Session Overview
Started
Ended
Duration — first car → last car
Time between the first egress event and the last recorded turn. Represents the active observation window — not the total session clock time.
Car Counts
Total
Total egress events recorded this session.
↰ Left
Cars that turned left onto the road.
↱ Right
Cars that turned right onto the road.
Indicator Compliance
🚫 No Indicator
Cars that exited without indicating.
Non-compliance rate
No-indicator cars as a % of total egress events.
Cars per Minute
Time since first car. Stacked: total + no indicator. Line: 5-min centred average.
Peak 1-min window
Minute with highest 5-min centred moving average.
Peak volume
Raw cars in that minute and its MA value.
Director Efficiency
Avg Wait Time per Car
Average time between an egress event and the next turn event. This is the time each car spent waiting for your direction. Lower = faster release = more efficient directing. Aim for consistency, not just speed.
Cars Processed per Minute
Total turns recorded ÷ total session duration in minutes. Measures your volume throughput — how many vehicles you cleared per minute. High throughput with low wait time = optimal performance.
Car Arrival Rate
Mean Time Between Arrivals — Overall
Average time between consecutive egress events across the whole session. Shorter gaps = higher queue pressure on you. Use this to gauge how demanding the session was relative to others.
Mean Time Between Arrivals — 5-min windows
The same inter-arrival metric broken into 5-minute windows. Shows whether traffic arrived in steady bursts or peaked at specific times — useful for identifying the busiest periods and planning future staffing or signal timing.
Traffic Blockers
Total Blockers
Non-participating vehicles recorded as obstructing flow. A high blocker count relative to total cars may indicate external congestion beyond your control as director — useful context when evaluating wait times.
