Using cell phones while driving contribute to distractions which can potentially cause minor or major road traffic injuries and also stress among other drivers. With this background, the study was done to ascertain the proportion of handheld cell phone use while driving among road users in Mysore city and also patterns of the use by the day of week, type of road, and type of vehicle.
The study was conducted in Mysore, Karnataka, India. Four stretches of roads were observed thrice daily for 1 week. The total number of vehicles passing through the stretch and the number and characteristics of drivers using hand-held cell was noted. Pearson's Chi-square test was used to ascertain the significance of the difference in proportions.
The overall proportion of cell phone users was calculated as 1.41/100 vehicles. The observed use of handheld cell phones was 1.78 times higher on nonbusy roads than busy roads ( = 25.79, < 0.0001). More than 50% of the handheld phone users were driving a two wheeler, the proportion being 50.5% in busy roads, and 67% in nonbusy roads. There was no difference in the proportion of cell phone use by time of the day or across different days of the week.
The proportion of drivers who use cell phones is found to be relatively lower, and use of cell phones was higher on nonbusy roads.
开车时使用手机会导致注意力分散，这可能会引发或大或小的道路交通伤害，还会给其他司机带来压力。基于此背景，开展了本研究，以确定迈索尔市道路使用者中开车时使用手持手机的比例，以及按星期几、道路类型和车辆类型划分的使用模式。
本研究在印度卡纳塔克邦的迈索尔市进行。每天三次观察四段道路，持续1周。记录通过该路段的车辆总数以及使用手持手机的司机数量和特征。采用Pearson卡方检验来确定比例差异的显著性。
手机使用者的总体比例经计算为每100辆车中有1.41人。观察到在非繁忙道路上使用手持手机的情况比繁忙道路高1.78倍（χ² = 25.79，P < 0.0001）。超过50%的手持手机使用者驾驶的是两轮车，在繁忙道路上这一比例为50.5%，在非繁忙道路上为67%。一天中不同时间或一周中不同日子的手机使用比例没有差异。
发现使用手机的司机比例相对较低，且在非繁忙道路上手机使用率更高。
