Automobile Indicators (part two): Public Transit
Does anyone else hate getting stuck behind a bus when they 'pull over' at a bus stop, especially right before (or after) an intersection? I sure do.
Don't get me wrong, it's great that they are actually indicating, except public transit doesn't distinguish between a lateral change of position signal (turning/changing lanes) and a 'I'm-stopping-at-a-designated-bus-stop' signal. The frustration is further enhanced when the bus driver decides that this is the stop where they are going to grab a coffee or stretch their legs. Grrrr!
The same can be said when they are finally leaving their designated bus stop. While they usually indicate the upcoming movement with their indicators, it's not clear whether they are just entering the flow of traffic again, or if they actually desire to switch lanes. So, I'm proposing a simple and swift orderly change... distinguish between the two different actions.
But first, a few regulations to keep in mind, oh and we don't want to create an entire re-engineering nightmare, just a little tweak to go a long way. Federal laws dictate that turn signals are required to blink on/off, at a steady rate (between 60 and 120 blinks per minute). And automobiles are limited to red, amber and white lights - no other colours are permitted (except on emergency vehicles).
So I suggest...
- Use a circle light to indicate 'I'm-stopping-at-a-designated-bus-stop' (50 blinks per minute)
- Use a triangle/arrow to indicate the lateral change of position (100 blinks per minute)
- Use a square/rectangle to indicate braking
What do you think? How would you change it? Or, do you think there isn't anything wrong with the current set-up?
