Bike lanes fail at junctions, which is where the collisions are
A protected lane between junctions is straightforward. Protecting the point where paths cross is the actual engineering problem.

Frequency is the only transit statistic that matters to a passenger
Networks are marketed on speed and length. Riders experience waiting, and waiting is set by frequency.

Metro stations are designed around the walk, not the train
The train is the easy part. Moving several hundred people from a platform to a street in ninety seconds is the design problem.

Dwell time is where a bus route loses its speed
Buses are slow less because of traffic than because of the accumulated seconds spent stationary at stops with the doors open.
Transit
A bus lane is only as good as its last hundred metres
Lanes that end before the junction hand the bus back to the queue at exactly the point where the queue exists.
Transit
A transfer is the point where a network loses passengers
Every change of vehicle is a decision point, and a meaningful share of people decide not to make the trip at all.
Transit
Stop spacing is a trade between the walk and the ride
Closer stops shorten the walk to the service and lengthen every journey on it. Both effects are real and they point opposite ways.
Transit
Step-free access is a network property, not a station feature
A lift at one end of a journey is useless without one at the other. Accessibility is measured in complete trips or not at all.
Transit
Fares are a network design decision disguised as a price
How a system charges determines which journeys people make, which routes fill up and whether the network functions as one thing.

Trams and buses differ mainly in who owns the road space
Most of the performance gap attributed to steel wheels comes from priority, platform design and permanence rather than from the…
Transit
Ridership forecasts miss in predictable directions
Transport models are built on assumptions that fail in known ways, and the failures cluster rather than cancelling out.

Bike parking is the cheapest capacity a station can add
A secure rack extends a station catchment from a ten-minute walk to a fifteen-minute ride, for the cost of a few metres of pavement.
