I might have one for you...<br>road crossings are always calibrated for the slowest, meaning traffic has to wait even when theres no disabled or elderly people.<br>why not have a quick button and a slow button, so those who need extra time to cross can have it but generally a lot of time is saved.<br>I can't believe this hasn't been thought of, especially with the amount of traffic on the roads, the damage to the environment this causes and the rise in fuel costs but maybe you can investigate and spread the word.
