Samsara supports the ability to integrate with myriad third party routing software like VersaTrans, Transfinder, RoadNet, and many others.
Samsara can import routes from these programs, analyze planned vs. actual route runs, report on driver performance, and even export GPS data into these programs by leveraging the Samsara API.
Contact your Samsara sales team for more details on how your organization can integrate your routing software with Samsara.
