Should an ambulance or fire truck come upon heavy traffic, it may not physically be able to find a route through. Additionally, a roadway with heavy congestion makes it difficult for emergency vehicles to get to their destination. A less efficient vehicle creates higher costs of gas for drivers and adds to pollution in the air. As traffic stops and starts, cars burn fuel at a less efficient rate. Negative aspects of congestion on roadways, however, include more than drivers’ stress levels. Using defensive driving techniques can help keep you safe in congested traffic. This angry reaction to traffic can be dangerous as drivers make rash decisions that may lead to an accident. Stressed drivers are more likely to engage in road rage. These delays contribute to stress when people are late to their jobs as well as wasted time. Daily commutes with heavy traffic create delays as drivers make their way to work. Some drivers might find it more difficult to estimate the time needed to get to a destination. Drivers who deal with traffic may face emotional effects. In addition to being annoying or frustrating, heavy traffic can cause a ripple of negative effects. The shifting speeds created a shockwave of braking and accelerating throughout the circle. Each car slowed and sped to meet the speed of the car in front of it and attempt to maintain the same speed. These small adjustments created a ripple effect around the circle. After some time, drivers began to speed up or slow down on accident. Using a single track, the researchers instructed drivers to maintain the same speed and distance between one another. Traffic finally disappears when the wave reaches an area with the correct number of cars for the roadway.Ī Japanese study created a phantom jam and the resulting traffic wave. ![]() When cars begin to accelerate in waves, the most congested part of the roadway moves backwards down the line. Known as a traffic wave, as cars slow down, the roadway gets more congested. Roadways that are facing too many vehicles for the amount of space can take a long time to clear. Congestion is caused as these bursts of slowdowns allow time for more cars to enter the roadway. This carries on to each of the cars behind and causes a slight slowdown. For example, a driver who cuts into the adjoining lane suddenly makes the drivers behind them slam their brakes. This flow then ripples through the other cars in the area. Each time drivers slow down or speed up affects the flow of traffic around them. The jam, not caused by an obvious factor such as an accident, is sometimes known as a phantom traffic jam. The section of road before the construction zone soon has more cars than it can handle at normal speeds.Įven the smallest of adjustments by one driver can cause a massive traffic jam. Even though drivers are usually aware of the construction, the sudden slowing of vehicles causes a backlog. Vehicles head toward the road construction at the normal speed limit, then slow to meet the construction. The entire time a road is closed due to an accident, more cars are entering the roadway and joining the already slow traffic.Ĭonstruction zones are known for having slower speeds and lane closures. Even a large highway can have several lanes of traffic completely closed for a car accident. ![]() Drivers must stop for the accident and allow emergency vehicles to maneuver. While it is true that accidents and construction create a lot of congestion when they happen, much of the day-to-day traffic jams on a commute, however, are caused by drivers’ decisions.Ī car accident on a roadway can quickly bring movement to a halt. Road construction also takes a lot of blame for causing traffic. Most people assume traffic happens from car accidents or a stalled vehicle. Several factors can cause a road to have too many cars and thus create a traffic jam. This guide will help you understand how traffic starts and why it happens. If the road doesn’t have space for all of the vehicles, people have to drive slower and closer together to fit more cars. ![]() Traffic happens from a roadway having too many cars on it at once. Los Angeles, with over 100 hours a year spent in traffic, was ranked highest in the world for traffic congestion.Īlthough almost every driver has dealt with traffic, few realize why it happens. ![]() In a study by INRIX, three major California cities ranked in the top fifteen of US cities for most traffic congestion. Many face heavy traffic each day on their commute to and from their jobs. Even drivers who live outside of major metropolitan areas have likely experienced a heavy traffic jam from road construction or an accident. Traffic is a well-known annoyance for California drivers. ![]()
