Spatio-Temporal Redistribution of Traffic Flows during Sequential Blocking of Channels at a Signalized Intersection: A Probabilistic Approach (Case Study of Augustusplatz, Leipzig)

Summary/Abstract: The spatiotemporal redistribution of traffic flows under alternating blocking of channels at a signalized four-leg intersection is investigated using the case of Augustusplatz in Leipzig, Germany. Observations were conducted over three days, with flows recorded in 48 half-hour intervals per day across four directions and four categories of vehicles. For stochastic modelling, the negative binomial distribution, Taylor’s dispersion index (VMR), Shannon entropy, and an approximation based on M/G/1 queueing theory were applied. A mathematically grounded framework for the real-time network control is proposed, highlighting the necessity of adaptive signal timing adjustments to accommodate stochastic fluctuations and spatial overcompensation effects during node closures.
