Abstract
A method and system for identifying impact of a traffic incident on a road network, wherein the impact may be measured in terms of a spatial-temporal-impact region, in terms of incident duration from the time the incident is reported to the time at which the affected road network returns to recurrent flow conditions, and in terms of a cumulative time delay of all affected drivers.
Claims20
A method for identifying impact of a traffic incident on a road network, the method comprising:
- receiving traffic data from a plurality of data-capture devices;
- and
- using a processor to:
- calculate a plurality of traffic-flow velocities, each velocity of the plurality of traffic-flow velocities being associated with a data-capture time and a specific data-capture device of the plurality of data-capture devices and,
- identify data-capture devices having an associated traffic-flow velocity less than their associated recurrent traffic-flow velocity at the data-capture time.
A system for identifying impact of a traffic incident in a road network, the system comprising:
- a plurality of data-capture devices disposed along the road network, the data-capture devices configured to capture traffic data at a data-capture time;
- a processor configured to calculate a plurality of traffic-flow velocities from the traffic data, each of the traffic-flow velocities being associated with a data-capture time and one of the traffic-data capture devices;
- and
- a processor configured to identify the data-capture devices having a traffic-flow velocity less than a recurrent traffic--flow velocity at the data-capture time.
A non-transitory computer-readable medium having stored thereon instructions for identifying impact of a traffic incident in a road network which when executed by a processor causes the processor to perform a method comprising:
- receiving traffic data from a plurality of data-capture devices;
- and
- using a processor to:
- calculate a plurality of traffic-flow velocities from the traffic data., each of the traffic-flow velocities being associated with a specific data-capture device and a data-capture time;
- and
- identify data-capture devices having traffic-flow velocities less than a recurrent traffic-flow velocity associated with data-capture devices at the data-capture time.
