What does a bus journey actually look like?

A bus spends a surprising amount of its journey not moving. This measures the speed and the distance, and the bit that makes it a bus page: how many times you stopped and how long you spent standing still.

The Stops counter ticks up each time the bus comes to rest for more than five seconds and then pulls away. Stands, red lights and queues all count, because from a passenger's seat they cost the same thing.

Why is the average so low?

A city bus rarely averages more than 12 to 18 km/h across a route, even though it hits 50 between stops. That's arithmetic, not driving.

Compare Moving with Elapsed and it's usually stark. A third to a half of a busy urban route is spent stationary. Bus lanes and signal priority don't make the bus quicker between stops. They cut the standing time, which is where the journey actually goes.

Service Average Between stops
City centre bus 10 to 14 km/h 30 to 40 km/h
Suburban route 18 to 25 km/h 50 km/h
Bus rapid transit 25 to 30 km/h 60 km/h
Intercity coach 70 to 85 km/h 100 km/h
A route averaging 12 km/h hasn't been driven slowly. It's been stopped a lot. So the number to watch on a bus is the ratio of moving time to total time, not the top speed.

How fast can a bus legally go?

Buses are usually limited more tightly than cars, and most have a mechanical limiter as well.

Getting a signal on a bus

A bus is worse for GPS than a train and much worse than a bike. The roof is metal, newer windows are often coated, and city routes run exactly where signals bounce off buildings.

Checking a timetable against reality

Run this for a whole journey and you get the honest version. Real distance, real time, real time spent stopped. It's the quickest way to find out whether a route is genuinely slower at rush hour or whether it just feels that way.

Frequently asked questions

Why is the average so much lower than the speed I see?

Because average includes every stop. A city bus can hit 40 km/h between stops and still average 12 across the route. Compare Moving with Elapsed to see how much was stationary.

What does the Stops counter count?

Every time the bus comes to rest for more than five seconds and then pulls away. It can't tell a bus stop from a red light, and from a passenger's point of view they cost the same.

Why is the reading jumpy in the city centre?

Signals bounce off tall buildings and arrive late, which reads as speed changes that never happened. Turn up the smoothing and watch the accuracy figure.

How fast can a coach legally go?

In the EU and UK, coaches must have a limiter set to 100 km/h. Road limits may be lower, and city buses are often governed well below them.

It reads nothing at all on my bus.

Metal roofs and coated glass both block satellites. Move to a window seat, and upstairs if there is one. If accuracy stays above ±50 m, the phone isn't on satellites.
