IN THE CITY
In 2026, the press of a city in the interior of Rio de Janeiro state pointed to Merus passenger lookup three times: at launch, at the expansion and on days of delay.
Waiting without knowing when the bus comes.
In Nova Friburgo, passengers reported delays and difficulties getting around. The operator pointed to traffic congestion as one of the main causes of delays on the city's lines.
Understand the context
Information for those at the stop.
The Merus lookup began to show lines, bus locations and arrival predictions. Using the phone's location, passengers could also find nearby stops.
Learn about the lookup
The information reached the public.
A Voz da Serra and Portal Multiplix pointed to the lookup in their stories. On days of delay, it was presented as a way to follow the trip.

CONTRACTS AND SUBSIDY
Attach the contract as it is. Merus AI reads the parameters, you approve each one, and from then on subsidy, penalties and scorecard are calculated automatically, trip by trip.

You approve each parameter
No value enters the calculation without review. The manager confirms or corrects each parameter, and the decision is recorded with date and responsible party.

The calculation closes by itself
Kilometers, trips and delays measured in the operation go through the approved rules. The amount payable comes out with a reconciliation statement, trip by trip.

In a first 30-minute conversation, we identify the jurisdiction, the instrument and the decisions that need evidence.
Assess a public scenario STARTING POINT
The questions of those who contract, oversee and report on transport, answered by those who implement Merus.
We start with the contract and the sources your scenario already has.
- Diagnosis We map jurisdiction, contractual instrument, lots, operators and the decisions that need evidence.
- Sources We assess operators' systems and equipment and install Merus telemetry where it is missing.
- Rules and loading Our team configures the contract and loads lines, schedules and fleet together with your team.
- Validation We test measurement, alerts and reports with oversight and internal control.
- 100% functional We stay with you until everything runs. Public information goes live when the public body authorizes it.
Merus teamImplementation · online - The operators already have GPS on the buses. Do we need to install anything?
- Not necessarily. We have native integrations with the main telemetry hardware and assess the operators' systems. Where equipment is missing, we sell and install Merus telemetry.
- Does Merus calculate the subsidy?
- It applies the rules your contract defines and shows the path to each amount. There is no universal calculation: the rule is the instrument's, and the decision stays with the agency.
- Does this replace a legal opinion?
- No. Merus organizes data, rules and evidence; legal interpretation and administrative decisions stay with the public body's officials.
- Can bus arrivals be shown to citizens?
- Yes, in enabled flows: lines, schedules and arrival predictions, with sources and responsibilities defined in the project.
- And school transport?
- We record each student's boarding using the planned method, with purpose, access and data protection in line with the LGPD.
- Who registers lines, schedules and contract rules?
- The Merus team does the loading together with your team: lots, lines, timetables, fleet and contract parameters.
- How long do you stay involved?
- Until the system is 100% functional in your scenario.
FAQ
Frequently Asked Questions
How do you oversee a bus concession?
Merus Tracker compares the contract schedule with the recorded execution of each trip: times, itinerary, mileage and fleet. Trips with no record, deviations and delays beyond tolerance appear with the position, time and source of each data point, so oversight can analyze them and record the decision.
How do you measure the mileage driven?
Merus Tracker calculates mileage from the trips recorded by the project's sources, such as trackers and operator systems, and places it next to the scheduled mileage. Validation criteria follow the contract, and each difference keeps its origin and history.
Does Merus calculate the subsidy?
Merus Tracker can support the calculation and review of compensation by applying the rules the contract defines, but there is no universal subsidy calculation. Rules, sources, validations and responsible parties are defined in each project, and the decision stays with the public body.
How do you report to the court of audit?
Merus Tracker keeps the history of each calculation: the rule applied, the origin of the data, the validations and the decisions, with date and responsible party. This record supports internal control and responses to oversight bodies; analysis and statements remain with the public body.
Does Merus guarantee legal compliance?
No. Merus Tracker organizes rules and operational data within the configured scope, but legal interpretation, jurisdiction, administrative decisions and compliance depend on the public body, the contract and the authorized officials.
Can citizens see when the bus arrives?
Yes, in enabled flows. With Merus Tracker, citizens look up lines, schedules and the vehicle's predicted arrival. Accuracy depends on the equipment, connectivity and project configuration, and publication depends on the public body's authorization.
How do you control school transport?
Merus Tracker records each student's individual boarding using the identification method planned in the project, linked to the trip and the vehicle. Purpose, access, retention and data protection are defined with the public body, in line with the LGPD.
Can operators' data be used?
It may be possible when there is a legitimate basis, authorized access, technical feasibility and quality. Merus Tracker has native integrations with the main telemetry hardware and assesses operators' systems, APIs and files; no specific integration is promised before that assessment.
What happens with personal data?
In Merus Tracker, purpose, necessity, legal basis, roles, access, retention and security are defined for each scenario. The technology does not replace LGPD obligations or the assessment by the responsible public body.
How does implementation begin?
Merus Tracker implementation starts with a diagnosis: jurisdiction, contractual instrument, decisions that need evidence, available sources and responsible parties. Then come sources and equipment, configuration and loading, validation with oversight and internal control, and support until the system is 100% functional.
