Cambridge Mobile Telematics (CMT) has announced its most recent findings on distracted driving. The data collected from more than 65 million trips over the last six months revealed distracted driving occurred during 36.1 percent of trips nationwide, up 5 percent from last year.

CMT’s smartphone app collects data and provides actionable insights for drivers to improve their on-the-road performance by measuring five driving behaviors: phone use while driving, at-risk speeding, hard braking, harsh acceleration and cornering. The most recent data collected showed several patterns of distracted behavior, including:

• The evening commute has the greatest amount of distraction, with 38 percent of trips exhibiting distracted-driving behavior between 4 p.m. and 6 p.m.
• Most distractions occur at speeds of 30 to 40 mph.
• Drivers spend more time distracted on local roads (57 percent of the time) versus on highways (43 percent of time).
• The average length of distraction time per trip was 2.67 seconds per mile.

This year, CMT also compared distracted-driving behaviors across the United States, analyzing eight specific cities: Boston, Chicago, New York, Los Angeles, Washington D.C., Houston, Philadelphia and San Francisco. All exhibited more than the national average of time spent distracted while driving, with an average of 11 percent more time distracted per trip (the national average is 36.1 percent). The study also found:

• Houston and Philadelphia had the highest percentage of trips with distraction, with 39.99 percent and 39.97 percent, respectively.
• Philadelphia (3.77 seconds), Boston (3.4 seconds) and Washington D.C. (3.39 seconds) had the longest average length of distraction time per mile.
• New York, Los Angeles and San Francisco were the only cities that came in under the national average of trips with distraction, with 32.9 percent of trips, 33 percent and 33.4 percent, respectively.
