ANY time.  Bicycles may not come to rest at those segments which are marked as “do not block” and bicycle traffic may safely come to rest at those intermediate segments which are marked as safe islands or refuge points along the path.  In some respects, bicycle lanes share attributes of both motor vehicle and crosswalk lane types.  Bicycle lane paths cross over other lane paths and can be alongside other lane types, and merging across such lanes occurs.  In general, bicycle traffic proceeds from the edge of the described lane to the lane stop line, stopping as near to the line as conditions allow (other users can cause queuing).  In the absence of an active movement, the stop line of an ingress lane in a signalized intersection is presumed to be in the “red” state.  Outbound lanes (egress lanes), having no stop line, allow bicycle traffic to simply proceed off the edge of the map.  When an active movement allows, bicycles proceed to the end of the lane, passing the stop line, crossing to another lane as indicated by the DF_ConnectsTo data for this lane and the movement events, and proceed.

Best Practices and Usage Commentary

Add commentary on how this is to be used and correct any isuse that have come up n practice with others.

Possible Amendments

If proposed changes or additional items are known, might elect to document them here before TC can consider them, just to have a list.  Then again that may be unworkable or SAE may not want it done that way.
