Transportation Intersection Volumes 2017

Data includes: intersection volume totals, date of collection and Intersection location name. 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. The pedestrian and bicycle totals are raw volumes which were observed over either an 8 or 12 hour period. 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 volume • % Trucks represents the total percentage of truck volume in the All Motorized Vehicles AADT (24 hour volume) field • Pedestrians Not Factored represents the raw observed pedestrian volume over either an 8 or 12 hour observation • Bicycles Not Factored represents the raw observed bicycle volume over either an 8 or 12 hour observation Contact: Traffic Services本数据集包含交叉口总流量、采集日期以及交叉口地点名称。 精度说明：所有提供的机动车数据均基于8小时或12小时的标准统计周期采集所得。采集得到的原始总流量将被拓展为24小时流量，并结合渥太华的年平均日交通量（Annual Average Daily Traffic, AADT）值进行系数修正，最终得到修正后的24小时流量值。行人与自行车总流量为8小时或12小时观测周期内获取的原始观测流量。所有上报的数据点均通过自动交通记录仪采集，预期精度为95%±5%。 免责声明：渥太华市政府本着诚信原则提供本信息，但不对任何错误、不完整或误导性信息，或因不当使用该信息引发的任何责任作出担保或承担。 术语说明：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量，用于估算全年任意一日的机动车流量。 更新频率：每年更新——请注意，为适配交叉口流量统计项目的临时特性，统计点位可能会发生变动。 数据集属性： • 所有机动车AADT（24小时流量）：代表经系数修正后的机动车总流量 • 卡车占比：指所有机动车AADT（24小时流量）字段中卡车流量的总占比 • 未修正行人流量：代表8小时或12小时观测周期内的原始行人观测流量 • 未修正自行车流量：代表8小时或12小时观测周期内的原始自行车观测流量 联系方式：交通服务部门
