Road traffic injuries (RTIs) cause significant morbidity and mortality in low- and middle-income countries. Investigation of high risk areas for RTIs is needed to guide improvements. This study provides built environmental analysis of road traffic crash hotspots within Moshi, Tanzania. Spatial analysis of police data identified 36 hotspots. Qualitative comparative analysis revealed 40% of crash sites were on local roads without night lighting and increased motorcycle density. Paved narrow roads represented 26% of hotspots and 13% were unpaved roads with uneven roadsides. Roadside unevenness was more predominate in low risk [n = 19, (90.5%)] than high risk sites [n = 7 (46.7%)]. Both low [n = 6 (28.6%)] and high risk [n = 1 (6.7%)] sites had minimal signage. All sites had informal pedestrian pathways. Little variability between risk sites suggests hazardous conditions are widespread. Findings suggest improvement in municipal infrastructure, signage and enforcement is needed to reduce RTI burden.
道路交通事故（RTIs）在低收入和中等收入国家造成了严重的发病和死亡情况。需要对道路交通事故的高风险区域进行调查，以指导改进措施。本研究对坦桑尼亚莫希市内道路交通碰撞热点地区进行了建成环境分析。对警方数据的空间分析确定了36个热点地区。定性比较分析显示，40%的碰撞地点位于没有夜间照明且摩托车密度增加的地方道路上。铺砌的狭窄道路占热点地区的26%，13%是路边不平的未铺砌道路。路边不平整在低风险地点[n = 19，（90.5%）]比高风险地点[n = 7（46.7%）]更为普遍。低风险地点[n = 6（28.6%）]和高风险地点[n = 1（6.7%）]的路标都很少。所有地点都有非正式的行人通道。风险地点之间的差异很小，这表明危险状况很普遍。研究结果表明，需要改善市政基础设施、路标和执法情况，以减轻道路交通事故的负担。
