    Only a few people in Toronto have the luck to live within walking distance from their workplace. For the rest of us, commuting(乘车上下班) is a rather unpleasant daily necessity.

So how do you avoid a traffic jam in Toronto? You can do it in the old way and listen to one of the radio stations that give regular updates about the traffic situation in Toronto's streets. Seeing the big picture of Toronto's traffic and knowing when and where heavy traffic occurs is a must. From my own experience, there are situations where a quick decision can help you make it in time for an event or a meeting. That's why we prepared three short videos showing the overall traffic situation in Toronto from dawn to night. You can click them and watch.

With the help of “Google Maps”, where you can watch the live traffic density all over the world and average traffic data based on past conditions, we were able to provide you with traffic maps for a typical(平常的) Friday.

Friday traffic in Toronto is quite fast in the early morning, with only a few hot spots showing up at the major junctions(交叉点) at 7：00 a. m. The morning traffic jam starts light at 7：30 and the traffic gradually slows down to reach a breaking point at 8：30. The roads are quite free afterwards, only Allen Road is likely to be jammed around lunchtime from 11：30 a. m. to 12：00 noon. It comes as no surprise that Friday afternoon brings heavy traffic as early as 1：00 p. m., mainly on the Don Valley Parkway. You won't have a good time getting away from the city from 4：00 p. m. to 6：30 p. m., as there is a good chance to get caught in a traffic jam. The traffic in Toronto is quite heavy on a Friday night. I hope you will have a nice Friday night in the city and a safe journey home this Friday!
