The Impact of Uncertainty on Pedestrians’ Decision to Start Roadway Crossing during the Clearance Phase

Table 3

Types of pedestrians’ roadway crossings and delay rate.

Crosswalk type	Pedestrian behaviour	Type of crossing	Light at the traffic lights at the moment of the crossing start and finish	Number of cases	Total cases	% of cases	Rate of pedestrian delay on the roadway during the red signal (sec/ped)
With countdown timer	Wait	Crossings in continuity	Green start-green finish	77	108	24.4	5.27 (c)
			Red start-red finish	0		0
			Red start-green finish	10		3.2
		Two-phase crossings	Red start-red finish (a)	19		6
			Red start-green finish (b)	2		0.6
	Cross	Crossings in continuity	Clearance start-clearance finish	27	207	8.6
			Clearance start-red finish	122		38.7
		Two-phase crossings	Clearance start-red finish (a)	51		16.2
			Clearance start-green finish (b)	7		2.2
Without countdown timer	Wait	Crossings in continuity	Green start-green finish	266	284	73.1	4.05 (d)
			Red start-red finish	11		3
			Red start-green finish	0		0
		Two-phase crossings	Red start-red finish (a)	4		1.1
			Red start-green finish (b)	3		0.8
	Cross	Crossings in continuity	Clearance start-clearance finish	12	80	3.3
			Clearance start-red finish	43		11.8
		Two-phase crossings	Clearance start-red finish (a)	12		3.3
			Clearance start-green finish (b)	13		3.6

a Waiting for the traffic gap at the median refuge island. b Waiting for the green light at the median refuge island. c The total pedestrian delay of violators on the roadway during the red light at crosswalks with the timer (seconds)/total number of violators at crosswalks with the timer. d The total pedestrian delay of violators on the roadway during the red light at crosswalks without the timer (seconds)/total number of violators at crosswalks without the timer.
