Abstract (en)
[origin: EP0293724A1] During a respective signal pass (U) with the numbers 1, 2,... , the number (an,i) of the vehicles per time interval (i) is determined for a multiplicity of time intervals (i). From these original measured values compensated values (an,i) (intensity distribution) are determined per time interval in accordance with the following relation: an,i = an-1,i + alpha (an,i - an-1,i) where alpha = a predeterminable compensation factor (0 &Lang& alpha </= 1) which can be selected as a function of the traffic load, i.e. in a tendency- dependent manner. The chronological assignment (displacement of the intensity distribution) of the traffic-determining point (measuring point MS) to the traffic signal (stop line HL) is determined with the following modular function: F = (1 DIVIDED V. Max (0,DA - SR.6) - (SR/AN)) mod U'. Two compensation factors can also be provided, in which case with a rising tendency of the original measured values a first compensation factor ( alpha 1) with a higher value (e.g. alpha 1 = 0.25) and with a falling tendency a second compensation factor ( alpha 2) with a smaller value (e.g. alpha 2 = 0.125) than that of the first compensation factor ( alpha 1) are used for calculation. <IMAGE>
