The City of Boston implemented a proactive towing alert system using Twilio Voice to reunite cars with owners more efficiently. Prior to the implementation, police spent valuable time tracking down owners and towing companies took up space storing the cars. The city digitized their database of phone numbers, license plates, and addresses in 2011, allowing for automated voice calls to be sent to car owners. This system has reduced costs by spending less than .002% of revenue on voice alerts and has plans to expand to auto-notifications for emergency service teams and law enforcement contacting citizens directly. The system uses Twilio's API to dial car owners with vital information about the tow, including where they were towed from, why, and how to pick up their car.
