Bus Lane with Intermittent Priority Graham Carey PE., AICP BRT Project Engineer, Lane Transit District, Eugene, Oregon QUALITY TRANSIT -- NOW
Bus Lane with Intermittent Priority Concept BLIMP BLIP Dynamic Freeway Moving Bus lane Virtual Bus lane Intermittent Bus lane Adaptive Bus lane…….
Exclusive bus lane provided when bus is present BLIMP lane controlled with Bus Lane with Intermittent Priority Concept Overhead Lane-Use Control Signals In-Pavement Lights
BLIP Operations 1.All lanes open to traffic prior to bus arriving. 2.Approaching bus is detected. 3.Overhead lane-use control signals activate. 4.In-pavement lights activate. 5.Traffic begins exiting BLIP lane. 6.Bus enters cleared BLIP lane. 7.As bus clears a block, lane reopens. 8.This process continues until bus exits BLIP lane. 9.BLIP lane remains open until next bus is detected.
Features BLIMP Concept Bus detection Signal BLIMP lane BLIMP Start BLIMP End Lane-use control signals = Lane open to general purpose traffic = Lane open to bus only In-Pavement Lights
All lanes open BLIMP Concept BLIMP Start BLIMP End
Bus approaches BLIMP lane BLIMP Concept Approaching bus detected Lane-use control signals change In-pavement lights flash BLIMP Start BLIMP End
General purpose traffic exits BLIMP lane BLIMP Concept BLIMP Start BLIMP End
Bus enters cleared BLIMP lane BLIMP Concept BLIMP Start BLIMP End
Bus travels along BLIMP lane BLIMP Concept BLIMP Start BLIMP End Lane reopens to general purpose traffic after bus travels through each block
Where has it been applied University Avenue, Lisbon, Portugal Toorak Avenue, Melbourne, Australia
Key Benefits Bus travel time reduced Bus schedule reliability improved Exclusive bus lane provided only when needed! Strategy fits within existing right-of-way Existing property access maintained
Key Challenges Public information/education campaign is required Requires driver compliance Enforcement may be needed
Conclusion Successfully modeled BLIMP lane operations BLIMP lane provides benefit of exclusive lane without cost and impact Applicability where right-of-way is limited Balance can be found between transit benefits + traffic impacts Need for real-world pilot application
