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• According to the statistics data found the p

edestrian 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)

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)

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

• 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.

Method

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.

Result

• There were one-third of three groups, include cas and demographic-matched control, time-matched control and using mobile phone.

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.

Result

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)

Result

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• The pedestrian used mobile phone that cr

ossing 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

• 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.
