Contribution to the platoon distribution analysis in steady-state traffic conditions

The traffic flow analysis and the relevant vehicle distribution (“free-moving” or “platooned” vehicles) on highway facilities at uninterrupted flow has always had fundamental importance in Highway Engineering, with special reference to topics like tra c operations, car accidents, road safety and air pollution emissions. In light of this, the study suggests a calculation algorithm as a random test generator to simulate a steady state traffic flow and to provide time headways. Thanks to the outcome produced by numerical simulations, we analysed platoon distributions within tra c flows in a steady-state regime and showed the results of numerical analyses carried out by tra c random process functions. The laws to determine “time headways” were obtained by the Pearson type III generalized distribution.
