A dynamic, flexible advertising estate can add a far greater contribution to a transport operator's bottom line. Main city commuter rail stations benefit from an audience profile that changes throughout the day, and as such an increasing number of advertisers are looking to media solutions, such as digital, which enable them to engage with their specific target market. With emerging markets looking at 'railway cities' to accommodate the needs of an increasing upwardly mobile audience and building spacious new railway terminals that resemble international airports, it is vital that the media footprint fits the design brief, is desirable to potential clients and is future proof. PSI Consulting assists operators by giving an independent evaluation of the potential value of their media estate and advice on implementing the advertising footprint that best suits their needs.
