Jieshun ranks first in market share. The main reason is that Jieshun is the first company in China to develop a parking charging system, mainly focusing on IC card charging. In recent years, due to its reluctance to leave the IC card market, As a result, its entrance and exit video toll collection system has fallen far behind. There have been no notable major projects in the past few years, and Jieshun has focused its main energy on upgrading the old system. In fact, Jieshun's upgrade is just constant patching, which makes the system very unstable. Although Aike only started to enter the video entrance and exit charging system in 2014, it has established a strong software development team and has a very high starting point. It is currently developing very rapidly and has super-large projects across the country. For example, the Baiyunchang project has more than 170 and more than 340 entrances and exits. In addition, Aike's software platform is directly connected to the tone traffic management system, so many smart projects have been developed. For static traffic in the city, a large number of integrators come to Aiko to bid for software. Aiko's software platform is at least currently the best in the country. Due to its almost free policy, ETCP has captured almost half of the market in recent years. However, because it does not make hardware itself and obtains goods from manufacturers, the machines are patchwork and the software has numerous bugs, which has led to complaints from users. Others such as PP, kitten are similar to ETCP. In addition, we also want to talk about one company, Ketuo. This company is equivalent to a troublemaker in the industry. It engages in vicious competition with low prices and low quality, resulting in a notorious reputation. Fuji is okay, but not specialized. To break it down, Aike only provides entrance and parking space guidance and roadside parking, which can be considered very professional.
