Passenger car probe data
See how your entire road network moves, in real time and over time.
Smart traffic insights without sensors
Passenger car probe data offers a complete, sensor-free view of mobility across cities, regions, and corridors, all powered by GPS signals from in-vehicle navigation systems, navigation apps on mobile devices and fleet systems We deliver unmatched visibility into live and historical traffic speeds, congestion, and traffic patterns, from freeways to residential streets.
Intelligence that scales across every network
What makes passenger car probe data powerful?
- Full coverage: Freeways, arterials, collectors, locals
- No hardware required: 100% infrastructure-free
- Live + Historical: Second-by-second updates, up to 10 years back
- High precision: Segment-level detail down to 100 feet
Over 60 billion GPS observations are collected daily, giving you a rich, continuously updated traffic dataset at city scale.

Live and historical data at your fingertips
Travel times and speeds
Provide live travel times, speeds, and delays along pre-defined routes or zones, providing real-time situational awareness for traffic operations and incident response.
Event/Incident detection
Deliver live reports of traffic incidents, including accidents, road closures, construction, and congestion, supported by map overlays and flexible integration options.
Intersection performance measures
Deliver real-time signal performance metrics, including split failures and Level of Service (LOS), to support signal optimization, with built-in archiving for historical trend analysis.
Learn moreLive travel time and speed
Gain continuous visibility into travel times and speeds across entire networks or specific corridors. Updated in real time so operations teams always have an accurate picture of current conditions.
Multi-corridor monitoring
Track travel times and speeds across multiple corridors, custom zones, or the entire road network simultaneously from a single iNode dashboard, no navigating between separate studies.
Comparative route travel times
Live side-by-side comparison of primary and alternate route travel times. Motorists and operators see exactly which route is fastest, updated continuously as conditions change.
Predictive travel time
Forward-looking travel time estimates based on current conditions and historical patterns, giving operations teams and VMS content the data to stay ahead of congestion rather than reacting after it develops.
VMS automation
Live travel times fed directly to Variable Message Signs without manual intervention. Sign content updates automatically as conditions evolve so motorists always see accurate, actionable information.
Historical archiving
All travel time data archived in iNode from the moment collection begins. Full analytics on historical data for trend analysis, before/after comparisons, and planning alongside live monitoring.
Live travel time metrics
Data delivered per route, updated continuously.
Queue & incident detection
Detect queue formation and traffic incidents automatically before they escalate. iNode identifies abnormal conditions and delivers alerts within minutes of detection, giving operations teams time to act.
Back-of-queue detection
Real-time queue monitoring
iNode detects queue formation on monitored routes, giving operations teams time to respond before spillback reaches intersections or ramp terminals.
Queue length & location
Monitor not just that a queue exists, but how far it extends and exactly where the back of queue is, updated continuously as the queue grows or clears.
Configurable thresholds
Set detection thresholds per location and time of day. Operations teams receive alerts only when conditions exceed meaningful criteria, reducing alert fatigue.
Off-ramp & interchange queue
Detect off-ramp queue formation before queues reach the mainline, critical for high-volume interchanges where spillback creates mainline hazards.
Incident detection & assessment
Automatic incident detection
iNode identifies abnormal speed and travel time patterns indicating crashes, stalls, or unexpected events. Alerts fire within minutes of detection, before calls come in from the public.
Incident impact assessment
When an incident is detected, iNode quantifies congestion impact on the affected corridor and all alternate routes simultaneously, showing how far the queue has grown and which roads are absorbing diverted traffic.
Context layers
Overlay incident feeds, camera feeds, and network conditions on the monitoring view. Operators see the cause of emerging congestion, not just its location. Toggle layers based on situational needs.
Speed event detection
Monitor operating speeds on corridor segments and detect exceedances. On work zone corridors, speed event detection is a direct worker safety input, identifying vehicles exceeding posted limits.
Intersection live data
Intersection-level monitoring brings real-time visibility to approach speeds, queue formation, and vehicle counts at the point of control, giving operations teams the data to manage signal timing and respond to localized congestion before it propagates.
Approach speed monitoring
Real-time speed on every monitored approach. Detect deceleration patterns indicating queue formation before it becomes visible in aggregate corridor travel time data.
Intersection queue detection
Continuously measure queue length at approach level. Know when approach queues exceed normal cycle lengths and require signal timing intervention before overflow occurs.
Vehicle counts & classification
Real-time vehicle counts and classification at intersection approaches. Data feeds into iNode and supports signal performance analysis and turning movement counts.
Multi-approach simultaneous view
Monitor all approaches to a monitored intersection simultaneously from a single iNode view, north, south, east, west, without switching between separate studies.
Intersection delay measurement
Measure control delay at monitored intersections in real time. Identify where delay is growing and correlate with signal timing plans, incident activity, or upstream corridor congestion.
Signal system integration
Real-time intersection data integrates with ATMS and adaptive signal control systems, providing a live performance feed for signal timing decisions and network-level optimization.
