Abstract

The vehicle structure, designs and materials on school bus body crashworthiness as regulated by different government agencies in bus body building firms was the topic under research study. In Kenya, thousands of vehicles are involved in vehicle collisions or crashes every year resulting in fatal accidents and severe injuries to the passengers. The specific objective was the influence of vehicle inspection testson crashworthiness of school bus in Nairobi City County. This study adopted Dym’s, Suh’s Axiomatic theory. The pragmatic paradigm and explanatory research design were used. The target population was 1500 respondents from bus body building firms and government regulatory institutions. The sample size was 315 respondents. Questionnaires, interview schedules and observation were data collection instruments. Expert judgment was used to establish validity of the questionnaires. Cronbach’s Alpha Coefficient was used to determine the reliability of the research instrument.  The data collected was analyzed using descriptive and inferential analysis with the aid of SPSS V22 software. The coefficient of determination (R squared) of .206 showing that 20.6% of the variation in crashworthiness of a bus can be explained by vehicle inspection tests. There was a positive significant influence of vehicle inspection tests on crashworthiness of a bus (β=0.396 and p <0.05). The study concluded that the vehicle inspection tests had a significant influence on the crashworthiness of school bus.  The management of school bus body construction companies need to conduct all the terminal test needed before releasing the vehicle in order to enhance crashworthiness of a bus. The Transport authority should examine and check the mandatory requirements and periodically amend them in accordance with the safety, engineering and ecological standardization.
车辆检验试验对肯尼亚内罗毕县校车耐撞性的影响
对校车车身制造企业的车身结构、设计和材料对不同政府部门规定的校车车身耐撞性进行了研究。在肯尼亚,每年有成千上万的车辆发生碰撞或撞车事故,导致致命事故和乘客严重受伤。具体目的是研究车辆检验试验对内罗毕市县校车耐撞性的影响。本研究采用Dym’s, Suh’s Axiomatic理论。本文采用了语用范式和解释性研究设计。调查对象是1500名来自巴士车身制造公司和政府监管机构的受访者。样本量为315名受访者。问卷调查、访谈计划和观察是数据收集的工具。采用专家判断法确定问卷的效度。采用Cronbach’s Alpha系数来确定研究仪器的可靠性。采用SPSS V22软件对收集到的数据进行描述性和推理性分析。决定系数(R平方)为0.206,表明客车耐撞性变化的20.6%可以通过车辆检验试验来解释。车辆检验试验对客车耐撞性有显著正影响(β=0.396, p <0.05)。研究表明,车辆检验测试对校车的耐撞性有显著影响。为了提高校车的耐撞性,校车车身制造公司的管理层需要在放行车辆之前进行所有必要的终端测试。交通运输主管部门应根据安全、工程和生态标准对强制性要求进行审查和检查,并定期进行修订。
