The effects of mobile phone use on pedestrian crossing behaviourat signalised and unsignalised intersections

學生:董瑩蟬

purpose
Purpose
  • This paper main investigated the pedestrian crossing road behavior.
  • When the pedestrian used mobile phone that there behavior different with no used mobile phone.
  • When the pedestrian crossing at the signalised and unsignalised intersectionsthat behavior different.
reference
Reference
  • According to the statistics data found the pedestrian accident rate between 11 to 14 percentage. (NHTAS, 2006; Australian Transport safety Bureau, 2005)
  • When the vehicle speed more than 40 km/h that pedestrian has higher risk. (Ashton,1981)
  • The 15% pedestrian accident because they owe attention. (Bungum et al.,2005)
reference1
Reference
  • Many studies found that mobile phone impact attention for driver. (Caird et al.,2004; Horrey et al., 2004; Young et al.,2003)
  • The road crossing behavior demand several cognitive attention. (Tabibi et al., 2003; Whitebread et al., 1999)
reference2
Reference
  • Some studies showed that the mobile phone have negative impacts. (Gartner et al., 2002)
  • The auditory distraction may effect the driver performance. (Green et al.,1993; Jancke et al.,1994)
method
Method
  • There are 546 participant this study.
  • There were three groups on this study, there are used phone, no used phone but cross the same direction (time- matched control), no used phone but age and gender the same time-matched control (demographic-match control).
  • The recorded data described with table 1.
result
Result
  • The pedestrian distributed:
  • 270 females and 276 Males.
  • There are 48 at low socioeconomic status, 330 medium and 168 high.
  • 240 at signalised and 306 at unsignalised intersections.
  • There were 390 observed on weekday, 237 on weekend.
  • The observed 158 in the morning, 292 in the afternoon, 96 in the evening.
result1
Result
  • There were one-third of three groups, include cas and
  • demographic-matched control, time-matched control
  • and using mobile phone.
result2
Result
  • The time-matched control groups were significantly older than case and demographic-matched control.(t562=7.52,P<.001)
  • There were 182 pedestrian used mobile phone when crossing road. There were include 140 hand-held, 6 hand-free and 36 text messaging.
result4
Result
  • The females used mobile phone
  • that crossing speed slower than
  • demographic-matched control.
  • (F(1,59)=4.529, p=0.038)
  • The males talking on a phone
  • that crossing speed faster than
  • time-matched control.
  • (F(1,57)=7.991,p=0.006)
  • The males talking on a phone
  • that crossing speed not different
  • from demographic.
  • (F(1,65)=0.016, p=.899)
result6
Result
  • The female talking on a mobile
  • phone that crossing speed
  • not different from controls.
  • (F(1,138)=0.002, p=.963)
  • The males talking on a mobile
  • phone that crossing speed
  • slower than demographic-
  • match control.
  • (F(1,57)=1.121,P=.291)
discussion
Discussion
  • The pedestrian used mobile phone that crossing speed slower than no used mobile phone. It similar to Bungum et al. (2005) that found the cognitive distraction.
  • Some studies found that the driver used mobile phone the driving speed become slower. (Brown et al.,1969; Burns et al.,2002…ect.)
  • Many studies showed the used mobile phone that increased driver workload.

(Cain et al.,1999; Atchley et al.,2004…ect.)

conclusion
Conclusion
  • The pedestrian used mobile phone when they crossing road that increased cognitive distribution.
  • The pedestrian used mobile phone that may effect the road crossing safety.
