Bus Priority Treatments
From Gishan Wiki
Median Bus Lane
- There will be no conflict between buses and right turning vehicles.
- Separates BRT running ways from other traffic.
- Provides a strong sense of BRT identity.
- High cost
- Accessibility to the system by the passengers is difficult
- Additional infrastructure like elevators may be required for passenger movements
- Require prohibiting left turns from the parallel roadways or providing special lanes and signal phases for these turns
- Require wide streets
Contra Flow Curb Bus Lanes
- Completely separate BRT from other traffic flow
- Two-way bus operation is possible on one-way streets
- Increases number of curb faces available for passenger stops
- Creates conflict with opposing left turns
- May disperse BRT onto several streets and reduce passenger convenience
- limits passing opportunities around stopped or disabled buses unless multiple lanes are provided
- Pedestrians have to face safety problems
Concurrent Flow Curb Bus Lanes
- Easy to setup
- Cost is lower
- Have minimum impact on intersecting driveways and street routings
- The space needed is less.
- Not very effective in reducing the travel time.
- Impact curb access requirements such as deliveries
- Added delay for buses due to conflicts between right-turning traffic and pedestrians.
- Difficult to enforce
- Dedicated lane/track can easily prevent the usage of it by other types of vehicles. No traffic jam can take place.
- Reduce congestion in roadways because of the separated track
- No obstructions with regard to parked vehicles, delivery and other vehicles
- Improved pedestrian crossing facilities for passengers.
- Easy to integrate with other modes of transportation
- Ability to climb hills with relatively high angles
- Capital expenditure is high to build up the system due to the separated track and the vehicle setup/modifications needed.
- Repairs and maintenance costs are high
- Derailment causes delays to the whole system
- Due to the tires running over the same spot in the road there is a significant rutting of the roadway
- Requires special buses for the operation which the operator has to order separately from a manufacturer.
