# UA Engine

Routing and aggregation engine for ['Urban Analyst'](https://www.urbananalyst.city/).

## 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](https://github.com/valhalla/valhalla)

2. ["r5" for multi-modal routing](https://github.com/conveyal/r5)

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.
