First implement- ed almost seven years ago, the web-enabled ParkPlus system makes it easy for customers to pay for parking with pay machines or by cell phone while a GPS-enabled digital chalking and License Plate Recognition (LPR) system helps parking enforcement officers quickly and accurately detect parking non-payment violations. In recent years, Calgary has emerged as one of Canada's corporate headquarters with a growing economy that thrives on oil and gas, tourism and high tech manufacturing. Eco- nomic and population growth has facilitated the construction of an increasing number of high rise steel and glass buildings along Cal- gary's narrow streets. Unfortunately, increased multipath errors during parking zone checks diminished the parking enforcement system's reliability and efficiency. The tight urban corridors can throw GPS positions off by 500-600 metres or more, creating considerable work for enforce- ment officers charged with reviewing each potential parking violation for positional accuracy. Looking for a way to improve data ac- curacy and save time and money, the CPA agreed to test a NovAtel® SPAN® Global Navigation Satellite System (GNSS) plus Inertial Navigation System (INS) solu- tions on one of its city parking enforce- ment vehicles. The improvement in po- sitional accuracy was so impressive that within three months, the CPA had in- stalled the SPAN system on all of its city- based parking enforcement vehicles—and cut multipath errors to 1% saving consid- erable time, money and boosting morale throughout the agency.
