Parkopedia has more accurate parking data than INRIX according to a study comparing the two providers' data for over 50 parking locations in Seattle. The study found that while both providers had accurate data for location coordinates and lot types, Parkopedia provided more complete information than INRIX for attributes like addresses, hours, payment types, rates and restrictions. Providing all available parking lot details, like INRIX, could significantly improve INRIX's data accuracy.

Parking Data Quality Project Seattle June-July 2013 INRIX Confidential
PDQP Summary: Overall Accuracy Parkopedia has the edge over INRIX in overall accuracy. Much of the discrepancy could be removed by simply listing all available information. INRIX Confidential
AGENDA PDQP Project Definition & Goals Methodology Results Detailed Provider Comparisons Recommendations INRIX Confidential
Project Definition & Goals What It Is Conduct site visits for 50+ parking data points in the Seattle metropolitan area to validate INRIX parking supplier data information Goals Measure the accuracy & availability of INRIX parking supplier data compared to real time parking information Compare INRIX parking supplier data to competitor Parkopedia INRIX Confidential
METHODOLOGY INRIX Confidential
PDQP Methodology Selected city: Seattle Selected data providers: INRIX and Parkopedia Number of suitable parking lots from data feeds: 50+ Number of parking lots checked on-site: 50+ total INRIX Confidential
PDQP Methodology (continued) Key criteria checked: - Lot name - Lot address - Phone number - Latitude/Longitude - Lot type - Opening hours - Payment type - Hourly rates - Rate restrictions - Parking restrictions INRIX Confidential
PDQP Methodology (continued) Location of parking lots: - Downtown - Airport - Tourist areas - Commercial hubs Timeframe: On-site checks in June/July 2013 Provider data sources: Combination of provider website, mobile app and data feeds (assuming data was the same for each medium) INRIX Confidential
PDQP Methodology (continued) Evaluation: Provider data is compared against on-site findings. A match of the provider data with the on-site evidence (ground truth) receives the value 1, a mismatch (or missing) the value 0, a partial match the value 0.5. Computation: Based on the accumulatively scored values (1, 0, 0.5) the accuracy of the parking supplier data was calculated for - Overall - Criteria such as address of parking lot and rates Documentation: The results were documented in MS Excel spreadsheets and MS PowerPoint charts INRIX Confidential
PDQP Methodology: Data Acquisition/Evaluation Example results from spreadsheet (INRIX v. Real Time)
RESULTS: DETAILED COMPARISON INRIX Confidential
PDQP Results: Overall Accuracy for Lot address Discrepancies are largely due to - Wrong street or number - No entrance on listed street address INRIX Confidential
PDQP Results: Findings for Lot address Parkopedia performs well in listing the correct address information, often additionally providing several different common names (Port of Seattle Parking Garage, Seattle-Tacoma International Airport Garage) INRIX Confidential
PDQP Results: Findings for Lot address Example of wrong/missing airport parking garage address information by INRIX. INRIX Confidential
PDQP Results: Findings for Lot address Example for wrong address information by INRIX. (See address number on image from MasterPark website) INRIX Confidential
PDQP Results: Overall accuracy for Latitude/Longitude INRIX Confidential Both INRIX and Parkopedia had correct coordinate information available (INRIX provides additional Lat/Long coordinates for the middle of the lot)
PDQP Results: Overall accuracy for Lot type INRIX Confidential Both INRIX and Parkopedia had correct lot type information available.
PDQP Results: Overall accuracy for Opening hours INRIX Confidential Discrepancies are largely due to - Not listing all available information - Partially incorrect information
PDQP Results: Findings for Opening hours Example of partially incorrect information by Parkopedia (Monday) INRIX Confidential
PDQP Results: Findings for Opening hours Example of Parkopedia performing well by listing all the hour/rate information provided by the parking site. INRIX Confidential
PDQP Results: Overall accuracy for Forms of payment Discrepancies are largely due to - Missing information about cash payment option - Not 'cash only INRIX Confidential
PDQP Results: Overall accuracy for Hourly rates Discrepancies are largely due to - Partially incorrect or missing info INRIX Confidential
PDQP Results: Findings for Hourly rates INRIX Confidential Example of INRIX providing accurate hourly rates.
PDQP Results: Findings for Hourly rates INRIX Confidential Example of INRIX providing accurate hourly rates.

INRIX Confidential Discrepancies are largely due to - Partially incorrect or missing information PDQP Results: Overall accuracy for Rate restrictions
INRIX Confidential Example of Parkopedia displaying rates with validated parking for the M-Street Garage. PDQP Results: Findings for Rate restrictions
PDQP Results: Findings for Rate restrictions INRIX Confidential Example of additional information provided by Parkopedia that is not provided by INRIX (early bird and overnight specials)
PDQP Results: Overall accuracy for Parking restrictions Discrepancies are largely due to - Partially incorrect or missing information on maximum park time - Reserved for guests/permit parking/monthly parking INRIX Confidential
INRIX Confidential Example of missing information from INRIX. (Failing to display 10hr maximum parking restriction on weekends that Parkopedia shows upfront) PDQP Results: Findings for Parking restrictions
PDQP Results: Findings for Parking restrictions INRIX Confidential Example of missing data from INRIX that fails to mention a 4hr maximum parking restriction on a 24hr lot (Notice incorrect INRIX address as well)
Parkopedia provides all the information available (early bird specials, overnight rates, validated parking, motorcycle rates etc) Most of the discrepancies INRIX has can be solved by doing the same, by providing the data available PDQP Recommendations
