open traffic datasets

1. Caltrans Performance Measurement System (PeMS)
   Caltrans PeMS is a software tool designed specifically for Caltrans. It is the centralized repository for all of Caltrans’ real-time traffic data, enabling easy access to these data that might otherwise be dispersed across multiple districts and more difficult to obtain.
2. Seattle Inductive Loop Detector Dataset V.1 (2015)
   The data is collected by the inductive loop detectors deployed on freeways in Seattle area. The freeways contains I-5, I-405, I-90, and SR-520, shown in the above picture. This dataset contains spatio-temporal speed information of the freeway system. In the picture, each blue icon demonstrates loop detectors at a milepost. The speed information at a milepost is averaged from multiple loop detectors on the mainlanes in a same direction at the specific milepost. The time interal of the dataset is 5-minute.
3. OpenITS: OpenData
   OpenData模块的主要目标是建立多源异构交通大数据的数据资源描述、共享与应用规范与标准体系，并实现面向互联网的、开放的数据共享服务，为交通科学研究提供强大的数据支持和基础。
4. FHWA
   State highway agencies collect traffic volume data through both temporary traffic counting and continuous traffic counting programs and report their continuous counting data to FHWA on a monthly basis. Data listed here are reported by states following data format prescribed in FHWA's 2001 Traffic Monitoring Guide located at this page
5. MnDOT traffic data
   RTMC *.traffic Data (Archived Loop Data) Downloads Provided by Dr. Taek M. Kwon. The data in this archive are continuously collected by the Regional Trasportation Management Center (RTMC), a division of MnDOT, at a 30-second interval from over 4,500 loop detectors located around the Twin Cities Metro freeways, seven days a week and all year round.
