This paper addresses the problem of providing traffic data for traffic control systems especially local traffic controllers, which optimize control sequences based on traffic loads at intersections. Optimization procedures require reliable data on preceding traffic changes for calculation of control commands. 3D wavelet representation of the road image sequence is proposed for use as an equivalent of traffic stream. Coefficients of this representation map with sufficient accuracy such traffic parameters as traffic density, traffic flow intensity and derivates. The level of wavelet decomposition is determined by the size and speed of the observed objects. Computation of the wavelet transform (3D DWT) may be easily performed using logic based circuits, which is an attractive solution for incorporation into local traffic controllers.
