Traffic Speed Modeling

An apparatus comprising:

• at least one processor;
• and
• a memory coupled with the processor and including computer program code and operable to store traffic data generated by devices configured to record traffic data representing speeds of vehicles traveling a road segment;
• and
• the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
• separate the traffic data into zero speed data and non-zero speed data;
• determine a zero speed characteristic value of the zero speed data;
• determine at least one non-zero speed characteristic value of the non-zero speed data;
• and
• generate a representative traffic value for the road segment as a function of the zero speed characteristic value and the non-zero speed characteristic value.
