    160 km/h on the Highway
    (University of Zilina, 2016) Rievaj, Vladimír; Mokričková, Lenka
    The speed limit on the highways of Slovak Republic is 130 km/h. It is recently considered the increase of this speed on some sections to the 1600 km/h. However this increase brings with it a substantial negative impacts. On the basis of its evaluation appears to increase this speed to 160 km/h as inappropriate

    Benefits of Autonomously Driven Vehicles
    (University of Zilina, 2016) Rievaj, Vladimír; Mokričková, Lenka; Synák, František
    The vehicles with high grades have the embedded systems which are essential for the operation of a vehicle with higher standard of safety. This way road transport can significantly closer to the safety of rail and air transport because the error of driver is the main cause of the accident. The expected benefits of autonomous vehicles are their ability to observe small distances between the vehicles. Based on the information from stationary sources and vehicles running near adjust their route and speed of travel so as to minimize delays in congestions. This ensures greater continuity of driving, reducing consumption of vehicles and therefore the production of greenhouse gases from road transport. If the vehicles are capable of autonomous driving is achieved higher average speed and they have been removed the mandatory brakes within driving. It achieves the higher performance of individual vehicles and thus fewer number of vehicles on the roads and less traffic congestion.

    Temperature of the brakes and the Braking Force
    (University of Zilina, 2017) Rievaj, Vladimír; Mokričková, Lenka; Synák, František
    The kinetic energy of the braking vehicle is changed into heat and the resulting heat increases the temperature of each part of brakes. The changed temperature affects the coefficient of friction between the brake lining and brake drum of brake disc. Unless the brakes are actuated hydraulically there is the warning brake pads and brake fluid. Object of examination in this article is the impact of repetitive braking to change of these parameters and the impact of time to change the boiling point of the brake fluid.
