Curb Bump-outs
Queue-jumper Lanes
A curb bump-out is an extension of the sidewalk to the edge of the vehicle travel lane. It is used at transit stops so that a bus can board and de-board passengers without having to exit and reenter traffic at every stop. This adds more efficiency and speed to stops where there are curb bump-outs.
A queue jump lane is a short stretch of bus lane combined with traffic signal priority. The idea is to enable buses to by-pass waiting queues of traffic and to cut out in front by getting an early green signal. A special bus-only signal may be required. The queue jump lane can be a right-turn only lane or installed between right-turn and straightthrough lanes. A similar arrangement can be used to permit a bus to cross traffic lanes to make a left turn immediately after serving a curb-side stop.

Bus-only Lanes Bus lanes give priority to buses and cut down on journey times where roads are congested with other traffic. A bus-only lane is not necessarily very long, as it may only be used to bypass a single congestion point such as an intersection. Some cities have built large stretches of bus lanes amounting to a separate local road system, often called a busway system.

Bus Priority Signalization A bus priority signal is a light at an intersection that indicates transit vehicles may pass though while cars often may not. This is done to move transit through traffic more quickly and/or to help buses cross several lanes of traffic immediately after passing through the intersection.
