One of the biggest problems Panama has is the traffic.  As the city grows and expands out in every direction, the traffic only gets worse.  The government is trying to alleviate the problem by building a new subway system.  The construction of this new subway has only aggravated an already serious problem.  Many streets are closed or partially closed creating bottlenecks and horrible traffic jams.  Patience is required, especially during rush hour. So if you are travelling from point A to point B, be sure to allow more than enough time to get there.  http://www.bus-ex.com/article/el-metro-de-panama
