Analysis of traffic volume at the selected crossroads without traffic lights

Abstract

The study presents contains traffic volume measurements performed at the crossroads of Zwierzyniecka, Powisle and Retoryka streets in Krakow. The research was based on the observations of passing vehicles and including the vehicle kind and directional structure, in five-minute time intervals. The methodology was used in accordance with the Instruction for calculating intersection capacity without traffic lights of the General Directorate of National Roads and Motorways. The traffic volume for the whole crossroads was relatively even, with a coefficient of variation of 9.07%. The highest record traffic volume occurs between 20 and 25 minutes of measurements and amounts to 129.85 E / 5min, while the lowest is 96.2 E/ 5min, observed during the eighth measurement interval. The largest percentage in the generic structure (around 88%) are passenger cars. The share of heavy vehicles in traffic is 12.35%.
