Calculate traffic density and Level of Service (LOS).
Calculate vehicles per km/mile and per lane.
Estimate traffic conditions (LOS A-F) based on density.
Analyze road capacity and performance.
The Traffic Density Calculator helps traffic engineers, planners, and students analyze the performance of road segments. By inputting the road length, number of vehicles, and number of lanes, the tool calculates the traffic density and estimates the Level of Service (LOS) according to standard traffic engineering principles. This helps in understanding congestion levels and road capacity utilization.
Input the length of the road segment in kilometers or miles.
Input the number of vehicles observed on the segment.
Choose the number of lanes for the road segment.
See the calculated density and the estimated Level of Service (LOS).
Traffic flows freely or stably. Drivers have freedom to select their speed and maneuver. High comfort level.
Flow becomes unstable. Freedom to maneuver is noticeably restricted. Small incidents can cause significant delays.
Breakdown flow. Traffic demand exceeds capacity. Stop-and-go waves, long queues, and extreme delays.
