Just about every mode of transportation requires being a vulnerable road user such as a pedestrian who are considered the most vulnerable.
That means protecting vulnerable road users should indirectly make us safer when we bus or drive to work.
Public transit may be one of the safest modes of transportation but that’s only true when we’re inside the vehicle. When taking the bus, there tends to be a significant amount of walking which means there are driveways and intersections to cross. Some may bike part of the way then take public transit. I’ve had close call from turning vehicles when walking home from bus stops. While walking, we don’t have the protection from crumple zones. That’s why I now scan for turning vehicles.
Having safety features in a car might prevent a crash or make one safer. On our trip to work, we still have to be a vulnerable road user. It’s also possible to drive part of the way and cycle the rest of the way. The dangers include having to wait for traffic to clear before opening the door or entering the vehicle from the driver’s side, traffic in parking lots, and crossing streets if you’re parked on a different block from your destination.
This shows that not being a vulnerable road user isn’t an option for poor weather unless you’re not travelling. The advice don’t walk to your destination is possible only in theory almost all the time.
The question is how safe would the modes of transportation be if we take their weakest links into account? If we cycle on bike routes, can it actually be safer than walking to and from bus stops or train stations? Cycling is good exercise and often has similar trip times compared to taking the bus.
