Transportation Midblock Volume 2023

Accuracy: All motorized vehicle data provided is based on either an 8 or 12 hour standard count. The collected raw total is then expanded to a 24 hour volume and factored by Ottawa’s Annual Average Daily Traffic (AADT) values providing a factored 24 hour value. All data points reported were collected using an automatic traffic recorder with an expected 95% +/- 5% accuracy. The City of Ottawa provides this information in good faith but provides no warranty, nor accepts any liability arising from any incorrect, incomplete or misleading information or its improper use. Annual Average Daily Traffic (AADT) is the average number of motorized vehicles in 24 hours, and provides an estimation of the motorized vehicle volume on any day of the year. Update Frequency: Annually – note locations subject to change to reflect ad-hoc nature of intersection volume count program Attributes: All Motorized Vehicles AADT (24 hour volume) represents total factored motorized vehicles midblock volume Location X, Y Contact: Transportation Data Collection & Analytics准确率：本数据集提供的所有机动车数据均基于8小时或12小时标准时长的交通计数。先将采集得到的原始总流量拓展为24小时流量，再结合渥太华市的年平均日交通量（Annual Average Daily Traffic, AADT）系数进行折算，最终得到折算后的24小时流量值。所有上报的数据点均通过自动交通记录仪采集，预期准确率为95%±5%。 渥太华市善意提供本信息，但不提供任何担保，亦不对因任何错误、不完整或误导性信息，或不当使用该信息所引发的任何责任承担赔偿义务。 年平均日交通量（Annual Average Daily Traffic, AADT）指24小时内的机动车平均通行数量，用于估算全年任意一日的机动车通行流量。 更新频率：每年一次——请注意，为适配交叉口流量计数项目的临时特性，监测点位可能会发生调整。 属性说明： 1. 所有机动车年平均日交通量（24小时流量）：代表经折算后的街区中段机动车总流量 2. 位置X、Y 联系方式：交通数据采集与分析团队
