An app to facilitate travel across Watford is a good idea in principle (Let’s make train users ‘appy, February 6).

But in practice, as with all apps, it could end up marginalising many people. Not everyone has access to the internet - and far fewer have a state of the art smartphone.

Hopefully it will promote public transport rather than be a glorified car sat nav.

Far more apt than an app would be a website like nextbuses.mobi that is not device or platform-specific, so it can be accessed by all web-capable devices.

Added to this could be a roll out of more Intalink green travel boxes such as the one outside the High Street station that allows users to enter their journey details and the box returns viable routes.

Better still would be large clear signs at bus stops indicating the bus number it serves and times.

Only last week Friends of the Earth transport campaign think tank suggested that making bus travel free to all users - not just seniors - would encourage more to travel by public transport. In the very least it’s time the Oyster card scheme was extended to Watford buses.

The council could do far more to improve the infrastructure to encourage use of public transport and deter use of the car: extend bus lanes so some roads such as Clarendon Road are solely for bus use; park and ride schemes.

So an app is great so long as other measures to encourage people are in place.
