Even on the Internet, Los Angeles traffic is heavy: a quick Google search on the topic turns up nearly 140 million results. And that’s to say nothing of the dozen congested freeways crisscrossing SoCal. Fortunately, reputable Los Angeles auto-repair shops can be found all over town.

North Hollywood Auto Repair, for instance, has served LA drivers since 1937. Today, it offers oil changes and brake repairs along with more advanced services, including tune-ups for electric motor systems found in modern vehicles.

But how does the city combat its traffic problem—and thus its car-accident problem—so drivers don’t have to seek out mechanics in the first place? Here are a couple of the more promising endeavors.

Synchronized Stoplights

In addition to being a great name for an EDM artist, synchronized stoplights might eventually solve the problem of gridlock. In 2013, the city became the first major metropolis in the world to sync up all of its traffic signals—some 4,500 across nearly 500 square miles. The intricate system uses magnetic sensors planted in the road to monitor traffic flow, and a centralized computer system makes continuous adjustments to keep cars moving smoothly.

Improving the 405

After a five-year, $1 billion makeover, Interstate 405 emerged in 2014 with realigned on- and off- ramps, wider underpasses, and standardized freeway lane and shoulder widths. Though it’s too soon to tell what impact, if any, these changes will have on rush-hour traffic, early feedback does have some positives. For instance, there were 15% fewer accidents in February 2015 compared to February 2009, and rush hour now takes place from 3 p.m. to 8 p.m. as opposed to 2 p.m. to 9 p.m. The freeway can also handle 1,700 more vehicles during rush hour.
