5 foot "traffic meter" before the junction displays traffic situation
Driver stress and additional traffic congestion is exacerbated because drivers often cannot tell how bad traffic is until they have already committed to a driving route.
For example, there are two routes to work - the tunnel is faster on 80% of the days, but on the other 20% it's gridlocked. By
the time you drive up the on-ramp and see the jam you're scr*wed.
I have seen traffic webcams - but who can access the internet while driving? Alternatively, a big projection TV screen could show the condition of traffic at the key intersection - but light levels are a problem and the equipment is too pricey.
Instead, a 5 foot tall "traffic meter" (like a sound level indicator) before the junction could display the traffic situation.
Honest traffic sign
[krelnik, Oct 04 2004]
||Baked in many large cities, including the one I live in. They have huge scoreboard-like signs over the road every so often that tell you about any traffic problems ahead. The text on the signs is put up by folks who monitor those traffic cameras.
||The George Washington Bridge in NYC has a sign that tells you whether to take the upper or lower bridge, based on traffic flow...
||See link for an example of one with refreshing honesty.
