The number of vehicles on the road is growing every year and each year too many people lose their lives and health on Polish roads. The number of accidents, including at level crossings, is very high. Despite the construction of new, safer roads, the number of collisions continues to grow and about three thousand accident participants die each year. The main causes of accidents are inadequate speed to the prevailing road conditions or regulations, driving under the influence of alcohol and random events. For this reason, the article analyzes the safety at railroad crossings in Poland. In the next stage, an exemplary system improving safety at railroad crossings is presented. The new solution was analysed using a survey. The research results presented may be applicable to other countries.

The goal of this article is to assess the views of university students on their mobility in the context of the COVID-19 pandemic. To achieve this goal, a survey was conducted to analyze changes in student mobility patterns before and during the pandemic. The research was conducted in March 2021, during the pandemic, and for its purpose, information was collected on various aspects of student mobility, including the form of study, destination, mode of transportation, and shopping location. The sample group consisted of university students from different backgrounds, and various features, including age, gender, residence, and driver's license status, were considered. In addition, the study examined the impact of COVID-19 on student mobility. The study found that the pandemic has significantly affected student mobility, with a shift towards remote or hybrid learning and preference for cars, bicycles, and walking over public transportation in bigger towns while in smaller towns and rural areas, student mobility behavior has remained relatively unchanged.
