According to a new study led by MIT researchers, mobile phones in cars that are equipped with special software can collect useful information about the strength of bridges as they cross them. For the study, the Golden Gate Bridge was used as a case study. This technology has been added to the bridge. This is because it can keep being one of the most beautiful bridges in the world. The new app that was made for this research is still being improved. However, it could be very helpful for bridges all over the world.

How the new app works 

When a car crosses a bridge, the sensors in the phone measure the vibration of the vehicle. This data is then transmitted to a central server, where it is analyzed. We can use the data collected to identify which parts of the bridge are under stress and which parts are in good condition.

The app is still in development, but it has the potential to be very useful for bridges around the world. Bridges need to be kept in good shape. This is because big vehicles often travel one them and they can cause a lot of damage if they fall down.

This app has the potential to save lives by helping to prevent accidents caused by collapsing bridges. It could also save money by helping bridge owners identify problems before they become serious enough to require expensive repairs.

What did the study find?

The study was conducted by researchers at UC Berkeley and PCL Construction. They installed 40 sensors on one side of the Golden Gate Bridge to collect data about the structure’s vibrations. They also developed an app called “Bridge Monger” that uses the accelerometers in any smart phone to collect data about vibrations. The data collected was then compared to see if there was any difference between the two methods.

The researchers found that the data collected by both the sensors and the app were not very different. This shows that mobile devices can be used to get accurate information about how a bridge shakes. Given this, it is possible that monitoring with mobile devices could be used to add 15–30% to the life of road bridges.

The researchers behind this new app have found that it is possible to determine if a bridge’s condition could be improved with minimally invasive monitoring systems like those installed on bridges in California. To test their app, they drove over the Golden Gate Bridge 102 times and 720 meters away from its towers in driverless Uber cars with smartphones that could measure vibrations. All of the data was compared with that from 240 sensors that had been put in place over the course of three months of construction. Ten types of data were examined in detail by engineers. They wanted to know if things sounded good before installing more sensors.


This new app has the potential to revolutionize how we maintain bridges around the world. By helping us identify problems before they become serious, this app can help us avoid accidents and save lives. We are hopeful that this app will be perfected and made available to bridge owners around the world soon.
