Abstract
Systems, methods, and apparatuses are described for monitoring and visualizing traffic surprises. Traffic data is received for a region of interest comprising one or more routes. A surprise factor may be calculated for one or more routes in the region of interest based on a ratio of historical traffic data and real-time traffic data. A comparison may be performed of the surprise factor to at least one threshold. A surprise traffic message may be generated based on the comparison.
Claims17
A method comprising:
- receiving traffic data for a plurality of vehicles for a region of interest comprising one or more routes, wherein the traffic data for each vehicle of the plurality of vehicles includes position data derived from a global positioning system and traffic speed data;
- calculating real-time traffic flow data from the traffic data for one or more routes in the region;
- identifying historical traffic flow data;
- calculating, by a processor, a surprise factor for the one or more routes in the region of interest based on a ratio of the historical traffic flow data and the real-time traffic flow data;
- performing, by the processor, a comparison of the surprise factor to at least one threshold;
- generating, by the processor, a surprise traffic message based on the comparison;
- and
- transmitting, by the processor, the surprise traffic message to one or more navigation devices.

An apparatus comprising:
- at least one processor;
- and
- at least one memory including computer program code for one or more programs;
- the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least perform:
- receive traffic information for a plurality of vehicles for one or more route segments wherein the traffic information includes position data derived from a global positioning system and traffic speed data;
- calculate current traffic flow conditions from the traffic information for the plurality of vehicles;
- calculate a surprise factor for one or more route segments as a function of a ratio of historical and current traffic flow conditions;
- calculate an origin and destination matrix for the one or more route segments, and a corresponding surprise factor for each of a plurality of origin destination pairs in the origin and destination matrix;
- and
- transmit, by the processor, the origin destination matrix including traffic flow conditions for the plurality of origin destination pairs that have a surprise factor that exceeds a predetermined threshold.

A non-transitory computer readable medium comprising instructions that when executed are operable to:
- calculate a plurality of routes including a plurality of route segments from a plurality of origins to a plurality of destinations;
- receive traffic data including an average traffic level and a historical average traffic level for the plurality of route segments in a designated region;
- calculate a traffic level (TLS) for each of the plurality of routes based on a surprise factor (SF) and calculated according to the following formula:
- TLSij(t)=|1−SFij(t)|;
