2 + 1 Roads
 Kosňovský, Michal ; Apeltauer, Tomáš (referee) ; Kocourek,, Jiří (referee) ; Radimský, Michal (advisor)
This dissertation addresses the possibility of using the 2+1 road arrangement in the Czech Republic. Given that there is no such 2+1 segment in the Czech Republic, it was necessary to find sections with similar characteristics, evaluate and measure the rate of accidents as well as sectional velocity. The accident rate was evaluated on 72 sections and based on this research the optimal length of 2+1 arrangement road sections was determined. Digital image analysis and license plate recognition was used to evaluate the sectional velocity. Eight selected sections was subjected to the additional sectional velocity measurement, which showed improvement in passenger vehicles travel time. Traffic model microsimulations were performed after the data analysis. 2+1 arrangement roads are suitable solution for increasing travel speeds on sections where building of four-lane road is not economically viable.
