In late 2013, Vancouver, BC topped the list of most congested cities in North America by the annual TomTom Travel Index. On average, peak hour travel time was 36% longer than during non-rush hours. For a Vancouver commuter with a 30-minute drive, the cumulative delay amounted to an additional 93 hours (more than 11 working days) behind the wheel each year. TomTom, a leader in consumer GPS units, obtained this data from its millions of GPS units and tracked traffic flow to compile its yearly report. Vancouver’s significant strain on transportation stemmed from the population and economic growth in the region.
