Distracted driving is a significant factor affecting road safety and it can occur as a result of using mobile phones while driving. The aim of the current research is to present the prevalence of mobile phone use by Polish car drivers, based on the roadside and online survey. The field study showed that 11.6% of 1867 drivers were using mobile phones while being in motion and 26.1% of 203 drivers when stopped in front of traffic lights. While moving, 8.9% were manipulating the device by hand and 2.6% – holding it to ear. During the stop, 14.2% of the observed motorists were manipulating it, 3.0% – holding it to the ear, and 8.9% – talking through a hands-free or headset. To determine how many people generally use mobile phones while driving (not only during momentary observation), a questionnaire was also carried out. The vast majority of 252 surveyed drivers (82.9%) admitted to using mobile phones while driving, and an equally large proportion considered this behavior as dangerous for transport safety (81.3%). Most of the motorists reported using cell phones: rarely (44.4%), both when stopped and being in motion (58.9%), in a built-up area (63.6%), holding it in hand (43.5%) and in order to chat or write messages (81.8%). The majority of drivers using cell phones while driving were male and in the 25–44 or 18–24 age group. None of the respondents caused an accident due to the use of these devices, but 1.6% were guilty of a collision caused by this reason.

Bicycle lanes are lanes marked on a road and dedicated for exclusive use for cyclists.. Because they combine bike and motor traffic they provide directness and flow. However, a shared use of streets could result in bicycle-car accidents. Following up on the good practice Western countries have in planning cycle infrastructure, Gdansk has recently introduced bike lanes on a few streets. The aim of the research was to assess the attractiveness and safety of bike lanes as a relatively new and rare solution in Gdansk. The attractiveness was assessed using the multi-criteria method. The data for the assessment came from surveys and fieldwork (inventory, observation of cyclist behaviour, traffic counts). Additionally, safety information was supplemented with police statistics on collisions and accidents. The results show that the level of bike lane usage is rather high (more than 70%). However, 80% of the respondents do not find them as attractive as separated bike paths. The advantages indicated by bike lane users included speed, surface quality, and comfort. Those who avoiding bike lanes have pointed to insufficient sense of safety. The main problems were identified such as speed and volume of motor traffic, width of bicycle lane, surface quality and parking places located next to bike lanes. The conclusions from the research are consistent with the literature. The findings could improve the attractiveness and safety of bike lanes in Gdansk if implemented by bike infrastructure planners and designers.
