Greetings! I would like to answer the following question sent to me and thank the transit professional for doing so:
"Just this week, we have had three bus accidents. One type of ‘repeater accident’ has been occurring in the garage involving the driver’s left rear side of our 45-foot [bus]. When turning right, the left rear driver’s side swings out and catches the roof support pole. The last two accidents took out the rear side glass. I need some preventive ideas.”
This is the classic overhang problem. These types of incidents have decreased dramatically over the years as a result of the well-lit, state-of-the-art depots being built and the additional training given to the shifters/drillers — individuals who, at the end of the day, take returning buses and place them in their overnight slots.
During the days of poorly lit, outdated, smaller depots, or ‘barns’ as they were once called, this type of contact within the obstruction-filled space occurred during the “Still of the Night.” Often, the damage was not noticed until a responsible operator on pull-out conducted a thorough pre-trip inspection the following morning. Some of you may remember the days prior to pre-trip inspections, when a ‘no knowledge’ response was usually the term that was used when being questioned about bus damage, in general.
Regarding the question, knowing your bus model dynamics (e.g., pivot points and mirror positioning) is just part of the solution. Some of the causes of these contacts occurring within the depots are:
1) Failure to check for insufficient clearance around the bus.
2) Failing to re-adjust mirrors upon relieving the departing operator.
3) Failing to stay alert and forward-plan around the trouble spot.
4) Oversteering to the right.
5) Speed, although I would hate to think that speed (especially in the depot) would be a contributor.
Consider the following:
1) Ensure that the pole is clearly visible, even if it means painting it a different color that would make it even more visible to alert the operator of this particular trouble spot.
2) Create a handout to be posted in the depots and around the garage pull-out area alerting all to this problem.
3) Bring all student operators around this turn and provide them with the opportunity to watch you negotiate around this area. Then, have them do it while alerting them to the importance of knowing your surroundings and the limitations of your bus.
4) Go to your outdoor training area and place a cone near the pivot point of each different size bus and show them the consequences of what happens when oversteering and not thoroughly understanding the different pivot points (not getting permission), by moving the cone from the pivot areas to a point that will create contact with the bus. You can also go to the simulator and create a scenario where, unlike in the depot, the low-risk environment of a simulator can effectively deal with a high-risk situation of contact with fixed objects.
An operator handout reminder for the garage/depot area can consist of the following points:
- How much clearance do I have?
- What model bus am I operating?
- Are my mirrors providing the info I need?
- What must I do differently?
- When in doubt, secure bus and GET OUT AND LOOK!
