A1 (Croatia) - Traffic Volume

Traffic Volume

Traffic is regularly counted by means of traffic census at toll stations and reported by Autocesta Rijeka–Zagreb and Hrvatske autoceste—the operators of the northern and the southern portions of the motorway respectively. The reported traffic volume gradually decreases as the motorway chainage increases and as it passes by various major destinations and the interchanges that serve them. Thus the greatest volume of traffic is registered between Jastrebarsko and Lučko interchanges – with 31,432 vehicle annual average daily traffic (AADT), and 53,216 vehicle average summer daily traffic (ASDT) figures as that is the section closest to Zagreb. South of the Bosiljevo 2 interchange the first major drop of traffic volume is recorded on the A1 motorway, due to traffic transferring to the A6 motorway towards Rijeka. Other similar changes of the traffic volume are registered near Zadar (served by Zadar 1 and Zadar 2 interchanges) and Split served by Dugopolje interchange. Substantial variations observed between AADT and ASDT are normally attributed to the fact that the motorway carries significant tourist traffic. The seasonal increase traffic volume variations ranges 69% on the busiest, Lučko–Jastrebarsko section to 160% as measured on Sveti Rok–Maslenica section. The summer season traffic volume increase on the motorway is 120%.

Famous quotes containing the words traffic and/or volume:

    “If you don’t have a policeman to stop traffic and let you walk across the street like you are somebody, how are you going to know you are somebody?”
    —John C. White (b. 1924)

    “Measured by any standard known to science—by horse-power, calories, volts, mass in any shape,—the tension and vibration and volume and so-called progression of society were full a thousand times greater in 1900 than in 1800;Mthe force had doubled ten times over, and the speed, when measured by electrical standards as in telegraphy, approached infinity, and had annihilated both space and time. No law of material movement applied to it.”
    —Henry Brooks Adams (1838–1918)
