An environmental psychologist conducted an observational study to investigate pedestrian compliance at a newly installed smart-crossing in a busy urban centre. Over a four-hour observation window, they recorded the behavioural responses of individuals arriving at the crossing while the pedestrian signal was red.
Table 1: Observed pedestrian behaviours at a red crossing signal
| Stops and waits for green signal | Crosses before signal turns green | Hesitates and steps back onto pavement | Runs across just as signal changes | Total |
|---|---|---|---|---|
| 140 | 42 | 28 | 14 | 224 |
What is the simplified ratio of the number of times pedestrians stopped and waited for the green signal to the number of times they hesitated and stepped back onto the pavement? Show your working.
