Routing and aggregation engine for ‘Urban Analyst’.
Urban Analyst Engine aims to be the fastest and most scalable open source multi-modal routing engine. Other notable options include:
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,uaengineeasily 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
valhallaorr5. - Unlike all other routing engines, UA includes locality-specific estimates of additional times required to park automobiles at starts and ends of journeys.
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.
