## 4 Results of Surveys
In addition, 4.13% of the respondents replied other, of which the use of navigation accounted for approximately 85% of these responses. The rest of the respondents use the phone to check the time or e-mail. The analysis highlighted one of the activities showed by the respondents often, namely \"changing music\" (over 48% while traveling and over 40% while waiting for a green signal). This activity raises serious concerns in today's use of a vehicle equipped with a stationary radio. It is visible how the development of streaming services (access to the selected soundtrack via the Internet from the position of a mobile device) affects the transport behavior of drivers and passengers. It can be guessed that these activities are performed by young people who interact with a newer generation telephone daily.

The aim of the research was also to obtain information from respondents on the self-assessment of their behavior and, from their perspective, its impact on road safety. Hence the questionnaire was asked how often they looked at the status of the sequence of light signals emitted by the beacon during the period of using the mobile phone (to make sure that the green signal period had not already begun). As many as 87.93% of respondents declare that they \"take their eyes off\" the screen every few seconds. A much smaller percentage of people do it every \(\sim\)10 s (7.54%). In the case of a longer range of time, 1.51% of the respondents declared this answer every 11-20 s, while at over 20 s this represented 3.02% of them. Then the question was asked whether using mobile devices while waiting for the green signal poses a threat to road traffic for the other road users. It turns out that less than half of the answers given (47.90%) show that there is no such threat. Slightly less, 43.31% say that using mobile devices while waiting for a green signal is dangerous. Almost 9% of people admitted that they cannot answer this question (by answering \"I don't know\"). The survey participants were also asked whether they had ever \"missed\" due to the use of mobile devices while waiting for a green signal. More than half of the respondents (57.17%) did not have such circumstances. In turn, nearly 40% stated that they had missed (late with the starting maneuver), but this situation is rare. Only 3.14% of people, when answering this question in the affirmative, also said that they were in such a situation often. In terms of road safety, two additional questions were also asked which are not related to the use of a mobile phone. When asked: \"how often do you observe the siren while waiting for a green signal\", most respondents said that they looked \"every now and then\" (72.50%). Out of the total share of answers provided, the second was \"I try all the time\" (18.47%). The remaining responses were a small percentage, i.e., \"when stopping, starting and leaving the intersection\" (5.11%), \"only when arriving, and then I observe the vehicles standing in front of me and then I make sure\" (2.95%) and \"only when stopping and starting\" (0.98%). The second question was the interest in traffic conditions at the intersection itself. Most respondents (64.24%) said that they pay attention to what is happening at the intersection all the time. One-third said that they are sometimes distracted by other situations. Only 4.72% focus their attention only after turning on the green signal on the signaling device to which the light signals refer. The last questionnaire was an open-ended question: \"what else do you happen to do while waiting for the green signal?\". The most common responses were talking with a passenger (almost 58%), singing or humming (almost 28%), tapping or tapping with your
