This publication focuses on the development of a regional system for monitoring and evaluating public bus delays in the Ústí nad Labem Region in the Czech Republic. The case study, through a questionnaire survey, addresses the issue of the value of time loss caused by delays in regional public bus transport in the Ústí nad Labem Region from both a societal and individual passenger perspective. The survey includes, in addition to opportunity costs, the necessity to use earlier buses due to uncertainty and the potential real financial loss of passengers, for instance, due to late arrival to work and p otential employer sanctions. Routes for the questionnaire survey were selected based on an analysis of the movement of the bus fleet to represent typical situations applicable to the entire bus transport network. The result is a financial evaluation of the losses caused by bus delays in relation to the number of passengers, the purpose of their journeys, and the value of their time. The findings reveal relatively high costs of time losses, which, when applying a co st benefit approach, allow for the return on larger infrastructure investments aimed at reducing these delays. The research results will contribute to the development of issues evaluating the economic efficiency of investments in transport infrastructure.

Traffic engineers have long sought to understand what encourages drivers to drive fast and to design road infrastructure to induce drivers to behave in a desired way. But what leads drivers to select a particular speed while driving is principally a psychological question. This paper aims to expand the understanding of the factors affecting driving speed in built-up areas of towns and municipalities. We analysed nearly 700,000 vehicles-driving on roads of regional and supra-regional significance near the Bohemian Switzerland National Park-in 20 surveys at 17 locations. A broad set of infrastructure attributes was defined and measured at each site. The collected data were analysed using statistical methods to draw general conclusions about driver behaviour that can be used to improve traffic engineering. Several of the presumed attributes were confirmed to influence driver speed choice, and several new factors were discovered and proposed for implementation in traffic engineering and mathematical modelling tools.

The substitution of fossil fuels in road transport is one of the dominant themes at this time. For a long time, compressed natural gas has been used mainly in bus transport. The test process is primarily focused on electromobility or hydrogen drive. Another option is the use of liquefied natural gas (LNG). Advantage of LNG is (compared to CNG) longer driving distance. Therefore, the article focuses on the possibilities of using LNG in freight road transport, the technological issues of propulsion and, especially, the economic cost model compared to conventional fuels.
