Predict risks on the road with historical and real-time accident, traffic, weather and roadway data

Risk Index API

Gain predictive insights into the relative risk & safety of the road with the Risk Index API. Arity has aggregated many data sources and applied our predictive modeling expertise to offer a broad range of predictive data sets to make vehicles and drivers safer.

Arity’s Risk Index allows for the minimization of risk while driving and identifies opportunities to improve the infrastructure.

Getting Started

  • No API key or authentication is required to use the API
  • All methods require that the search area be designated with Well Known Text (WKT), a spatial reference system that uses latitude and longitude coordinates to define geometries on a map

To download the Postman collection or see sample requests/responses for this API, check out our GitHub repository.

Supported Regions

Currently all of California and Illinois are supported, and geographies outside these regions will not return any data.

Methods

GET

getAllRiskIndexByLocation

https://api-beta.arity.com/riskIndex/v1/all

Get all available information about the relative risk & safety of the road at a specified location (e.g., accidents, traffic, risk info, etc.)

GET

getRiskInfoByLocation

https://api-beta.arity.com/riskIndex/v1/riskInfo

Get both static and dynamic predictive risk scores indicating the likelihood, severity, and potential cost for an accident in a specified area. Historical and real-time accident, traffic, incident, weather and other data are used to generate the scores.

GET

getAccidentSummaryByLocation

https://api-beta.arity.com/riskIndex/v1/accidentSummary

Get detailed and summarized historical road accident information for a specified location. Organized by accident type (e.g., rear end, intersection, lane changing).

GET

getFARSInfoByLocation

https://api-beta.arity.com/riskIndex/v1/farsInfo

Get summary of traffic fatalities for a specified location, including dates, causes, weather, road conditions and other information.

GET

getRealTimeTrafficByLocation

https://api-beta.arity.com/riskIndex/v1/realtimeTraffic

Provides real-time traffic information (e.g., speed, congestion) at the specified location. Data is updated every minute.

GET

getHistoricalTrafficByLocation

https://api-beta.arity.com/riskIndex/v1/historicalTraffic

Get historical traffic information (e.g., vehicle volume, speed) for a specified location
