A method for detecting pedestrian traffic by using a Wi-Fi probe. A Wi-Fi probe acquires raw human traffic data by means of capturing media access control (MAC) address data from a mobile device;a data screening standard is used to process the raw data, and a plurality of methods are provided to establish a functional relationship between detected human traffic and actual human traffic;when three probes are used for detection, four spatial layout schemes are given;by combining a specific layout pattern, a data processing method for distinguishing traffic and traffic direction is presented, the same having a high pedestrian detection rate and a high degree of accuracy in detection.

A dynamic pricing method for premium parking spaces with priority given to short-term parking. Said method factors in the number of premium parking spaces, parking demand characteristics of an area, parking space occupancy rates, and so on. A progressively-increasing fee calculation method is used to calculate fee prices for premium parking spaces in a precise manner, and adjustments are made dynamically according to actual situations. This allows vehicles parking for short periods of time to be given priority to the limited supply of premium parking spaces, and thereby increases the turnover rate of premium parking spaces, which enables more drivers to enjoy a parking service that is comfortable and convenient, and that affords a shorter walking time, thus leading to an increase in overall societal efficiency.

Recently, engineering blasting is widely applied in projects such as rock mineral mining, construction of underground cavities and field-leveling excavation. Dynamic mechanical performance of rocks has been gradually attached importance both in China and abroad. Concrete and rock are two kinds of the most frequently used engineering materials and also frequently used as experimental objects currently. To compare dynamic mechanical performance of these two materials, this study performed dynamic compression test with five different strain rates on concrete and rock using Split Hopkinson Pressure Bar ( SHPB) to obtain basic dynamic mechanical parameters of them and then summarized the relationship of dynamic compressive strength, peak strain and strain rate of two materials. Moreover, specific energy absorption is introduced to confirm dynamic damage mechanisms of concrete and rock materials. This work can not only help to improve working efficiency to the largest extent but also ensure the smooth development of engineering, providing rich theoretical guidance for development of related engineering in the future.
