This paper provides insights into differences in carsharing users’ attitudes, motives for joining carsharing, and transport behaviour between users with and without another car at their disposal. It builds on revealed and stated data about members of the oldest carsharing company in the Czech Republic. Carsharing adopters without a car utilise shared cars more intensively than carsharing users with a car available in their household. On the other hand, unlike the second group, they drive fewer kilometres by car in total. The car availability in households also influences the shift in car use after joining carsharing. The sale of a car thanks to adopting carsharing is a factor leading to a decrease in overall car use. Those who have a car at their disposal within their household have a lower probability of decreasing kilometres driven after joining carsharing. Households without an additional car available seem to be less car-dependent on average than those utilising carsharing as a second or third car. They tend to be more environmentally conscious and more inclined towards policies supporting alternative modes and restricting private car use, although both groups share these beliefs. The findings open a debate over whether carsharing increases the legitimacy of restrictive transport measures against private car ownership and use.

The optimization of winter maintenance operations is a multifaceted challenge, influenced especially by legal frameworks and requirements that differ among countries. As a result, algorithms for optimal road maintanace often include a number of specific constraints and therefore are not generally applicable to different environments. This paper focuses on the algorithmic techniques employed to increase efficiency and effectiveness of winter maintenance strategies, while addressing the challenges posed by legal requirements in Czechia, that include road hierarchy and maximum time limits for the service.

Following on our research project that is focused on the use value of a product and externalities arising from the application of the new tariff policy in passenger air transport, we have proceeded to study another segment within this environment. This segment is private jets companies. This paper analyses the position of private air transport with a focus on a specific business model - Business Jets. Topic that is currently widely used in corporate environments with production entities spread across Europe. The paper focuses on a comparison of private jet companies segment and scheduled air transport under the conditions where the end user is of the passenger air transport is a company or enterprise. The comparison of these two segments is a relevant way how to prove our thesis. Recently, there is a significant deterioration in quality of the air transport service. And above, as a result of the application of the new tariff policy, there is an allocation of several costs of scheduled passenger air transport operators to the end customer.

Výsledek navrhne strukturu provozních souborů dálkových linek, u nichž se předpokládá objednávka Ministerstvem dopravy, či koncesní model spravovaný MD. Každý soubor bude co nejvíce homogenní z hlediska typu a kapacity soupravy, jakož i společných stanic, kde bude umožněn přechod soupravy mezi linkami s tím, že bude zvolena vhodná stanice pro provozní ošetření, pokud možno nevyžadující prázdné jízdy. Tento soubor tak může být přímo či v rámci nabídkového řízení zadán jedinému dopravci.

As the number of elderly population grows, a special attention to mobility of this age group is required. This paper focuses on increasingly popular service of on-demand taxi transport offered by municipalities for elderly for subsidised price. We have altered a nearest neighbour algorithm for vehicle routing problem with time windows for the purpose of the problem and evaluated on the case study of a Czech city. The goal of this study was to verify if such algorithmic approach could increase utility of vehicles and efficiency of the service and could be beneficial for the customers and service providers.

This paper focuses on the continuous location-routing problem that comprises of the location of multiple depots from a given region and determining the routes of vehicles assigned to these depots. The objective of the problem is to design the delivery system of depots and routes so that the total cost is minimal. The standard location-routing problem considers a finite number of possible locations. The continuous location-routing problem allows location to infinite number of locations in a given region and makes the problem much more complex. We present a genetic algorithm that tackles both location and routing subproblems simultaneously.
