Analysis of the Dependence of Vehicle Deceleration on the Geometric Characteristics of the Road : Master's Thesis

Dosadašnja istraživanja dovela su do zaključka da se veliki broj prometnih nesreća događa na prijelazu s pravca u horizontalnu krivinu, što upućuje na to da se među uzrocima prometnih nesreća, uz pogreške samih vozača mogu razmatrati i geometrijske karakteristike ceste. S ciljem povećanja razine sigurnosti u prometu provode se nove analize i istraživanja. U radu su prikazani postojeći modeli koji su obrađivali fenomen usporenja na prijelazu s pravca u horizontalnu krivinu na temelju podataka o geometrijskim karakteristikama ceste. Obradom podataka mjerenih od strane 20 vozača na dionici Vrlika – Sinj, izrađeni su regresijski modeli intenziteta usporenja vozila, napravljena je usporedba s nekim od postojećih modela te su doneseni zaključci o utjecaju geometrijskih karakteristika ceste na intenzitet usporenja vozila.Previous research has led to the conclusion that a large number of traffic accidents occur at the transition from an approach tangent to a horizontal curve, which indicates that among the causes of traffic accidents, in addition to the mistakes of the drivers themselves, the geometric characteristics of the road can also be considered. With the aim of increasing the level of traffic safety, new analyses and research are being carried out. The paper presents some previous models that processed the phenomenon of deceleration at the transition from an approach tangent to a horizontal curve based on data on the geometric characteristics of the road. By processing the data measured by 20 drivers on the section Vrlika - Sinj, regression models of the intensity of vehicle deceleration were created, a comparison was made with some of the existing models, and conclusions were drawn about the influence of the geometric characteristics of the road on the intensity of vehicle deceleration
