Accommodating cyclists signalised intersections
Read More At areas with high volumes of right turning vehicles, or low levels of motorist yielding compliance, an active display sign may be used to further alert drivers to the potential of conflict movements with bicyclists.
This sign should use signal detection and actuation to activate only in the presence of bicyclists.
Traffic control improvements directly applicable to pedestrians include: Each of these treatments is discussed in the following sections; median crossing islands were addressed in Chapter 8.
This may result in shorter cycle lengths and less delay for all users.
The City of Austin.“It appears that [ingress lanes] provide cyclists with a considerable advantage in legally accessing [the bike box].” The site with no feeder lane “clearly showed that many cyclists were unable to reach the reservoir.” An egress lane should be used to clearly define the potential area of conflict between motorists and bicyclists in the intersection when intersection is operating on a green signal indication.

Crash severity increases significantly between 20 and 40 mph.(105) However, vehicles turning right will be forced to decelerate more rapidly in attempting the right turn.
This could lead to rear-end conflicts with through vehicles, particularly if a separate right-turn lane is not provided and the through movements have high speeds.
