Developing Passenger Car Equivalents for Freeways by Microsimulation
2015
Abstract In this paper a method of estimation of the passenger car equivalents for heavy vehicles on freeway is described. The variation in traffic quality was evaluated basing on a traffic demand characterized by different percentages of heavy vehicles. Aimsun micro-simulator was used to isolate traffic conditions difficult to capture on field, to replicate them to have a number of data as much as possible numerous, and to quantify the fundamental variables of traffic flow, namely the speed, flow, density, for a test freeway segment. Model calibration was accomplished by using traffic data collected at observation sections on the A22 Brenner Freeway, Italy. In order to check to what extent…
Microsimulation-based passenger car equivalents for heavy vehicles driving turbo-roundabouts
2016
Due to its geometric design, turbo-roundabouts impose greatest constraints to the vehicular trajectories; by consequence, one can expect a more unfavourable impact of heavy vehicles on the traffic conditions than on other types of roundabouts. The present paper addresses the question of how to estimate Passenger Car Equivalents (PCEs) for heavy vehicles driving turbo-roundabouts. The microsimulation approach used revealed as a useful tool for evaluating the variation of quality of traffic in presence of mixed fleets (different percentages of heavy vehicles). Based on the output of multiple runs of several scenarios simulation, capacity functions for each entry lane of the turbo-roundabout w…

Knuta Hamsuna recepcija latviešu literatūrā 20.gs.sākumā un 21.gs. sākumā
2017
Bakalaura darbā pētīta Knuta Hamsuna popularitāte 20. gadsimta sākuma latviešu literatūrā un recepcija kritikā, kā arī apskatīta autora aktualitāte 21. gadsimtā. Darba mērķis ir noskaidrot kādus poētikas veidošanas paņēmienus latviešu autori aizguvuši no Knuta Hamsuna. Ir veikts salīdzinošs pētījums, sastatot tādu latviešu autoru kā Jānis Akuraters, Gunars Janovskis un Inga Ābele darbus ar norvēģu autora daiļradi. Pētījuma rezultātā apstiprinājusies hipotēze, ka iespaids uz 20. gadsimta literatūru bijis ievērojamāks, savukārt 21. gadsimtā aktualitāte zudusi. Noskaidrots, ka latviešu rakstnieki pielietojuši Knutam Hamsunam raksturīgo tēla psiholoģijas atklāsmi, dabas tēlojuma nozīmību daiļda…
