EcoFriend
Insome places you get a ticket for speeding above the limit, others justwarn you and leave you to drive at a decent speed but the City ofCalgary is trying a new approach – scolding you like a parent. The cityhas installed new speed reading devices that are equipped with radarthat checks the speed of a passing vehicle and if its above the ratedlimit it displays a scolding message.
The city haspurchased 16 of the new devices that only flash the limit, each ofwhich is priced at $5940. The devices carry a solar panel thatgenerates all the power the system requires, which lowers theiroperating costs and means less ground wiring.
