Public transport is often used as an alternative to peak-hour traffic, but it should be embraced just as much during off-peak times.
Getting more passengers on off peak and weekend services gets the most out of capital investments already spent, such as railway lines, bus stops and vehicles. A bus has already been purchased so there is no extra cost to run it during off-peak times except for the driver and fuel, but the trip will earn money from fares.
Good off-peak services also gives peace of mind to peak hour commuters that should they need to come to work earlier or later, go home early, stay behind or do an errand that services are available for them at that time.
It also offers an alternative to driving to the city because while traffic isn’t bad, it will become an issue in the future, and parking is still a problem. The city is easy to serve well by public transport.
Trains run every 15 minutes all day everyday and some trips are standing room only, but most buses only run every hour during off-peak and so are unattractive to travellers with cars. Even major bus routes have a long way to go on weekends with only services along Beaufort St and on the Circleroute between Fremantle and Southlands running every 15 min on weekends.
In conclusion, off-peak public transport is a good use of infrastructure and fleets that have already been bought, and although Perth is doing well on this matter with its trains, we could improve, especially on buses.
