In recent years,many departments of transportation in the US have invested more resources to enhance pedestrian safety.However,there is still a need to effectively and systematically address pedestrian safety issues in low-income areas.Statistics show that pedestrians are fatally injured at disproportionately higher rates in the nation’s poorer neighborhoods.Low-income areas often are sectioned by high-volume/high-speed arterials,which compound the problem.In this study,pedestrian-vehicle crash data in lowincome areas were analyzed from two aspects:how demographic factors,road environment,and land use types influence pedestrian crash occurrence (based on frequency data)and how demographic and other factors influence severity in a pedestrian crash (based on severity data).The crash frequency modeling results show that major influential variables for higher pedestrian crash frequency include four demographic factors (proportions of older adults,commuters using public transit or biking,people with low education level,and zero-car ownership),three road environmental factors (densities of traffic signals and bus stops and proportion of higher-speed roads),and three land use factors (densities of discount stores,convenience stores,and fast-food restaurants).The injury severity modeling results show that a dark-not lighted condition is the most influential variable for severe injury pedestrian crashes,and the number of impaired pedestrians and aggressive drivers also greatly increases the probability of severe injury.Based on the analysis results,this paper makes specific recommendations for both engineering countermeasures and pedestrian safety education/outreach plans that resonate with a given area’s demographics to effectivelv improve pedestrian safety in low-income areas.

【摘要】现行的高中物理课程授课方式已经不能满足学生学习生活和发展的需要,现代高中物理教学甚至在学生的实验教学上也做出一系列要求,充分发挥学生的主观能动性和主体地位的作用,让学生自己试验探究,动手来得出实验结果,帮助学生理解和加深所学习知识内容的记忆、深化过程,充分体验试验探究过程中的乐趣。本文着眼于高中物理实验教学的一些观点及思考,谈及笔者根据个人教学实践经验的一些意见和建议,希望借阅者能够积极提
