If you live in the Islands, you probably know already, but for the record:
Honolulu has some of the worst traffic congestion in the United States.
Not only is it bad, it's gotten worse.
The latest measure of traffic congestion comes from the
Tom Tom Traffic Index, a GPS navigational instrument company which measures traffic congestion
around the world. Tom Tom says Honolulu ranks third behind Los Angeles
and San Francisco, respectively, in the U.S.
Because of congestion, Honolulu-area drivers who have a 30-minute commute
each day waste a total of 88 hours, or nearly four full days, stuck in
traffic each year, the Star Advertiser says.
The problem is getting worse. A recent Honolulu Star Advertiser report
congestion in Honolulu increased
three percent from 2013 to 2014.
Honolulu's overall congestion level - the increase in overall travel
times when compared to a free-flow, i.e., uncongested, situation - is
32 percent. The congestion level in Los Angeles is 39 percent and 34 percent
in San Francisco. It is 58 percent in Istanbul.
Given the limited land space on Oahu and the fact that Hawaii is a great
place to live or visit, it's no surprise that our roads are crowded.
Unfortunately, this congestion leads to aggressive driving and
It's little comfort, but we should note that Tom Tom's worldwide
survey puts Honolulu at number 43 overall, and that L.A. only makes it
into the world's top 10 by taking the last spot. Istanbul, Turkey,
is the most congested city in the world, according to Tom Tom.
Honolulu's congestion level during the peak of morning rush hour is
51 percent, which is the same as in Seattle, Washington, and ranks fourth behind
San Francisco, San Jose and Los Angeles. The evening's peak congestion
level in Honolulu is 68 percent, which is the same as in San Francisco
and Houston, Texas, which ranks fourth behind Seattle, San Jose, and Los Angeles.
The best times to commute in Honolulu are
Monday evenings and
Friday mornings, while the worst are
Wednesday mornings and
Friday evenings, the Star Advertiser's analysis says.
This year, the Index reveals that evening rush hour is the most congested
time of day on virtually every road network, Tom Tom says. If you have
to drive during rush hour, you can expect to spend double the free-flow
commute time in the car, on average, stuck in traffic.
Tom Tom says its data is based on actual GPS measurements from TomTom’s
historical traffic database. For some cities they also use GPS data from
other companies, such as AutoNavi. The sample size for each city is expressed
in terms of total vehicle distance driven for the period.
The Most Clogged Highways in Hawaii
INRIX®, a provider of transportation information and driver services,

made the list. They include:
