Main findings: Overall safety impact of a BRT / Busway
Not all systems have had a positive impact on safety
Cristiano Machado Busway, Belo Horizonte Corridor with the highest crash frequency citywide
BRTS, Delhi
Initial increase in fatalities after the implementation of the bus system

Main safety issues on BRT and Busway corridors
Pedestrians crossing in mid-block
Av. Caracas, TransMilenio
Metrobus Line 2, Mexico City
Vehicle speeds
Road width
Pedestrian infrastructure

Factors influencing crash frequencies
Counterflow
Counterflow lanes were strongly correlated with higher
crash frequencies across all our models (p<0.001)

Factors influencing crash frequencies
Location of bus lanes
Central median
Shorter pedestrian crossings
Fewer mixed traffic lanes
Some 4-way intersections turned into T junctions

Main safety issues on BRT and Busway corridors
Common crash types

The global picture of safety on BRT and Busways
Fatalities by road user type
Pedestrians 54% Car occupants
23%
Motorcyclists 10%
Bicyclists 5% Other
8%
The safest place to be on a bus corridor is inside the bus
The most dangerous: walking to the bus station

Main findings
Factors influencing crash frequencies on bus corridors
Speed
Speeding was the most common contributing factor listed in police crash reports for the Metrobus system in Mexico City

Factors influencing crash frequencies
Street width and intersection size and complexity
Metrobus Line 1, Mexico City
Road width and complexity of intersections were the most important predictors of crash frequencies.

BRT / Busways and Traffic Safety
Conclusions
The main issues to consider when designing a BRT are:
Pedestrians crossing in mid-block
Left or right turns across the bus lanes
Avoiding counterflow
Designing simple, narrow intersections
