Smart Parking Technology Reduces City Traffic Congestion

by Remy Marcotorchino, Director of Marketing, Industrial & Infrastructure
American drivers spend an average of 17 hours per year looking for parking. In large cities, this number is even higher. Drivers in Los Angeles and San Francisco spend about 85 hours annually seeking out parking, while New Yorkers spend a staggering 107 hours per year searching for spaces. Many of us are literally wasting days of our lives stuck in traffic, just looking for a place to park. 

Smart parking technology could be the key to solving this ongoing problem. Creating more parking spaces won’t necessarily solve traffic congestion in heavily populated cities. Instead, we need better management of the spaces we currently have. Smart parking technology can improve this process, both for drivers and city planners alike.

The Challenges of City Parking

Smart parking isn’t just a matter of having enough spaces for drivers who need to park, it’s about whether drivers can locate those empty spaces so that they can get off the road quickly. Studies have found that an estimated 30 percent of all drivers currently on the road are actively looking for parking. Not only does this increase the amount of time spent on the road per car, which worsens traffic, but these drivers also tend to drive more slowly than commuters who aren’t looking for parking. On average, drivers spend about 3.3 minutes looking for a space, travelling at 10mph and only covering about half a mile. This significantly slows the flow of traffic. 

Additionally, drivers searching for available parking spaces are more likely to get into a collision. About one in every five traffic accidents occurs in or around a parking lot. Often, it’s a result of distracted driving and congested lots. Drivers will pay closer attention to the side of the road or the parking lot, rather than what’s in front of them or behind them—all because they’re trying to see whether a space is available. When this happens, drivers risk getting into fender benders or injuring pedestrians. These accidents significantly delay the flow of traffic, since it takes time to move the damaged vehicle off the road. 

Smart Parking Technology Eliminates Distractions

Implementing smart parking technology in cities can reduce traffic congestion by lowering the risk of distracted driving. While different cities use this technology in different ways, many currently leverage it to make empty parking spaces more apparent to drivers. Some parking garages and heavily traveled roads now have lights or other indicators installed above parking spaces to signal to drivers whether a space is available or not. Sensors in the lights can detect whether a car is currently in the space, turning green if the space is empty and red if the space is occupied. These lighted spaces can be seen from blocks away, which reduces driver distraction. 

Rather than scanning the side of the road for empty spaces, many of which aren’t clearly marked, the driver can look straight ahead and see available, “green-lighted” parking. This also allows them to plan their parking maneuver well in advance, warning the driver behind them that they are going to pull into the space. 

Smart Parking Technology Reduces Driving Time

Smart parking technology increases parking safety, but its greatest impact on traffic congestion comes from the fact that it makes parking much faster. If city planners install sensor lights on every space, this gets drivers off the road more quickly because they can see whether a street or lot has parking available blocks in advance. In parking garages, you can even list the number of spaces available at the entrance, before drivers pull into the garage. This information receives constant updates from the sensors, ensuring that drivers always have the latest information. For instance, if a driver sees that there are no available parking spaces on a particular road and that the closest parking garage is full, rather than travelling along on the same road for blocks and blocks, they can turn onto a parallel street that does have parking available. This saves time on the driver’s commute. 

Smart parking technology can go even further than sensors and lighted spaces. Using the latest advances in the Internet of Things (IoT), we can sync these sensors to a cloud platform that feeds the information into mobile apps or online parking websites. In theory, a driver could have a GPS app on their phone providing audio directions to the next available parking space or garage. The driver can keep their eyes on the road and spend far less time driving around looking for spaces. 

Better Space Management

Another way that smart parking technology will reduce traffic volume in cities is by making it easier for drivers to pay for parking. Technology that syncs with a mobile app allows drivers to pay for parking on their phones instantly, which saves time. A parking space might become available to the next driver more quickly when the first driver can pay for parking digitally—they’re not wasting minutes looking for a ticket machine.
