Route Research produce audience estimates for out-of-home advertising in Britain that tells subscribers how many people see an advertising campaign, and how often they do so. The information is used for planning, trading and valuing advertising investment in the medium. Mediatel developed the industry approved API for Route, a simple interface to software that performs the complex Route audience calculations. 

With this API clients can easily build Route data into their own systems. New release data is automatically loaded and validated against check figures, as well as any re-releases or corrections issued. Route clients are able to focus on the added value activities of defining their own user interface and incorporating their own planning and optimisation strategies.
