Intelligent transport

Modern transport — both urban and railway — relies on communication infrastructure capable of continuous operation, resistant to interference, and compliant with industry standards. Signaling systems, traffic control, video monitoring, telemetry, urban lighting, and ITS fleet management all require connectivity that remains reliable every second of the day.

BitStream provides solutions compliant with EN 50121-4, ensuring reliable data transmission and time synchronization for transport and railway systems, maintaining full operational integrity in environments with elevated safety requirements.

For operators of intelligent transport networks (ITS, Smart City), BitStream is a technology partner supporting the development of architectures that integrate traffic lights, passenger-information systems, event monitoring, and IoT device communication into a unified, stable platform.

Security

Devices developed by BitStream ensure reliability and safety even in the most critical situations.

Versatile Applications

BitStream offers solutions for intelligent transport systems (ITS) that collect real-time information about road-traffic conditions — from roads and tunnels to bridges and other transport infrastructure.

Complete solutions

A comprehensive portfolio of secure, high-capacity solutions enabling the use of data-rich ITS applications.

Reliable ICT Infrastructure for Transport

In transport environments, device resistance to vibration, temperature fluctuations, and electromagnetic interference is essential. BitStream switches, routers, and time-synchronization modules are designed for operation in demanding locations such as rail tracks, tunnels, viaducts, and intersections equipped with ITS systems.

With redundant architecture, communication remains stable even during partial link failures, ensuring that traffic-control systems continue to operate according to schedule. Precise timing guarantees correct signal-logic operation and accurate event sequencing in analytical systems.

BitStream also supports operators in implementing solutions that facilitate network scaling as cities grow, integrating new IoT devices and migrating toward Smart Mobility models.

Featured products

Cybersecurity in Rail and Transport

The increasing digitalization of transport infrastructure introduces new risks. Attacks on traffic-control systems, manipulation of communication signals, or transmission interference can lead to serious operational consequences. BitStream develops solutions that strengthen cybersecurity in rail and transport, including communication-zone segmentation, edge protection, anomaly detection, and time-layer shielding against interference.

In architectures integrating signaling, monitoring, public-transport vehicles, and municipal energy systems, maintaining isolation of critical subsystems is essential — and our devices enable precise management of these layers. Properly implemented communication protects against unauthorized access, peripheral-device errors, and the risk of telecommunication disruptions.

Secure Data Transmission in ITS and Smart City Systems

Modern cities rely on distributed telematics systems that generate vast amounts of data — from traffic-control signals to video streams from surveillance cameras. BitStream provides platforms that enable secure data transmission, allowing ITS engineers to remotely manage traffic-light networks, traffic-measurement stations, and street lighting without risking data-integrity loss.

Time synchronization ensures consistent event logs, which is crucial for transport analytics and automated incident detection. Stable transmission enables immediate response to events, dynamic traffic control, and optimization of public transport.

Application

ITS uses intelligent transport technologies such as traffic-light control systems, Variable Message Signs (VMS), automatic license-plate recognition, CCTV security systems, automated incident detection, and applications that collect and process real-time data — including parking guidance or weather-information systems. All these systems require a stable and reliable network with high security and precise synchronization — features delivered by our devices.
