I have noticed that most people only think about toll equipment when toll equipment stops working. A lane freezes. A camera feed goes black. Cars start stacking up, and someone in the control room is on the phone trying to work out why.
By then you’re already losing money. Missed transactions, manual handling, a queue that gets longer by the minute. And the fault that caused it? Usually it had been building for weeks. A power supply running hot, a lens covered in dust, a network link that kept dropping at night.
That’s the case for preventive maintenance for ITS infrastructure. You handle issues when you want before they become big problems at the worst time. It keeps machines working, helps tools last longer, and means your repair costs stop being a bad surprise every few months.
What Is Preventive Maintenance for ITS Infrastructure?
Routine work is the job you do before anything fails. Routine work means inspections, testing, cleaning, calibration, software checks, and replacing parts that are wearing out. Routine work follows the logic of getting your car serviced; you do not wait for the engine to quit on the highway.
Preventive, reactive, and predictive maintenance explained.
Reactive maintenance happens when you only fix something after it fails. At first, reactive maintenance may seem cheap. Over time, reactive maintenance brings many hidden costs: emergency service calls, longer downtime, and hurried repairs.
Preventive maintenance takes place at intervals, such as time, usage, or manufacturer recommendations. Because Preventative maintenance is planned, you can choose when to shut down equipment for service.
Predictive maintenance is even better than preventive maintenance. Predictive maintenance uses real‑time data, like temperature trends, error rates, and device health logs, to predict when a part will likely fail. Predictive maintenance is useful. It only works if you already have good monitoring and clean records. Most operators reach maintenance after establishing a solid Preventative maintenance routine, not before.
How ITS maintenance differs from general highway maintenance
Highway maintenance is mostly about things you can see and touch: pavement, drains, signs, barriers. ITS infrastructure maintenance is a different job. You’re dealing with electronics, networks, and software that all depend on each other.
Faults can hide. A camera may power on perfectly well and still misread plates. One dead switch can take out a whole lane. Firmware and configuration need as much attention as the hardware does. So ITS equipment maintenance calls for people who understand both the electronics and the IT side, which isn’t something a civil maintenance crew is usually set up for.
Why Preventive Maintenance Is Important for ITS Operations
Reducing unplanned equipment downtime
ITS system downtime rarely shows up as one big failure. It’s more like a string of small, annoying things. A lane controller that restarts now and then. A sensor slowly losing its calibration. A link that drops every evening during peak hour. Regular checks pick these up early, and you can fix them in a quiet window instead of mid-rush.
Supporting reliable toll collection
A toll plaza depends on parts. The lane controllers, the readers, the barriers, the classification sensors, and the back‑office software must all work together for a toll plaza to run smoothly. If one part slips, the toll plaza slows down vehicles. Lanes go manual. Keeping them in good shape protects both traffic flow and revenue. This is a big reason operators sign up for a toll system AMC. It means the checks happen on schedule instead of whenever someone remembers.
Maintaining traffic monitoring and incident visibility
A camera with a dirty lens isn’t watching anything. A dead detector or a blank message sign leaves the control room guessing right when they need a clear picture. Cleaning, alignment checks, and quick function tests sound dull, but they’re what keeps your response times steady when something actually happens on the road.
Protecting equipment life and maintenance budgets
Equipment that is kept clean. Used within its proper conditions lasts longer. That is the part. The money part is important too. Doing work on purpose spreads the costs throughout the year. Fixing things when they break happens all at once and usually costs more. In the run, you also delay buying new things.
ITS Equipment That Needs Regular Maintenance
A good plan covers the whole system, including the parts nobody sees from the road.
Toll collection and lane equipment
- Lane controllers and toll lane computers
- RFID/FASTag readers and antennas
- Automatic barriers, vehicle detectors and loop sensors
- Automatic vehicle classification and counting (AVCC) systems and weigh-in-motion units, where installed
- Electronic toll management system (TMS) servers and multi-lane free flow (MLFF) equipment, where deployed
- Toll booth terminals, printers, displays and canopy signals
ANPR cameras, traffic sensors and detection devices
- ANPR and surveillance cameras, including housings, lenses and mounts
- Radar, video or loop-based vehicle detection and counting devices
- Seatbelt and wrong-way detection systems and video-based vehicle profiling units, where installed
- Meteorological and environmental sensors
- Variable message signs and lane control signals
Communication networks, control-room systems and backup power
- Optical fibre (OFC) and wireless communication links, switches and routers
- Servers, storage, video management and toll management software
- Integrated command and control surveillance systems, control-room workstations, video walls and operator consoles
- UPS units, batteries, generators, solar-integrated power supplies and earthing systems
Pay extra attention to power and networking. So much hangs off them that one tired battery bank or one damaged fibre link can take down a surprising amount of equipment in one go.
How to Build an Effective ITS Preventive Maintenance Plan
Keep it simple enough that a field team will actually follow it. If you’re drafting a highway infrastructure maintenance contract or AMC, these are the things it should cover.
