Bus Priority - Other Measures

Bus Advance Signals

Bus advance signal

Bus advance signals enable buses to beat the traffic at traffic lights. An extra set of traffic lights, with a special white "B" bus signal allows buses to drive through the intersection before other traffic.

Systems like this operate in:

• Kent Terrace
• Chaytor Street
• Courtenay Place
• Riddiford Street
• Lambton quay
• Victoria Street.

Bus Boarders

Bus boarder

A bus boarder or "in-lane bus stop" is the reverse of a bus bay. It intrudes onto a traffic lane to make it easier for buses to stop and get back into the traffic flow. Other traffic may have to wait briefly while passengers board.

Transit Lanes

Transit lanes can be used by vehicles that carry a set number of passengers. The lanes are usually classed as T2 or T3, meaning that two or three people respectively need to share the vehicle to be able to use the lane.

Bus Bypass or Pocket

Bypasses are special lanes at intersections that allow buses to travel around stopped traffic. At some intersections buses are allowed to travel straight through from a left-turn only lane, helping them to bypass the queues in other lanes.

Clearways

Clearway

More clearways, which could be restricted to buses only at certain times and all traffic at other times, are likely to be introduced. Like bus lanes, stopping and parking is prohibited in clearways at peak times.

Signal Pre-emption

Signal pre-emption detects when a bus is coming and turns or keeps traffic lights green to let the bus through an intersection. The system consists of detectors in the road which are linked to traffic lights.

When a bus passes over a detector, a message is sent ahead that a bus is on its way. If the lights are about to turn red, they are instructed to stay green until the bus passes through. If the lights are red, then the green phase is brought forward.

Real-time Information

Signal pre-emption detectors can be linked to electronic signs at bus stops which tell passengers exactly when to expect the next bus. Variable information signs displaying scheduled departure times will be introduced at on-street bus stops in the central city.
