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.

From project input to delivery

A web-native process model showing how an agreed source can become a reviewable project output.

Text alternative: Project input proceeds to manual observation, structured data, quality assurance and quality control, client format preparation, and delivery.

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.

Illustrative intersection movement model
Synthetic four-arm intersection diagramA diagram of a fictional four-arm junction with North, South, East and West approaches and example left, through and right movement arrows.NORTHSOUTHWESTEAST

Approaches, arm count, lanes and movement rules are defined for the actual study; this diagram is a conceptual four-arm example only.

08:00–08:15East approachRightHeavy vehicle6
08:15–08:30South approachThroughBus4

Totals may be prepared by interval, approach, movement or approved class; the detailed record structure keeps each example observation traceable.

Synthetic lane-by-lane example

08:00–08:15North approachLane 2Commercial / OGV7
08:15–08:30East approachLane 3Heavy vehicle4

Lane configuration depends on the study; three lanes are shown only to demonstrate a configurable reporting dimension.

Illustrative traffic volume by interval

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.

Synthetic vehicle-classification example

08:00–08:15NorthboundLight vehicle52
08:00–08:15NorthboundCommercial / OGV9
08:00–08:15SouthboundHeavy vehicle5
08:15–08:30SouthboundMotorcycle11
08:15–08:30NorthboundCycle4

Class names are illustrative. The approved project specification defines the classification scheme; no single scheme is universal.

Synthetic roundabout entry/exit example

09:00–09:15Entry BExit 3Lane 2Commercial / OGV7
09:15–09:30Entry CExit 1Lane 1Bus3

Roundabout outputs use entry and exit relationships where required rather than forcing left/through/right terminology.

Synthetic parking observation example

Measures depend on the approved parking-study objective, inventory and observation method.

Synthetic queue observation example
TimeApproachLaneQueue measure
08:00North approachLane 1Illustrative measure A
08:15North approachLane 1Illustrative measure B
08:30East approachLane 2Illustrative measure C

Queue output is defined only by the agreed queue methodology and reference point.

Vulnerable road-user observations remain logically distinct from motor-vehicle classification unless the agreed output deliberately combines them.
