Baidu created an integrated intelligent parking management platform with high-level video, PDA inspection, Parking Guidance Information System (PGIS), closed parking payment system technologies in Zhuzhou, Hunan Province. This met the needs of users to quickly find parking spaces and pay parking fees.

The "Zhuzhou Intelligent Parking System" has effectively improved overall parking efficiency and reduced traffic congestion by shortening parking duration and driving distance. As a result, the system has produced significant benefits in terms of carbon reduction. Upon calculation, the average daily turnover rate of the parking lot may be increased from 1.3 to 6 sets/day, the average daily utilization rate of parking spaces may be increased to 62%, and the average daily carbon emissions in each parking space reach 119.14g. Phase I and Phase II of Hunan Zhuzhou Intelligent Parking Project have been completed and putuse, the average annual carbon emission reduction per parking space reaches 204.31 kg. Calculated based on 3,368 parking spaces in 46 parking lots, the total carbon emission reduction is 688.12 t/year, which is equivalent to the carbon dioxide absorbed by 37,600 trees.
