Intersection Turning Movement Counts
Approach-by-approach turning volumes at intersections, by vehicle type and 15-minute interval, with peak-hour factors.
AI traffic data collection · Southern California
Every vehicle, counted and classified.
Intelli Route System delivers turning movements, daily volumes, 13-class axle classification, speed, pedestrian and bicycle counts, and near-miss safety analysis from a single field deployment. We count with computer vision and verify against the video before anything leaves our hands.

Services
Eight studies, one field deployment
Each study starts with a count plan: stations, periods, modes and the output format your report needs. Several studies can run from the same cameras, so every mode shares one timeline.
Average Daily Traffic
24-hour and multi-day volume counts by direction and lane, seasonally adjusted to AADT on request.
FHWA 13-Class Axle Classification
Every vehicle sorted into the 13 FHWA/AASHTO classes, from motorcycles to seven-axle multi-trailers.
Speed Radar Surveys
Spot-speed studies with 85th-percentile, pace and percent-exceeding statistics for speed-limit and calming decisions.
Pedestrian & Bicycle Studies
Crosswalk, sidewalk and bike-lane counts with direction, crossing behaviour and peak-period profiles.
Multi-Modal Studies
Vehicles, transit, pedestrians and cyclists counted together from the same video, so every mode shares one timeline.
Right-Turn-on-Red Studies
Counts of right turns made on red, with stop compliance and pedestrian conflicts, to support RTOR restriction decisions.
Near-Miss Safety Analysis
Video-based conflict detection that finds dangerous interactions before they become crashes, scored by time-to-collision.
How it works →Near-Miss Safety Analysis
Measure crash risk without waiting for crashes
Crash records take years to build up and miss most close calls. Conflict analysis measures how close road users come to colliding at a location, so a safety review can run on days of video instead of years of reports, and improvements can be evaluated before and after construction.
Illustrative conflict. Each event is logged with location, road users, speeds, TTC/PET and a video clip.
TTC
Time-to-collision
Seconds remaining before two road users would collide if both kept their current speed and path.
PET
Post-encroachment time
Gap between the first road user leaving a conflict point and the second one arriving.
| Severity | TTC | PET | Risk |
|---|---|---|---|
| High | < 1.5 s | < 1.0 s | Critical |
| Medium | 1.5–2.5 s | 1.0–2.0 s | Significant |
| Low | 2.5–3.5 s | 2.0–5.0 s | Moderate |

Used for intersection safety audits, high-risk location screening, pedestrian safety studies, and before/after evaluation of signal timing, striping and geometric changes.
Methodology
From count plan to defensible data
AI video analytics with an engineer's discipline. Questions about a count are answered by the people who processed it.
STEP 1
Scope
We confirm stations, count periods, modes, vehicle classes and the deliverable format your study or agency requires.
STEP 2
Deploy
Field crews mount cameras and radar units clear of traffic and record for the scheduled periods.
STEP 3
Count & verify
Computer vision detects, tracks and classifies every road user. Analysts check the results against the video before release.
STEP 4
Deliver
Interval data, summary reports and diagrams, with the source video available for your own review.
