Hopefully we see some quick benefits of this, because $100mill is a lot to put in a project thats supposed to increase revenues...it'll be years before they recover this amount and justify it.
This type of system is in place in a LOT of major countries, especially in Asia. Its very useful and definitely worth it when there are a lot of people in the city, but for Vancouver...I'm not so sure theres enough volume or traffic to justify doing this.
