The increasing bar link widths and red node coloring towards the top of the diagram represent increased flow. This network-wide animated view identifies congestion spots at a glance. Link bar widths and colors can be customized to represent link occupancy, inflow/outflow, density, speed, travel time and vehicle counts. Node circle sizes and colors represent movement flows and counts.
The warm colors show elevated occupancy by lane where vehicles are queueing behind unprotected left-turning movements or traffic light signals. Intersection movements are colored similarly. Animated movement plots provide a more detailed breakdown of results that pinpoint the congestion. Each lane and turning movement can be color-coded according to occupancy, flow, density, speed or count.
The dark red lane queues in this animated plot represent the position on the link of the last vehicle which experiences delay. Congestion builds as vehicles wait for a green phase, and left-turning vehicles wait for gaps in opposing traffic streams.
This comparison shows lane queue differences at a signalized intersection across a low-demand (left) and high-demand (right) scenario. Side-by-side animations address the difficulty of comparing temporal results. Scenario comparisons can be made on any Dynameq animated plot, and can be used to contrast quality of service differences due to infrastructure modifications, behavioral changes, or demand variations.
