“Occupancy” loops placed under each highway lane measure traffic speeds by gauging how much time it takes a car to travel a short distance. These loops, as traffic engineers call them, feed data to a computer in a roadside cabinet (the “ramp metering station”). Ramp meters work like that, only with sub-pavement sensors in three different locations. That’s because the lights are controlled by a computer, which is triggered by sensors under the pavement in the turning lane. You’ve probably noticed a fair number of left-turn signals on city streets that remain steadfastly red until a car or two lines up in the left-turn lane. “All the freeways you can think of, they all have ramp meters,” Jreij said. (Appropriately, the center is tucked between an onramp and an offramp.) There are more than 1,000 ramp meters just in Los Angeles and Ventura counties, the area overseen by the Caltrans District 7 transportation management center at the intersection of the 134 and 2 freeways in Eagle Rock. That’s yet another reason not to drive when it rains. ![]() Complaints about malfunctioning meters go up when it rains, Jreij said, because vandals and repair crews sometimes leave delicate electronics vulnerable to the elements. When the highway already has more cars and trucks than it can accommodate - hello, Los Angeles! - reducing the number of additional vehicles won’t magically cut commute times.Īnd finally, remember that machines break. Meters do not add or subtract from the number of cars trying to get from Points A to Points B. The second thing is what you might call the Law of Conservation of Vehicle Matter. The meters can’t allow so many cars to back up on the ramp that they interfere with traffic on the roadway behind them. The first thing you have to understand is that the metering system is designed with more than just highway congestion in mind. Metro is set to release a congestion pricing study this summer that looks at charging people to drive key freeways and roads. But it might not always be free to drive on Contact Steinberg Injury Lawyers, 24/7 at 1-80 for your free case evaluation.For Subscribers The freeway was born in L.A. If you are injured in a car accident on a Los Angeles freeway, you should seek the counsel of an experienced car accident lawyer.

Intersections in Los Angeles can be equally as dangerous as the surrounding freeways. Other high-risk freeway areas include where the 605 freeway meets the 5 freeway near Santa Fe Springs, with 174 collisions each year, and the where the 91 freeway meets Green River Road, with 155 collisions each year. Confusing signage, an abundance of semi-trucks, and multiple merging lanes are several factors contributing to the collision rate in this area. On average, 186 accidents occur on 57/60 confluence each year. This is a popular route for Valley commuters, and more than 350,000 vehicles use this section of freeway every day. ![]() At the top of the list is the two-mile stretch of highway known at the 57/60 Confluence where the 57 and 60 freeways meet. The university’s data also identified the most dangerous places in Los Angeles to drive. ![]() “After combing through the accident data for the past four years, Friday night consistently wins the unenviable prize for the most dangerous,” USC’s analysis concluded. In all, there were 23 percent more accidents on Friday evenings than on Mondays at the same time. Of the 30,756 car accidents that occurred on Fridays in 2016, nearly 5,000 of those accidents occurred during rush hour traffic. ![]() They discovered that the most dangerous time to drive on Los Angeles freeways is from 5-7 p.m. To better understand where accidents occur in Los Angeles and why, the University of Southern California’s School of Engineering partnered with the School of Communications and Journalism to determine the most dangerous times and places to drive in Los Angeles. According to the California Highway Patrol, car accidents in Los Angeles have increased by 29 percent in the last four years as compared to the 12 percent increase nationwide. The increasing rate of car accidents in Los Angeles is soaring above national averages.
