Traffic Counts: Cordon Count, Quays Count DCC

Every November Dublin City Council (DCC) conducts traffic counts at 33 locations on entry points into the city centre around a 'cordon' formed by the Royal and Grand Canals. As the name suggests, the cordon has been chosen to ensure (as far as possible) that any person entering the City Centre from outside must pass through one of the 33 locations where the surveys are undertaken. In addition, every May there is a wider traffic count survey carried out at approximately 60 locations where in addition to the canal cordon locations, further counts are carried out at bridges along the River Liffey and points such as Parnell Street and St. Stephens Green.

These traffic counts provide a reliable measurement of the modal distribution of persons travelling into, and out of, Dublin City on a year on year comparable basis. The data collected is divided into the various transport modes allowing us to better understand the changing usage trends in cycling, pedestrian and various vehicle types.

Resources include a map with the 33 locations on the Cordon where data is annually collected. All 33 cordon points are on routes for general traffic into the City Centre, while 22 of the cordon points are on bus routes into the City. The numbers of people using Bus, Luas, DART and suburban rail services to enter the City Centre are collated from each of the various service providers and an Annual Monitoring Report is prepared by the National Transport Authority.

每年11月，都柏林市议会（Dublin City Council, DCC）都会在由皇家运河与大运河组成的‘管控环线’周边的33个市中心入口点位开展交通流量统计工作。正如其名，该管控环线的设置旨在尽可能确保所有从外部进入都柏林市中心的人员与车辆，均需途经这33个调查点位之一。此外，每年5月还会开展范围更广的交通流量调查，覆盖约60个点位：除运河管控环线上的点位外，还包括利菲河沿岸桥梁以及帕内尔街、圣斯蒂芬绿地等点位。
此类交通流量统计可在年度可比的框架下，可靠衡量往返都柏林市的人员出行方式分布情况。所采集的数据按不同交通出行方式进行分类，有助于我们更深入地掌握自行车、步行及各类机动车的使用趋势变化。
数据集附带一份标注了年度数据采集的33个管控环线点位的地图。所有33个管控环线点位均位于通往市中心的常规交通路线上，其中22个点位同时位于通往市中心的公交路线上。针对乘坐公交、Luas有轨电车、DART城郊快铁及郊区铁路进入市中心的人员数量，数据集会从各服务供应商处汇总相关数据，并由国家交通管理局（National Transport Authority）编制年度监测报告。
