Introduction

Since 1900, Métro de Paris with its extensive network of 16 subway routes has served Parisians and many visitors by providing a quick, efficent way of reaching the destinations that define Paris's culture, economy, and history. Service across the network is provided by a diverse fleet of metro subway cars, with each fleet having a different configuration of doors. 

A key concern at Metro de Paris is rider safety while awaiting trains on platforms. Therein lies the challenge: to improve platform safety, traditional platform doors would work only if the car fleet is uniform, and if stopping is precisely aligned with platform door openings.
To improve safety and service, Metro de Paris chose STraffic to install Vertical Platform Screen Doors(VSPD) at select stations. Instead of opening horizontally, STraffic developed an innovative solution that opens vertically, like a garage door, to create an open, 8m space for boarding. The solution accommodates differences in subway card door configurations and offers protection for riders, while easily adapting to a variety of station spaces in European railway by virtue of its compact design.

VPSD Pilots

Gare De Vanves Malakoff Station, Metro de Paris to assure an optimal design for Metro de Paris, STraffic entered into a technical implementation agreement with the Korea Transportation Technology Institute.

Design options output produced by domestic suppliers was submitted to SNCF through a consortium established to manage the design and delivery of the VSPD solution. With safety, a paramount concern, the VSPD design includes LED displays and audible alarms to alert riders of VSPD opening/closing, as well as features aimed to support efficient operation and maintenance of equipment.
VANVES MALAKOFF station was chosen as a pilot site because of the volume of riders and because of three different metro types of cars stop there. Only about a quarter of the platform was installed through this pilot operation. Additional projects will be discussed in the future after determining the suitability and stability of the Paris railway environment. SNCF uses alarm sounds and LEDs to warn passengers about the movement of VPSDs and to prepare for more self-managing through maintenance training.

Solution

To date, installation first order stairs and dynamic safety tests are complete. Coutomer acquisition testing is complete, the VPSD will be test-run for 12 months. If sucessful, STraffic's VPSD will be registered with SNCF as an exclusive solution for installation for riders' platform safety.

VPSD Solution, Our Growth Engine

STraffic participated in the International Exhibition on Rail Vehicle and Transport Technology (InnoTrans 2022) in Berlin, Germany, marking our first appearance since September 2020 due to COVID-19. As a consortium company, we showcased our VPSD and technology to highlight our achievements and innovative solutions. A representative from the exhibition noted, “During this event, representatives from railroad authorities across Europe, Saudi Arabia, India, and other countries visited our booth, engaged in consultations, and participated in in-depth business discusthe sions about the implementation of VPSD.” Through the VPSD initiative, STraffic has gained recognition for its rail safety technology. We aim to further strengthen our position in the global market by provid-ing innovative solutions that enhance rail safety and efficiency. These advancements will act as a solid growth engine for STraffic’s international business.

Result

STraffic’s Vertical Platform Screen Door (VPSD) is a top-down screen door system suitable for various train types, regardless of the train’s size and shape. This solution helps ensure passenger safety and increases the efficiency of rail operations. The VPSD’s main feature is its closing method, which allows doors to move up and down, unlike the existing left and right screen doors. This method can be used for various train types and helps improve railway operations by preventing passengers from falling onto the tracks, ensuring safety when

boarding and exiting, and avoiding operational delays due to congestion. In particular, STraffic is recognized for its unique technology in the safety field, both domestically and internationally, as we obtained a SIL4 certificate. SIL4 represents the highest safety integrity level of internationally recognized safety standards. This certification indicates that STraffic’s VPSD system meets the safety requirements necessary for the global market. With the SIL4 certificate, STraffic has fulfilled the requirements for supplying products to the international

railway market, including Europe, and has also gained a competitive advantage in overseas markets.

1. Safety and Reliability:

   • The VPSD system has demonstrated high levels of safety, effectively preventing accidental falls, suicide attempts, and homicides by creating a secure barrier between the platform and the tracks.
   • The system’s reliability has been confirmed through continuous operation without significant issues, ensuring passenger safety and smooth train operations.

2. Operational Efficiency:

   • The VPSD system has contributed to improved operational efficiency by reducing platform congestion and minimizing delays caused by overcrowded platforms.
   • The system’s adaptability to different platform configurations has been validated, allowing for seamless integration into various railway environments.

3. Passenger Feedback:

   • Passengers have reported increased feelings of safety and comfort due to the presence of the VPSD system.
   • The non-intrusive design of the VPSD has been well-received, as it does not obstruct the view or movement of passengers.

4. Environmental Impact:

   • The VPSD system has helped in reducing noise levels and improving air quality on platforms by creating a barrier that minimizes the spread of dust and pollutants.
   • The system’s energy-efficient design has contributed to lower operational costs and reduced environmental impact.

Overall, the pilot tests have confirmed the effectiveness and benefits of STRAFFIC’s VPSD system, paving the way for wider implementation in various railway networks around the world.
