"Green Man Plus" gives seniors more time to cross...

Pedestrian crossing signals have a tricky balance to strike in giving people enough time to cross, but not so much time that it unnecessarily slows traffic. The problem becomes more difficult when considering the difference in walking speed between able-bodied people and the elderly or otherwise impaired: what's good for the former is insufficient for the latter. Singapore has an excellent solution called "Green Man Plus," where anyone who needs to can tap an RFID card by the signal button to get a longer crossing time. This is a great approach - at least until crossing cameras are smart enough to detect pedestrian paces and adjust accordingly.
