3 Lessons That Changed How I Plan Bus Networks

The more time I spend in network planning, the more I realise how many assumptions I once held that no longer serve me. Planning a network that works on paper is one thing. Planning one that works in the real world? That takes a different mindset entirely.

Here are three things I’ve changed my mind about:

1. Vehicle Requirements Matter More Than I Thought
   I used to focus on the elegance of a timetable or the simplicity of a route structure. The truth is, it is just a dream if you can’t justify the number of vehicles needed to run it. Resource limits aren’t there to get in the way of our big ideas, they’re a strategic constraint and I’ve learned they need to be respected. You can’t flood a corridor with buses just because it “feels right.” These days, I start with the PVR and frequency in mind, not as an afterthought.
2. People Will Change Buses
   I used to believe that asking passengers to change services mid-journey was a non-starter. Too risky. Too annoying. Too unreliable. But in a well-designed, high-frequency network with clear information and short waits, people will make that trade. They just need to feel confident they won’t be stranded. Now I see interchange not as a hindrance, but as a tool to make connections that are otherwise impossible.
3. The Data Doesn’t Always Match What’s in Your Head
   There were times I felt sure a certain area would generate strong usage. The roads looked right. The housing looked dense. The routes made sense. But then the numbers told a different story. I’ve learned to listen to the data, even when it contradicts my instincts. And I’ve also learned that not all density is created equal; affluent areas with high housing density don’t always translate to strong ridership.

There are more changes in approach I’ve had over the years, which I’ll cover in future posts, but these three stand out as the ones that reshaped how I approach most network discussions. Planning buses isn’t about drawing lines, it’s about aligning expectations with evidence, and finding a balance between a dream and reality.
