I'm looking for a reliable source for traffic data in Beijing. In some papers that I've read, a particular dataset is mentioned. From the articles:
"The traffic network is located between the Second Ring Road and Third Ring Road in Beijing."
" 2-min travel speed data collected from three remote traffic microwave sensors located on a southbound segment of a fourth ring road in Beijing City."
" a dataset consisting of probe vehicle data collected in the urban network of Beijing, China, during one week from June 1st (Monday) to 7th (Sunday), 2015"
"north-east transportation network of Beijing"
I've searched the internet to find this dataset of vehicle speed in Beijing and found the following links in Chinese:
Unfortunately, Chinese is not my native language and I cannot explore these sites easily.
Can someone fluent in Chinese explore these sites and see if I can request traffic speed data of previous months? Can I email them and request this data?
Also, here is a contact and some emails in this link: http://www.bjjtgl.gov.cn/jgj/96629/index.html