Equipment inventory and inspection schedules
Log every fault: note down the time, the place, what it looked like, and what caused it. Decide ahead of time who will take over if it isn't fixed quickly,y whether that is an engineer or the OEM. Once a repair is completed, test it. Record the closure. Do not just assume it worked. That habit reduces repeat visits. After a few months,s you will have a fault history that tells you something useful.
Fault logging, escalation and repair verification
Log every fault: note down the time, the place, what it looked like, and what caused it. Decide ahead of time who will take over if it isn't fixed quickly, whether that is an engineer or the OEM. Once a repair is completed, test it. Record the closure. Do not just assume it worked. That habit reduces repeat visits. After a few months, you will have a fault history that tells you something useful.
Spare-parts planning and maintenance documentation
Waiting weeks for a part can turn a problem into a long downtime. It’s better to keep a stock of items such as power supplies, network switches, readers and camera units. You should base your stock levels on what has failed in the past and how long it takes to get replacements. Also keep all your paperwork up to date. That includes checklists, service reports, configuration backups, firmware versions, and build drawings. You’ll need all of them during the audit or when handing over the system.
Monitoring uptime, MTTR and recurring faults
Three numbers are enough to start with. Uptime tells how available lanes, cameras, and key systems really are. MTTR, the time to repair,r tells how fast faults get sorted. Recurring faults deserve a look because the same problem showing up again and again usually points to something deeper, like power quality, the environment,t or a bad installation. I find that reviewing recurring faults regularly lets me see where to change the schedule and where to spend.
Common ITS Maintenance Challenges on Indian Highways
Operators here run into a familiar list of problems.
Heat, dust, monsoon humidity,y and lightning are tough on electronics. Voltage changes and power cuts hurt machines and ruin data, ta especially where backup power isn't strong. Places are usually away from each other so getting a technician there fast is not easy. Many corridors have equipment from companies and different years, which makes fixing and getting spare parts harder. Records about equipment and past service are often not good. People who know electronics, networking, and software all together are not easy to find. Stealing cables cars hitting equipment and people messing with it are always a danger, along open areas.
Any serious approach to ITS maintenance services in India has to deal with all of this honestly. That means response commitments that are realistic, the right spares in stock, and trained support close to the site.
When Should Highway Operators Review Their Maintenance Strategy?
If you recognise a few of these, it’s probably time:
- Faults are rising, or the same ones keep coming back
- Lanes or cameras are often out of action
- Repairs drag on because spares or skilled staff aren’t available
- Warranties are running out, or your AMC is close to expiring
- You’ve added a new plaza, corridor, or system upgrade
- Audits or revenue reconciliation point to data gaps or lane losses
- Maintenance costs jump around from month to month
Don’t wait for a major failure to force the conversation. Reviewing early gives you room to move from constant repairs to a planned routine.

Frequently Asked Questions
What is preventive maintenance in ITS?
It’s scheduled work, such as inspections, testing, cleaning, calibration, software checks,s and part replacements, done before equipment fails. The aim is to catch problems early so they don’t interrupt service.
How often should ITS equipment be inspected?
There is no answer that fits every case. The decision depends on the equipment, the instructions from the manufacturer the conditions at the site, and how critical the asset is. For example, toll lane equipment and cameras are usually inspected a month or once a quarter, while detailed servicing is performed less often. Backup power systems and network gear may have their own maintenance schedules. Whatever plan you choose, write the timing clearly in your maintenance contract.
What is the difference between preventive and predictive maintenance?
I have noticed that preventive maintenance happens on a fixed schedule regardless of how the equipment is actually performing. I have also noticed that predictive maintenance uses real-time data or records to predict when a failure might happen. Work is only done when the equipment truly needs it. Predictive maintenance depends on monitoring and detailed records. That's why many operators start by building a preventive maintenance routine first.
Which ITS components require regular maintenance?
Nearly all of the devices are involved. The toll lane equipment, the readers and barriers, the vehicle classification and weigh‑in‑motion systems, the ANPR and surveillance cameras, the traffic sensors, the message signs, the networking gear, the servers, the control‑room systems and the UPS and backup power. Power and communications need attention because so many other devices depend on power and communications.
How can maintenance reduce toll-system downtime?
By catching parts and planning repairs when traffic's low, by keeping spare parts ready and by testing every repair properly.
By tracking how long the system works how long each repair takes and how often the same problems happen you can see where downtime comes from so you can fix the problem and stop guessing.
What should an ITS maintenance plan include?
An equipment schedule list helps check equipment records for problems. Equipment schedule list also tells what to do when problems happen making sure repairs are fixed. Planning for parts keeping records and measuring how well things work, such as how long machines run and how long it takes to fix them are all included. Equipment schedule list explains how fast people must respond, how to report things and who is, in charge of each task. I notice that equipment schedule list is especially important when dealing with a highway infrastructure maintenance contract or a toll system service agreement.
