When the demand exceeds available capacity, queue length studies plays crucial role. Delta Software Solutions process videos and turn into accurate lane wise queue length data that helps to minimize the risk of blockage! In general we consider rolling queues (vehicles with walking speed) as well.
We offer queue length studies for priority junctions, signalized intersections, non-signalized intersections, signalized roundabouts, non-signalized roundabouts, RIROs (Right In, Right Out), links / mid-blocks / road sections.
Team DSS is familiar with snap/spot queue data, minimum queue data, maximum queue data either in 1 min or 5 min or 15 min bins.
We do offer signalized queues (Red light ON phase / Green light ON phase) with signal timestamps recorded! Again our skilled analysts can extract desired queue length data from multiple cameras without glitches! We do offer illegal queues data as well – if required!
Queue length surveys are used to measure traffic volumes, providing gratuitous of congestion and delays. They are carried out for each lane of each junction arm. The data can be provided either by number of vehicles or in vehicle lengths or class.
Queue length at junctions may be measured in vehicle numbers or in meters or yards depending on which is specified.
The number of vehicles in the queue as the red traffic signal changes to green may be recorded, or data may be collected at regular intervals such as every five minutes. Queue length surveys are often carried out in conjunction with turning count surveys.
