automated parking 2014 For more Solutions visit velocity 29 Dyck says, "With the new system, our park- ing enforcement officers don't have to have prior knowledge of downtown. Training is mini- mized. In fact, we've been able to cut training from one month to two weeks or less." Much of the training is now focused on system operation and calibration, which must happen at the beginning of every shift, and requires from 5-10 minutes to ensure positional accuracy. Benefits/ROI For the CPA, a large part of its Return On In- vestment (ROI) will come from the time saved by parking enforcement officers who manu- ally review and place vehicles in the appropriate parking zones. Prior to the SPAN system, the officers spent 4-5 hours per day reviewing images to deter- mine the correct GNSS locations. As many as 1,400 parked vehicles were mislocated due to multipath errors on any given day. Now the number of mislocated vehicles is down to a few hundred—and the time spent reviewing and po- sitioning the parked vehicles that are mislocated is down to 1-2 hours instead of 4-5 hours. CPA estimates the ROI for the SPAN systems will be less than two years. Dyck says, "Besides the time savings, the im- provement in accuracy has been a great morale booster for our agency. Hours and hours looking at a screen to verify vehicle locations is tedious work. With that time savings, I've been able to reposition one full time parking enforcement of- ficer to other tasks." Management Efficiency An unexpected benefit of the SPAN solution for the CPA has been increased revenue. Dyck adds, "We return all of our net revenue to the city. The more efficiently we are able to enforce parking regulations, the more revenue we return to the city, which is ultimately used to build or repair infrastructure." Also, while the community is not aware of the technology that the CPA has implemented, they might be aware of the increased accuracy of the data collected, which contributes to an overall rise in the CPA's overall enforcement system credibility. Dyck says that he's seeing fewer court appeals and fewer hassles for individuals questioning parking tickets. "When the SPAN-enabled sys- tem takes a picture of a car, 99% of the time that car is in that zone," he says. "This is particularly important when tickets are appealed at court. When presented with accurate GPS referenced location and photo evidence, we get more guilty pleas, and the Court itself has an increased as- surance that the technology that produced the tickets is legitimate." The CPA's goal is not to ticket people parking in the city but to encourage higher compliance. Internal operational goals are to minimize time spent per citation including manually reviewing vehicle images for those vehicles that can't be placed. "We try to make parking as convenient and easy as possible," concludes Dyck. "The latest technologies help us do that with improved efficiency and accuracy of data. In an urban corridor such as Calgary, the SPAN technol- ogy certainly delivers a more efficient, accu- rate solution." The autoChalk mobile user interface visually informs the user as to potential violations. While the user is driving an audible "beep" indicates to the offi cer that a potential violator has been found.
