A method and device for the appraisal of the quality of traffic information

摘要

A process for the appraisal of the quality of traffic information, comprising the steps ofa.) Obtained or detecting unit (v_S) and determining the travel time (f_S) the distance (l_r) from the situation (v_S),b.) Determining a time loss is - (z_S) as compared to a normal reference - travel time (f_r),c..) Receiving a message (m), determination of message data, such as disturbance length (l_m), Speed (v_m) and a travel time (f_m) the distance (l_r) from the received message,d.) Determining a message - time loss (z_m) with respect to the normal reference - travel time (f_r),e.) for all route segments and all the time intervals determining a message - distance (k_m) from the message - loss of time (z_m), a situation - distance measure k_S from the - loss of time (z_S) and a difference - distance measure a = k_m – K_Sf.) Evaluating the time loss on the basis of the difference - distance measure (a) and detecting possible degree of benefit of damage and a benefit - damage - balance andg.) Determining quality measure and quality data (qs, qn).
