INRIX's tip to drivers? Know before you go.
The afternoon rush hours on Thursdays and Fridays are generally the most congested. If you're flexible, keep the following best and worst commuting days and times in mind before pulling out of your driveway:
Worst traffic day: Thursday
Best weekday for traffic: Monday
Worst weekday morning: Tuesday
Best weekday morning: Friday
Worst commuting hour: Friday, 5 to 6 p.m.
Best commuting hour: Friday, 6 to 7 a.m.
Worst evening commute: Friday
Best evening commute: Monday
Still, even if you can't plan ahead, a number of resources from MapQuest to iPhone and Android phone traffic apps can help you. With real-time information on congested roads in your area, you'll likely spend less time sitting bumper to bumper and more time doing what you set out in your car to do in the first place.
