How the Directional Traffic Counter Works

Count each person or vehicle by the way it travels. Give each direction its own tally. Then compare the two flows for the same period.

Name the directions: Label buttons by compass direction or destination, such as Inbound and Outbound.
Tap by direction: Tap the button for the direction each vehicle, bike or person travels.
Add turning movements: Add Left, Through and Right buttons for junction counts.
Read the split: See volumes and the percent share of each direction.

Add the two direction counts to get total flow. Subtract one from the other to find the net flow.

Directional split (%) = Peak direction ÷ (Direction A + Direction B) × 100

Example: A morning count records 660 inbound and 340 outbound vehicles. Split = 660 ÷ 1,000 × 100 = 66% inbound, written as 66/34.

This table compares flow in each direction during sample time slots.

Direction A	Direction B	Two-way total	Split (A/B)	Pattern
500	500	1,000	50/50	Balanced
550	450	1,000	55/45	Near balanced
600	400	1,000	60/40	Typical peak hour
700	300	1,000	70/30	Strong commuter peak
800	200	1,000	80/20	Event arrival or exit

This tally keeps the two directions of a flow apart. You might count eastbound and westbound cars, or entries and exits.

Use a clear line or point for each count. Record each crossing once. Keep both sides on the same time window so their totals can be compared.

Use direction counts for roads, doors and paths. Here are five tasks that use the same idea.

Commuter studies: Count inbound and outbound flow at morning and evening peaks.
Junction turning counts: Count left, through and right movements on each approach.
Cycle lane planning: Count cyclists in each direction on a street.
Event traffic: Count arrivals and departures at a stadium.
One-way trials: Compare flow before and after a one-way system.
