Instead of walking, taking public transport, or simply not traveling at all, people will instead choose to drive. This is due to a concept known as “induced demand.” When more new capacity is created, traffic is reduced in the short term, and driving suddenly becomes a more attractive option for commuters. Simply adding more capacity to roads and freeways also, somewhat paradoxically, often fails to reduce traffic congestion. This, combined with the fact that HOV lanes “suffer a 20% capacity penalty,” and that “a system with one HOV and three GP lanes carries the same number of persons per hour as a system with four GP lanes,” and it seems clear that HOV lanes largely fail at their intended purpose. Only 10% of carpools in major cities are “induced” by HOV lanes. Many cars utilizing carpool lanes are filled with passengers that would have been carpooling regardless of incentives to do so think of parents taking their children to school, or families going to the store together. While they may be popular with certain drivers, HOV lanes have largely been shown to be ineffective at their two main goals: they fail to promote carpooling to an appreciable extent and, more importantly, they can often make traffic worse than if they were general-purpose (GP) lanes. Unfortunately, few solutions work in practice as well as they do in theory. These lanes were also intended to benefit the environment by decreasing the number of cars on the road, thus saving fuel and reducing emissions. The idea behind them is simple: if people are incentivized to ride together, there will be fewer cars on the road while still transporting the same number of people. One possible solution, the high-occupancy (HOT) lane, allows city planners to more effectively utilize existing infrastructure while also pricing traffic in a politically feasible manner.īeginning in the 1970s, high-occupancy vehicle (HOV) lanes were introduced to the LA area. Of course, there is little consensus about the best way to alleviate these traffic problems, but that has not stopped city planners from trying. Estimates show that LA’s congestion costs the city $19.2 billion annually or $2,828 per driver. Traffic congestion is more than an annoyance for Angelenos. Instead, LA residents must rely on their cars for nearly all transportation. This sprawl means that unlike cities like New York or Chicago, Los Angeles is not very walkable and public transportation is often insufficient. One of the major factors contributing to LA’s traffic woes– besides its high population– is the urban sprawl the city is infamous for. Yet, it has also earned a reputation for being home to some of the most congested highways in the country. Los Angeles is known for a lot of things: Hollywood, world-famous beaches, and great food.
