Parking sensor data guide

This document describes how transactional parking sensor data is collected and processed for analysis in the SFMTA’s SFpark data warehouse, particularly for the purpose of conducting demand-responsive rate adjustments.  Additionally, it explains the assumptions and decisions made when interpreting and analyzing the data.  The document concludes with a guide to be used in conjunction with…

Parking sensor technology performance evaluation

As part of the SFpark pilot, the SFMTA used a network of in-ground parking sensors in 8,200 on-street parking spaces. The sensors used for the SFpark pilot were provided by StreetSmart Technologies (now known as Fybr). These sensors utilized a magnetometer to detect when vehicles entered and exited a space. The primary purposes of these sensors were…

SFMTA parking sensor data storage and communication standards

These are the XML protocols that the SFMTA has developed with parking sensor vendors to receive parking sensor data. These XML standards should enable IT developers to reverse engineer the SFpark operational data store, reducing the time and money necessary to implement that technical ability of an agency to receive real-time parking data.

Changes to SFpark availability feed and mobile apps

The parking sensors used to determine real-time on-street parking occupancy in the SFpark pilot areas will be deactivated on December 30, 2013. The SFMTA will continue to provide real-time parking availability information for SFpark garages as well as pricing information for on-street spaces in SFpark areas. The SFMTA will also revise the SFpark website and mobile apps to…
