Demand, not crashesWhere it asks the most

Nobody publishes a crash map for these roads and this project will not invent one. This is a map of how much steering each two kilometres asks for, measured the same way everywhere.

Route 1095

8.93curves per kilometre — the hardest 2 km on the loop

2.02 km of Route 1095, drawn to its own bounding box. Every mark is a direction reversal the counter scored; the big ones are the 2 hairpins. · © OpenStreetMap contributors

Under 2 curves a kilometre — you can look at the view2 to 4 — steady work, both hands4 to 6 — a steering input every few secondsOver 6 — this is where a tired rider makes the mistake

Dragging a brake down a long descent heats it until it stops converting speed into heat as well as it did. On a small automatic with a drum rear…

Buses and pickups on your line

Route 1095 and the mountain half of Route 108 are two lanes, and the minibuses, songthaews and delivery trucks that serve these towns take a hairpin…

Gravel on the apex

Sand, grit and washed gravel collect on the inside line of a hairpin and at the exit of a cutting. It is the most common surface hazard on this…

Riding after dark

ขี่ตอนกลางคืน

Once the sun is down the circuit has no ambient light at all outside the towns, and a rented bike's headlight is usually a single bulb of unknown age.

Riding in the smoke

ขี่ในควัน

In March and April the measured PM2.5 on this circuit sits above the US 24-hour standard on most days. On a bike you are breathing hard, at volume…

The low sun

แดดต่ำ

Late afternoon on a westward leg in the cool season puts the sun directly down the road. A dusty visor turns it into a white sheet.

Demand is measured the same way everywhere on this network: curves per kilometre in fixed 2 km windows. It says where a road asks the most of a rider. It is NOT a record of where anyone has crashed — no such record is published for these roads, and none is invented here.
