DemographicsNow now uses Portfolio Guzzler, the most accurate drive time engine available!

What is Portfolio Guzzler?

SRC's Portfolio Guzzler drive time engine accurately retrieves customer demographics within a specified drive time because road network integrity is built into the system. Most drive time products create polygons that deviate from real road networks, arbitrarily cutting through neighborhoods including areas not drivable, which significantly alter the resulting demographics.

The drive time engine utilized by your business intelligence solutions will make significant differences in your decision making. Portfolio Guzzler offers the speed and accuracy you can count on.

How does Portfolio Guzzler work?

Portfolio Guzzler follows drivable road segments by going outward from a point towards the nearest intersection in all drivable directions. As it reaches each new intersection, the system keeps track of the amount of driving time remaining. A buffer is then added to each road segment based on the off road speed and the time remaining to capture the majority population that lives within a very small distance to the road (driveways, parking lots, etc.).

What makes Portfolio Guzzler more accurate than other drive time engines? 1) Portfolio Guzzler follows the road network exclusively, the other engines use grids that cut arbitrarily through barriers capturing the wrong neighborhoods or missing them altogether; 2) Portfolio Guzzler buffers roads using the time in minutes left to drive and the off road speed. More households will be captured in a neighborhood as the time remaining to drive increases.

The following example best demonstrates the methodology differences between Portfolio Guzzler and the competing drive time engine.

4 Minute Drive Time from 1375 Grinnell Street, Waterford, MI.

Differences: Total Population -12% Land Area -46%
Portfolio Guzzler:

10 minute Drive Time around 12165 High Bluff Drive, San Diego, CA

Portfolio Guzzler follows the roads and therefore captures areas off of major thoroughfares and does not cut diagonally through nor grab the perimeter of neighborhoods.

Differences: Total Population 34.27%. Land Area: 17.53%.

Portfolio Guzzler:
Total Population 149,899
Area Sq Mi 55.39
Other Engine:

6 Minute Drive Time around 283 Norfolk Avenue, Park City, UT

Differences: Population 65.41%. Land Area: 41.28%

Portfolio Guzzler:
Total Population 18,607
Area Sq Mi 80.57
Other Engine:
Total Population 11,249
Area Sq Mi 57.03

6 Minute Drive Time around 501 Acoma Street, Denver, CO

Portfolio Guzzler often out performs other drive time products in urban centers because Portfolio Guzzler recognizes that it take twice as long to drive to a point diagonal to a location than it does to follow the distance as the crow flies.

Differences: Total Population -77% Land Area -62%
