Median Bus Lane

Advantages

  1. There will be no conflict between buses and right turning vehicles.
  2. Separates BRT running ways from other traffic.
  3. Provides a strong sense of BRT identity.

Disadvantages

  1. High cost
  2. Accessibility to the system by the passengers is difficult
  3. Additional infrastructure like elevators may be required for passenger movements
  4. Require prohibiting left turns from the parallel roadways or providing special lanes and signal phases for these turns
  5. Require wide streets

Contra Flow Curb Bus Lanes

Advantages

  1. Completely separate BRT from other traffic flow
  2. Two-way bus operation is possible on one-way streets
  3. Increases number of curb faces available for passenger stops

Disadvantages

  1. Creates conflict with opposing left turns
  2. May disperse BRT onto several streets and reduce passenger convenience
  3. limits passing opportunities around stopped or disabled buses unless multiple lanes are provided
  4. Pedestrians have to face safety problems

Concurrent Flow Curb Bus Lanes

Advantages

  1. Easy to setup
  2. Cost is lower
  3. Have minimum impact on intersecting driveways and street routings
  4. The space needed is less.

Disadvantages

  1. Not very effective in reducing the travel time.
  2. Impact curb access requirements such as deliveries
  3. Added delay for buses due to conflicts between right-turning traffic and pedestrians.
  4. Difficult to enforce

Guided Busway

Advantages

  1. Dedicated lane/track can easily prevent the usage of it by other types of vehicles. No traffic jam can take place.
  2. Reduce congestion in roadways because of the separated track
  3. No obstructions with regard to parked vehicles, delivery and other vehicles
  4. Improved pedestrian crossing facilities for passengers.
  5. Easy to integrate with other modes of transportation
  6. Ability to climb hills with relatively high angles

Disadvantages

  1. Capital expenditure is high to build up the system due to the separated track and the vehicle setup/modifications needed.
  2. Repairs and maintenance costs are high
  3. Derailment causes delays to the whole system
  4. Due to the tires running over the same spot in the road there is a significant rutting of the roadway
  5. Requires special buses for the operation which the operator has to order separately from a manufacturer.
