OLE Performance Feed

Objective

InTrans is calculating performance measures statewide for project prioritization by the Office of Location and Environment. These performance measures are calculated on a daily and monthly basis for all INRIX XD segments. An API was created for both feeds using Reactor Feeds (Open Data Service) which allow for querying by time and segment (see feeds below).

Historical data was also calculated for each TMC segment statewide. This allowed for historical comparison in the project prioritization process. Because INRIX recently changed the XD segmentation, it was decided to use TMC segments for consistency in the historical data. A look up file was also created to relate the current XD segments to the TMC segments.

The performance measures calculated include:

· Free flow speed

· Historic average speed for that time period

· Total Hours of delay for that time period against historic average speed

· Total Hours of delay for that time period against Free flow speed

· Average Confidence score for that time period

· Average C value for that time period

· Average travel time for that time period

· Number of bottlenecks for that time period

· Average duration of the bottlenecks for that time period

· Average max length of the bottlenecks for that time period

· Number of events/incidents for that time period

Completed Work

The feeds information is located below. Supporting documentation and data structure has also been developed for each feed.

1. Daily Performance Measures:

URL: http://reactorfeeds.org/feeds/inrix/daily (XML) / http://reactorfeeds.org/feeds/inrix/daily.json (JSON)

We can add the search filters to limit the results. The date's filter should be in the format of "MM-dd-YYYY".

Sample: http://reactorfeeds.org/feeds/inrix/daily.json?code=1450418477&start=08-15-2017

2. Monthly Performance Measures:

URL: http://reactorfeeds.org/feeds/inrix/monthly (XML) / http://reactorfeeds.org/feeds/inrix/monthly.json (JSON)

We can add the search filters to limit the results. The date's filter should be in the format of "MM-YYYY".

Sample: http://reactorfeeds.org/feeds/inrix/monthly.json?code=1450418477&start=08-2017

3. Historical Performance Measures:

URL: http://reactorfeeds.org/feeds/inrix/historical (XML) / http://reactorfeeds.org/feeds/inrix/historical.json (JSON)

We can add the search filters to limit the results. The date's filter should be in the format of "MM-YYYY".
