CAD/AVL + RTPI is at the heart of modernizing urban mobility. If you are on the Somayar blog, the Moroccan leader in ticketing and transport solutions, it is certainly to better understand what it is all about, and above all, how this tool optimizes the daily management of public transport networks. We answer all your questions in this article. Happy reading!
What is CAD/AVL + RTPI ?
Let’s start at the beginning: decrypting this essential acronym used in tenders and technical meetings. In French, SAEIV stands for Système d’Aide à l’Exploitation et à l’Information Voyageurs, which translates internationally to CAD/AVL + RTPI.
In other words, it is the true brain behind transport network management. Thanks to its deployment, local authorities and operators can:
- Supervise fleet operations in real time
- Accurately analyze the actual transport service provided (routes, delays, ridership)
- Broadcast reliable and instant information to passengers (on board, at stops, and on smartphones).
A true hub of technology, this system facilitates coordination between all mobility stakeholders and drastically improves the Quality of Service (QoS). It is an essential tool for boosting the attractiveness of public transport.

The 3 Major Benefits of CAD/AVL + RTPI
1. Boosted Operational Efficiency
One of the major assets of CAD/AVL + RTPI is real-time supervision. In the event of a vehicle incident or a line disruption, operators are immediately alerted and can react without delay.
What were the actual arrival and departure times?
Did the bus leave its depot at the scheduled time?
Did the bus leave its depot at the scheduled time?
Which lines experienced delays or ridership peaks?
This is where our CAD/AVL solution steps in HorizonIt provides both a comprehensive, real-time overview of your network and a detailed analysis of your data. This empowers teams to make informed decisions to adjust frequencies, optimize resources, and generate reliable reports comparing scheduled versus actual service.
2. A Transformed Passenger Experience
On the user side, CAD/AVL + RTPI radically transforms the travel journey thanks to two complementary facets:
The "CAD/AVL" aspect guarantees a more punctual and better-adjusted service
The "RTPI" aspect offers total visibility over the journeys.

It is to meet this specific need that we developed Tarik-GO. Via this dedicated passenger information application, users can track their bus location in real time and anticipate potential delays. They travel with much greater peace of mind.
To take the seamless user experience even further, the integration of our 7afilati mobile application allows passengers to purchase their tickets, top up their prepaid cards, or manage their subscriptions with ease. Connected to our global E-Ticket Bus system, passenger satisfaction skyrockets. In fact, studies prove that having access to real-time information reduces the user's perceived waiting time by 30%!
On board and at stops with our partner Hanover Displays: In partnership with the world leader in passenger information systems, Somayar deploys high-resolution LED destination signs (up to 30 times sharper than standard displays) and dynamic TFT screens triggered by GPS to announce the "Current Stop" and "Next Stop", ensuring a stress-free journey.

3. A True Co-pilot for Drivers
The CAD/AVL system integrates the on-board driver terminal. Installed in every bus, it forms the operational core. Thanks to our system's intelligence, it manages automatic station detection via GPS and automatic trip changes without any manual intervention from the driver.
This terminal also enables real-time ticket sales (single tickets, student or civil servant subscriptions) and receipt printing. By reducing fare evasion and automating complex tasks, it simplifies drivers' daily routines and improves their working conditions on the ground.
What about private shuttles?
CAD/AVL + RTPI is not just reserved for public urban transport! When a company or an institution sets up a private shuttle fleet for its employees, it has every reason to supervise it. Tracking vehicle arrivals allows employees to know exactly when to head down, thereby encouraging the use of this shared transport mode over individual cars.
The Technology Behind the Somayar Ecosystem
One of the major challenges of a successful CAD/AVL + RTPI system is data integration. The unique advantage of the Somayar ecosystem lies in its modularity and complete interoperability: our SAE Horizon platform communicates natively with our E-Ticket Bus ticketing system.
This allows the cross-referencing of operational data (high-frequency geolocation) and ridership data (revenue, validations) on a single, unified interface, without multiplying the on-board hardware. Furthermore, our solutions integrate standard mobility data formats (SIRI, GTFS, GTFS-RT).
Our solution also enables the integration of high-value-added auxiliary modules: automated passenger counting (APC), on-board video surveillance (CCTV), passenger Wi-Fi, and safety systems (automatic engine fire suppression).
