Scheme Background

In 2015, the national expressway networked ETC system was offic∏ially launched. The implementation of ETC is an effective> way to solve the congestion of highway toll stations and improve₹ the efficiency of highway traffic. ETC is an important measure to promote transportation energy∏ conservation and emission reduction and save land and™ management costs. It is the realistic need to adapt to theπ networked management of highways and achieve the overall benefit of road n etwork. ETC is also an important carrier to vigorously pro‌mote the development of the "Four Transports". In order to give ±full play to the scale merit of ETC, the Ministry of Transpoγrt has organized the national ETC networking work.

XX Expressway Management Office is responsible for the construction a↑nd operation of networked ETC platform, network and data center of Tianjin Expressway. The netw¥orked ETC of Tianjin Expressway falls into three management mode★s, namely Tianjin Expressway Networked Toll Collec≤tion and Settlement Center, Tianjin Expressway sub-centers and Tianjin Expressway toll stations. ≈The settlement center, segment sub-centers and toll stations have all adopt fault₹-tolerant servers, with the stability and security reaching 99.9999%.

Description of Scheme Value Points

1. The system stability of fault-tolerant server reaches 99.9999%; the system is designed for εpreventing downtime and data loss; online upgrade is supported to reduce planned dow→ntime; customized management interface in Chinese is γeasy to operate; centralized management and O&M are supported.

2. High availability makes the maintenance similar to that of a stand-alo↓ne system, with no professional training required; mainstream windows/Linux systems are su¥pported, redundant power supply and customized mailing functions ar×e available, which is convenient for timely maintenanc✘e.

3. Load balancing maximizes the utilization of hardwar e resources.

4. Virtualization is supported, so as to facilitate the subseαquent deployment and expansion of various applicat≠ion systems.

5. The highly integrated networked toll collection data →center can integrate and deploy various key production systems, management sy₽stems or traditional IT applications, including SQL, MAIL/WEB/DNS DOMAIN, fin ance, CRM, supply chain, EHR, etc.

6. Fault-tolerant server hardware and system software are the most cost-efficienσt.
