In-vehicle systems

Our vehicle logic unit, the Medius, provides a nexus to allow Connexionz’s core to interface with multiple and disparate technologies commonly found on a vehicle or vessel. Part of this technology is the Automatic Voice Annunciator System (AVA), which uses text-to-speech functionality. The Medius is the integration point for all the disparate technologies on your vehicles and provides the video processing power to drive your 1080p infotainment displays.

Instant updates

Our automatic vehicle location system can update your vehicle locations up to once every second. We use all that glorious data to generate to the minute accurate arrival times as well as reports for your team.

Support for drivers

Our MDT allows your drivers a handy tool to log in and out, to see how far they are into a route, keep track of fare patronage, bike rack and wheelchair hoist usage, and send and receive messages from your dispatcher. VOIP and LMR integrations also allow your drivers to talk to your dispatcher. Safety features minimize distractions while they are driving.

Commitment to partnership

We are committed to your short, medium and long term success. Our customers rave about our responsiveness, our commitment to preventative maintenance, our passion for listening, understanding and meeting their evolving needs.

Fantastic Reliability

Our cloud systems have better than 99.9% uptime, our proprietary hardware has mean time between failures in excess of 10 years.  We're serious about carrying out preventative maintenance, we design our systems for automated health checks.

Standard connectivity

At the heart of our on-vehicle system is our powerful Medius VLU (Vehicle Logic Unit), which gives us the ability to bring all the systems together in one place. It supports Audio Voice Announcements, Next Stop Announcements, Headerboards, Bus Stopping, Destination/Header signs, Rider Infotainment Displays, Rider Wi-Fi, Traffic Signal PriorityAutomatic Passenger Counters, Engine Diagnostics, Duress Buttons, and Multimedia Displays. Our Medius supports a number of connectivity standards including, J1708, CAN, RS485, USB2, HDMI, and Ethernet.

Compact size

Our Medius VLU is only about the size of a mini-PC. Its compact design makes it popular with our technicians and bus manufacturers. 

It's popular because our Medius can be installed in overhead compartments, behind the driver's seat affixed to a bulkhead, or within an equipment cabinet. The Medius G2 has dimensions of 140 x 120 x 55 mm and weighs only 710 grams.

Handy when there’s very little space for additional technologies.

Low failure rates

Our proprietary hardware has an MTBF of over 10 years and our software systems have an uptime percentage over 99.99%. In the unlikely event of an outage, our responsive support desk is quick to answer your call for assistance and resolve it without any drama.

I am a...

Often the space aboard a vehicle is extremely limited and awkward to access. Enjoy the convenience and time-saving provided by our compact Medius VLU. We've packed it full of integrations and functionality so that you don't have so many individual devices to install.  We've minimized the need for proprietary cabling so finding a compatible cable is much easier.
The Medius VLU has a mean time between failure (MTBF) of well over ten years. That reliability means less disruption to operations, which translates to greater confidence in your system, a key ingredient to building ridership. Better reliability also saves you from needing a larger fleet size to cover the same services during project deployment. Our compatibility with industry-wide standards allows you to use off-the-shelf onboard systems.

Customer and partner reviews

"In 2006, when we set out to find a replacement ITS system, I said I wanted a partner, not just a vendor. Now that I’m retiring, I wanted to call you and let you know, I’m glad to say we found that partner, it was you.”

- Steve Pont, COO of Eastern Contra-Costa Transit Authority
