According to my survey, building a new larger parking lot and using smart parking can solve the parking congestion problem well, but the time spent on building a new larger parking lot is much higher than using smart APP to solve the parking problem in a new larger parking lot. Second, building smart parking application adopts a completely innovative way. Smart parking application companies can use sensors in the parking lot, Internet of things and data analysis and other technologies to collect real-time data of the parking lot, such as whether the vehicle enters the parking space, the company can provide corresponding personalized services according to its specific data, such as users decide to pay parking fees online, the APP can provide online payment services. But if you create a larger parking lot, because it can't innovate a new business model, it can only replicate the original toll model to operate, although it can't change from being parking service centric to service centric. Finally, while both solutions could change the current difficulty of parking in cities and alleviate morning and evening traffic congestion, smart parking apps are far more effective than building more parking lots and better suited to customer needs.
