Abstract:Based on Baidu map and iFlytek, this paper designed a parking guidance information system with func-tions of language interaction and automatic optimization of recommended parking lots. The system recommends parking lots, optimizes driving routes, and induces users to enter and park parking using voice interactive technology according to real-time traffic conditions and parking space around the destination. The data is constantly refreshed during the driving process of the vehicle, and the users are timely reminded by voice when there is congestion on the road ahead. According to the different demands of users, This system optimizes the weight and gives personalized recommendations to customer. The application of this system can not only improve the utilization rate of parking resources, but also improve economic and social benefits.
