UA Engine

Routing and aggregation engine for ‘Urban Analyst’.

Why?

Urban Analyst Engine aims to be the fastest and most scalable open source multi-modal routing engine. Other notable options include:

  1. “valhalla”, for single-mode routing
  2. “r5” for multi-modal routing

In comparison, the uaengine:

  • Is considerably faster than either of these (see the “benchmarks” vignette);
  • Permits far larger queries (valhalla, for example, is restricted to maximal queries of 2,000 pairwise comparisons, uaengine easily extends to millions of comparisons);
  • Allows true multi-modal travel times to be calculated, with specified, and potentially different, initial and final modes of transport.
  • Automatically returns ratios of multi-modal to private automobile travel times.
  • Includes estimates of travel times with private automobile that are empirically calibrated to extensive data, and are generally more accurate than equivalent times from valhalla or r5.
  • Unlike all other routing engines, UA includes locality-specific estimates of additional times required to park automobiles at starts and ends of journeys.

How?

Usage of this engine is not yet documented. Feel free to open an issue if you’re interested in learning how to use this engine.
