Fewer Cars in Bus-Only Lanes Creates Faster Headways

Enforcing no-car rules on dedicated bus lanes has been proven to increase bus efficiency in a bus rapid transit system in Indonesia.

The Transjakarta BRT system in Jakarta has seen headways improve since local police began cracking down on car drivers for using bus-only lanes.

"The sterilization is considered effective in improving Transjakarta bus services, indicated by the increase in the number of passengers reaching an average of 18 percent and the faster headway by 2-5 minutes per bus than the previous of 5-10 minutes; thus reducing the amass of passengers. In addition, the compliance level of road users of both public and private motor vehicles also increases."

Lane widths and Exclusivity

It occurred to me last week when studying dimensions for buses, trucks and cars that you could make Bus lanes excluvie by providing a six foot wide grassed or raised strip in the middle of the bus lane. The width for buses is around eight feet, while the width of cars is around six. You'd only need full pavement where you expect the buses to enter or exit the bus lane.

Good for landscaping... but for operations?

There is every opportunity for good landscaping. I am not sure it would be appropriate to try controlling access, though. I would be very concerned it did not leave enough margin for minor driver errors.

No transit agency would want to have to go pull a bus out of the mud because a driver had to scratch his nose!

2 ideas for the nosescratcher problem

Use something like Grasscrete or permeable pavers for the middle of the lane. Something than can support a bus from time to time.

Use rumble strips, road studs, or even 6" curbs to inform the driver that they are steering off course.

I believe Cambridge and Adelaide has LOS A Bus Tracks for their trunk lines. Their bus tracks require guide wheels to conrol the steering, though.

If it supports a bus, it will support cars

A bus track set-up might work.

The pavers, though, would probably eliminate most of the intended purpose of preventing access by personal vehicles, wouldn't they?
