A volume-to-capacity ratio (V/C) of 1 indicates which condition in traffic flow?

Volume-to-capacity compares how much traffic is actually passing a point to the maximum amount the road can handle under current conditions. When this ratio is 1, the observed flow equals the roadway’s capacity—the system is operating at its limit. There is little or no spare capacity, so any additional demand tends to create queues and noticeable delays, which is what we mean by congested traffic flow. If the ratio were well below 1, the road would be in free-flow or uncongested conditions because there’s ample capacity relative to the volume.
