I ’d like to accuse…

It was the rookie bus driver, Colonel Mustard, and he was rear‐ended on rainy day by a out

  • f state tourist while driving a

bus with lots of advertising on the back, and he forgot to turn

  • n his 4‐way flashers.

Rear‐ended Collisions Revenue Miles

This means revenue miles account for about 43% of the variation in rear‐ended

  • collisions. The

remaining 57% is due to other factors.

Observations from the Site Visits

  • Collision investigation process is very similar

across agencies.

  • Variation in preventability assessment

– HART: Mgr. of Safety and Security – Sarasota: 4‐person committee (2 from mgt. and 2 from union) – LeeTran: Deputy Director and Senior Ops Supervisor

20

Observations from the Site Visits

  • Most rear‐ended collisions occurred when

the bus was already stopped.

  • “I didn’t see the bus,” most common

excuse heard by supervisors.

  • Video footage standard part of investigation

– Not all agencies have telemetry with videos – No agency has rear facing cameras that could capture moment of impact

21

Observations from the Site Visits

  • All agencies report monitoring collision trends

to inform training and adjusting stops.

  • Communication is key

– PSTA places samples of broken equipment in the drivers’ room with the price tag – RTS and SCAT has periodic “all hands” meeting with the director – RTS has FYI form drivers can use to inform mgt. about any unsafe conditions

22

Observations from the Site Visits

  • LeeTran reported many rear‐ended

collisions occur in less urban parts of service area where speed limits are higher.

– Worth investigating further.

  • Need to address distracted driving

– CUTR has received feedback from agencies in support of statewide campaign

Statew ide Cam paign? We already have… Why not a similar campaign for buses?

24

Next Steps

  • Complete last 4 site visits by Oct. 16

(tentative)

– LYNX – Indian River – St. Johns – SCAT (Brevard)

  • Draft Final Report by Dec. 25, 2015
  • Final Report by March 25, 2016
