"The benefits are obvious: Cleaner air and less congestion. So is one remedy. A single full commuter bus can replace 40 solo-driven cars...At current fleet levels, Ottawa's roads would be choked with about 40,000 more cars each rush hour if not for OC Transpo. Vancouver would have 60,000 more rush hour vehicles. Toronto would have an estimated 100,000; Edmonton 30,000...Yet both cities are facing car-growth trends that could soon add more cars to their roads than their peak bus fleets now displace."
