Poryos2026
A benchmark family of time-dependent routing instances built from real city road networks.
Poryos2026 is a benchmark family for time-dependent vehicle routing. Instead of the usual synthetic traffic constructions, its congestion is derived from real city road networks taken from OpenStreetMap, across five cities (Lyon, Paris, San Francisco, Hong Kong, and Tokyo) and six sizes from 10 up to 1000 customers.
The headline set is 360 time-dependent TDVRPTW instances (more if you count the TDVRP view and the static projections). Each instance ships with a best-known Duration solution, seeded by Kayros anytime campaigns run on the Grid’5000 cluster. The benchmark data is released under ODbL 1.0, in keeping with its OpenStreetMap origin.
It lives in the MAMUT-routing catalog and is exposed through the mamut-routing-lib library as BenchmarkName.PORYOS_2026.
