KIRKLAND, Wash., May 15, 2014 /PRNewswire/ -- INRIX®, a leading provider of traffic information and driver services, released its annual Memorial Day weekend getaway traffic forecast estimating a significant increase in Seattle traffic this Memorial Day weekend compared to last year, particularly on Friday, May 23. The upswing in congestion is consistent with data from the INRIX Traffic Scorecard Annual Report released in March, which ranked Seattle as the eighth most congested city in the U.S. Traffic increased by 7 percent last year wasting drivers on average 37 hours in gridlock.

The combination of an improving economy and a desire to do more than just a 'staycation' after one of the toughest winters of recent memory is expected to translate into more traffic over the holiday weekend. However, Seattle drivers can avoid bumper-to-bumper traffic with INRIX's help. Based on sophisticated analysis of current traffic trends, economic trends and historical traffic patterns from previous holidays, INRIX recommends the following to drivers looking to avoid the worst delays heading out of town:

  • Depart between 10-11 a.m. on Friday. INRIX's analysis predicts the ideal window to get out of town will be right after morning rush hour. This could be drivers' golden opportunity to escape the worst of the holiday traffic before the late afternoon rush ensues, which will start earlier than usual on Friday.
  • Alternatively, leave by 1 p.m. or after 6 p.m. to avoid the worst delays. Rush hour on Friday afternoon is expected to be its worst between 3-5 p.m. when the average trip will take more than 30 percent longer than normal. If drivers cannot leave right after the morning rush hour, ideally between 10-11 a.m., they should depart before 1 p.m. to avoid the worst traffic. Otherwise, traffic heading out of Seattle should be clear by 6 p.m. 
  • Download the INRIX XD™ Traffic mobile app. INRIX's app provides real-time traffic information covering arterials; city streets and other secondary roads that will help drivers avoid congestion with minimal delay.
