  1. 1. Traffic Safety on Bus Corridors OverviewBackground: 2-year research projectMain findings regarding safety on bus and BRT corridorsDevelopment of design guidelinesRoad safety auditing: Rio s BRT corridors
  2. 2. Traffic Safety on Bus CorridorsCities included in the study
  3. 3. Main findings: Overall safety impact of a BRTMacrobús, Guadalajara

  5. 5. Main findings: Overall safety impact of a BRT / BuswayNot 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
  6. 6. Overview of the research MethodologyCrash data collection and analysisRoad safety audits and inspectionsDiscussions with safety experts from bus agenciesRoad test and review: getting feedback to improve the guidelines
  7. 7. Overview of the research Data analysisExample: Results from the Mexico City intersection model Vehicle collision model (NB) Pedestrian crash model (NB) Coef. Coef.Constant -1.518*** -1.857***Number of legs 0.374*** 0.252***Number of lanes per leg 0.374*** 0.341***Left turns per approach 1.705*** 1.268**Market area - 0.664***Maximum pedestrian crossing distance (m) - 0.026**Pedestrian overpass - -0.147Center-lane BRT (Metrobus Line 1) -0.029 -0.299Counterflow bus lane 0.554*** 0.389**Curbside bus lane -0.176 -0.087No. of observations 216 216Log likelihood -618.475 -518.539LR chi2 139.99 104.88Prob > chi2 0.000 0.000chibar2(01) 367.14 231.39Prob >=chibar2 0.000 0.000*** p<=0.001, ** p<=0.05, * p<=0.1, - variable not included in the model
  8. 8. Overview of the research Road safety inspections Detailed inspection of operating BRT corridors (here, Av. Caracas,TransMilenio) together with certified road safety auditors
  9. 9. Overview of the research Road safety audits Identifying safety issues in project drawings for BRT or buscorridors and suggesting improvements
  10. 10. Overview of the researchMain findings
  11. 11. Factors influencing crash frequenciesCounterflow Counterflow lanes were strongly correlated with higher crash frequencies across all our models (p<0.001)
  12. 12. Factors influencing crash frequencies Street width and intersection size and complexity Road width and complexity of intersections were the most important predictors of crash frequencies.Metrobus Line 1, Mexico City
  13. 13. Factors influencing crash frequenciesLocation of bus lanes Central median Shorter pedestrian crossings Fewer mixed traffic lanes Some 4-way intersections turned into T junctions
