First Bus has launched a new campaign to highlight that one double-decker can take up to 75 cars off the road.

"Project 75" was unveiled by the travel giant who parked a double-decker electric bus at Silverburn Shopping Centre in Glasgow.

They placed it alongside 75 scaled-down stencils etched around the bus in a "reverse graffiti" style artwork to highlight the scale of the positive impact public transport can have on congestion and emissions.

The stunt is part of an ongoing campaign by the operator to encourage people to leave their cars behind for journeys which could be taken by bus.

To encourage drivers to make the shift, First Bus also gave away free single bus tickets to shoppers.

They hoped the campaign would allow car users to clearly see their own journey’s direct impact on the city’s road network.

First Bus wants to show how making small swaps to travelling habits can help to reduce traffic and help reduce the impact on the environment.

Graeme Macfarlan, commercial director at First Bus Scotland, said: “We all know that choosing to travel by bus, rather than relying on cars for every journey, is better for the environment.

“We wanted to show Glaswegians how their travel choices could really help to make a difference, by using a strong visualisation that made people stop and think.

“We chose a busy car park, not only to highlight the environmental benefits of swapping the car for the bus, but to capture the exact audience we’re hoping will come on board and begin to make their ‘modal shift’ – even swapping one car journey per week to a bus can have a profound impact.”
