Traffic data resource
What can a traffic count deliverable look like?
This original, web-native resource explains possible TMC, classification, lane, roundabout, parking, queue, active-travel and QA/QC structures without presenting a client workbook, project record or fixed reporting template.
A web-native process model showing how an agreed source can become a reviewable project output.

Synthetic intersection data
A movement matrix starts with a defined study structure.
A junction can have three, four, five or more arms. Approaches, lanes, movements, classes and intervals are included only where the project scope calls for them.
Approaches, arm count, lanes and movement rules are defined for the actual study; this diagram is a conceptual four-arm example only.
| Time interval | Approach | Movement | Vehicle class | Count |
|---|---|---|---|---|
| 08:00–08:15 | North approach | Left | Light vehicle | 42 |
| 08:00–08:15 | North approach | Through | Commercial / OGV | 12 |
| 08:00–08:15 | East approach | Right | Heavy vehicle | 6 |
| 08:15–08:30 | South approach | Through | Bus | 4 |
Totals may be prepared by interval, approach, movement or approved class; the detailed record structure keeps each example observation traceable.
| Interval | Approach | Lane | Classification | Count |
|---|---|---|---|---|
| 08:00–08:15 | North approach | Lane 1 | Light vehicle | 31 |
| 08:00–08:15 | North approach | Lane 2 | Commercial / OGV | 7 |
| 08:15–08:30 | East approach | Lane 3 | Heavy vehicle | 4 |
Lane configuration depends on the study; three lanes are shown only to demonstrate a configurable reporting dimension.
Text equivalent: the synthetic example totals are 71, 85, 78 and 62 across four consecutive 15-minute intervals. The values are illustrative and do not describe observed traffic.
| Interval | Direction | Vehicle class | Count |
|---|---|---|---|
| 08:00–08:15 | Northbound | Light vehicle | 52 |
| 08:00–08:15 | Northbound | Commercial / OGV | 9 |
| 08:00–08:15 | Southbound | Heavy vehicle | 5 |
| 08:15–08:30 | Southbound | Motorcycle | 11 |
| 08:15–08:30 | Northbound | Cycle | 4 |
Class names are illustrative. The approved project specification defines the classification scheme; no single scheme is universal.
| Interval | Entry | Exit | Lane | Vehicle class | Count |
|---|---|---|---|---|---|
| 09:00–09:15 | Entry A | Exit 2 | Lane 1 | Light vehicle | 38 |
| 09:00–09:15 | Entry B | Exit 3 | Lane 2 | Commercial / OGV | 7 |
| 09:15–09:30 | Entry C | Exit 1 | Lane 1 | Bus | 3 |
Roundabout outputs use entry and exit relationships where required rather than forcing left/through/right terminology.
| Interval | Entries | Exits | Occupancy |
|---|---|---|---|
| 09:00 | 6 | 3 | 41 |
| 09:30 | 5 | 7 | 39 |
| 10:00 | 4 | 6 | 37 |
Measures depend on the approved parking-study objective, inventory and observation method.
| Time | Approach | Lane | Queue measure |
|---|---|---|---|
| 08:00 | North approach | Lane 1 | Illustrative measure A |
| 08:15 | North approach | Lane 1 | Illustrative measure B |
| 08:30 | East approach | Lane 2 | Illustrative measure C |
Queue output is defined only by the agreed queue methodology and reference point.
| Crossing / route | Direction | Road-user type | Interval | Count |
|---|---|---|---|---|
| Demo crossing A | Northbound | Pedestrian | 08:00–08:15 | 18 |
| Demo crossing A | Southbound | Cycle | 08:00–08:15 | 7 |
| Demo crossing B | Eastbound | Pedestrian | 08:15–08:30 | 11 |
Vulnerable road-user observations remain logically distinct from motor-vehicle classification unless the agreed output deliberately combines them.
| Review area | Illustrative review status | Scope note |
|---|---|---|
| Study completeness | Reviewed | Locations and expected study periods |
| Interval completeness | Reviewed | Expected interval sequence |
| Movement completeness | Reviewed where applicable | Approved movement set |
| Classification completeness | Reviewed where applicable | Approved class definitions |
| Consistency review | Reviewed | Unexpected zeros, duplicates or unusual patterns |
| Reconciliation | Applied where supported | Totals and structural relationships |
| Final review | Completed | Delivery structure and recorded exceptions |
This is an example review structure. The approved scope determines which checks apply to a project.
| Time | Vehicle class A | Vehicle class B | Vehicle class C | Total |
|---|---|---|---|---|
| 08:00–08:15 | 52 | 13 | 6 | 71 |
| 08:15–08:30 | 61 | 16 | 8 | 85 |
| 08:30–08:45 | 57 | 14 | 7 | 78 |
| 08:45–09:00 | 46 | 11 | 5 | 62 |
