SimJam learning guide
Traffic signal control concepts
This compact reference keeps engineering explanations outside the active game. SimJam teaches observation, signal phasing, protected left turns, control delay, adaptive control, mixed human/automated traffic, and emergency priority.
Stage 1Observe demand
Balance north–south and east–west traffic with a two-phase signal.
Stage 2Protect left turns
Sequence dedicated left and through phases across L/T/T lanes.
Stage 3Prioritize emergencies
Manage mixed HDV/AV traffic while limiting ambulance delay.
How scoring works
Stages 1 and 2 score Smart Signal Delay − Student Delay. Stage 3 subtracts the Emergency Priority Penalty: the average ambulance delay beyond a one-second grace period. Ambulance delay is also weighted 10× inside the traffic-delay measure. Higher total scores are better.
