  1. Lecture 6 Bus Rapid Transit, design elements and operational issues Dr. Muhammad Adnan

  2. Design Elements • Corridor Demarcation • Ridership Consideration • Bus-type selection • Alignment and cross-sectional elements • Priority Junctions • Bus Stop Location and its Design • Scheduling and Fleet Size • Fare and its collection system • BRT Terminal Location

  3. Corridor Demarcation • Result of a Macro-level Planning Model • Four stage Modelling process • Largely dependent on Potential Ridership • Future Consideration (LRT system Line-Feeder)

  4. Corridor Demarcation • Yellow Line • DawoodChowrangi (Korangi/Landhi Industrial Area) to NumaishChowrangi through locations such as Qayyumabad Junction, FTC Flyover, Shahra-e-Quaideen) -General Guidelines from Authorities Should be aligned alongside Road Median Stations utilizing built-up median space Articulated Buses (18m length) with off-board Fare collection

  5. Alignment • Features; • Identification of stretches for Separate ROW based on situational analysis or Recky survey • Identification of stretches for operation in mixed traffic based on situational analysis or Recky survey • Proposed Developments in future • Stretches of Bus Weaving (Left to Right lanes or vice versa)[AASHTOO recommendation: 250m length availability in congested conditions] • Signal Priority Junctions Identification

  6. Exclusive BRTS Lane Median Exclusive BRTS Lane Outer Exclusive Lanes Exclusive BRTS Lanes Median Exclusive Lanes (At-Grade) BRTS ELEVATED LANES Median Elevated Corridor RUNNING WAY TYPE Outer Exclusive Lanes Median Exclusive Lanes Elevated Corridor
