Why is the city of Ottawa looking at burying the proposed light-rail in a tunnel?
I don't get it, beyond the usual car-centric perspective. More people-per-vehicle will have the time to enjoy the view through the city core riding the rails than driving their cars, so bury the cars instead.
Be creative! Be enlightened!
How do you get more people out of their cars, using public transport? Give them something they can't get driving, like Wi-Fi net access. Make access a privilege of daily and monthly transit pass ownership. Add Wi-Fi location services to add value within the community for both visitors and residents.
