I-CBTC

40 CBTC/I-CBTC Lines in Total, 24 I-CBTC Lines

Product Introduction

Interoperability-CBTC (I-CBTC) is a CBTC system that realizes the interconnectivity of different signal equipment based on unified regulations and standards and the interoperability of trains. The main characteristic of interconnectivity is to meet the interoperability requirement of train and improve the utilization ratio and operation capability of equipment. TCT integrates different signal systems based on the interconnectivity solution of self-developed CBTC so that trains with various onboard equipment can realize seamless, safe, and reliable operation on one or more rail transit lines with different trackside equipment.

Characteristics

I-CBTC is a further upgrade based on CBTC and can reduce the user’s investment and operation cost, improve passengers’ traffic efficiency, and realize resource sharing. With the development of rail transit “from nothing to less” and “from less to more”, many cities in China gradually form a rail transit network structure or basic network. However, the signal systems of different lines are incompatible, which results in cross operation failure, low equipment universality and resource sharing rate, high training and maintenance difficulty and cost, unbalanced passenger flow distribution and large transfer pressure. While I-CBTC can reduce the resource waste of lines, realize resource sharing through overall planning of railway network and has the following advantages:

1. Realize resource sharing of different lines and vehicles, deploy vehicles of other lines according to the passenger flow, improve the utilization ratio, reduce the demand of vehicles from the original single line to the whole railway network and effectively minimize the vehicle purchasing cost;
2. Realize operation dispatching and resource sharing of drivers and crew. Unified operation interface and mode is favorable for overall integration and deployment of personnel and reducing human resource and training costs.
3. Realize sharing of train depot, parking lot, main lines and transfer stations, and reduce the land construction and acquisition for equipment and rails as well as the construction and later maintenance cost.
4. Favorable for realizing network operation of urban rail transit and improving the passenger travel efficiency.
