How to download the dataset from PeMS website?
zwd2016 opened this issue · comments
Hi, VeritasYin:
I really got impressed by this paper (STGCN-IJCAI-18). But there is no dataset in your code, and the PeMSD7 link is not very clear what data needs to be exported as a dataset. I'm hoping to get your help. Thank you very much for your help and looking forward to your reply.
Have a nice day!

Hey,
Thank you for your interest in our study. After you log into the PeMS website, please visit the link http://pems.dot.ca.gov/?dnode=Clearinghouse. Using following parameters to locate the dataset:
Type: Station 5-minute;
District: 7;
Time Period: Weekdays of May and June of 2012.
If everything is all right, please select 'D7 2012 Station 5-Minute' in the dashboard. Then you are able to find the requested data in the section of 'Available Files'.
Cheers, ht

Hi VeritasYin:
Thank you very much! But I can`t find the 'Time Period' in the http://pems.dot.ca.gov/?dnode=Clearinghouse.How to solve?

Hi,VeritasYin
Thank you very much for your answer.I would like to ask: When you calculating the weighted adjacency matrix , you based on "the distances among stations". I would like to ask you which indicator in the downloaded data is the distance between the stations. Is it "Station Length"? I also want to ask how to choose the Station ID.
Thanks a lot!
@sam101340
I think you have raised a good question. I also want to reproduce the results, the data so will be very important. Have you figured out how to construct the adjacent matrix yet?
@VeritasYin
Hi, I am interested in your study, and I think the graph convolutional network applied in the traffic prediction is an innovative idea.
Hi,
Thank you very much!

Hello! I am also interested in this work and want to reproduce it, but I can not download the datasets. Have you already downloaded the datasets? Would you mind share the datasets to me?
Thank you very much!
@sam101340 @CHELSEA234 @xumingxingsjtu
Sorry for my late reply.
As for construction of the adjacent matrix, please refer to issue #18. The PeMS dataset and weighted adjacent matrix will be ready to release by end of this week. Thank you for your understanding and patience.

Hello, I can't access the website "http://pems.dot.ca.gov/" to download the datasets, Does it can't work recently? If not, could you share the datasets for me? My email is xiepeng21@foxmail.com.
Thank you.
Hi @xiepeng21
So far, the PeMS website is accessible. You may try to visit it with the proxy tool. But sometimes it could be difficult. We will also release the PeMS dataset later this week.
Thanks, ht
Hi @VeritasYin Thank you for publishing the code for STGCN. Has there been any updates concerning the release of the PeMS dataset?
Hello! @VeritasYin I am reproducing the results of your paper, and I wander if you could share your baseline code HA, LSVR,ARIMA,FNN,FC-LSTM with me?
Hi @VeritasYin , could you please inform how did you form the vertex and weight matrix csvs from the available files ?
I can find so many files to download.
How can we know which sensors are on the same road? What is difference between freeway and road?
Hi, I am interested in your study. I wonder how to choose the Station ID. There are so many Station IDs, but how can I know where is the station xxx?
For the details of sensor stations, please refer to the metadata from PeMS website. It provides the following key values,
- ID | An integer value that uniquely indenties the Station Metadata. Use this value to 'join' other clearinghouse files that contain Station Metadata
- Freeway | Freeway Number
- Latitude | Latitude.
- Longitude | Longitude.
@VeritasYin Could you please share the sensors ids you used? We need a mapping from the adj matrix you released to the sensors ids from the website.
How can I download a road congestion dataset for 5 years from PeMS?

wow! it is concluded alone from questions and timely reply in the issue that you're a nice guy and walk everyone through the code like babysitting. I suppose I could go through the code faster than I did one.

Hi, how can I find weather and accident data on Pems website?
Hi, How can I merge the dataset with weather data? can I download a dataset that is a combination of traffic and weather data on PeMS?
could you please send the link for download the datasets, thank you
could you please send the link for download the datasets

Hello Sir My name is Mahesh Bhalavi
I m doing study on Traffic Path Recommendations System and find your work very interesting and referring your work for that.
For the same reason i want PeMSD 7 dataset and i m finding it difficult to download. I m reached till Available Files section as you mention in above message. From there i m finding difficult to procced as there are many metadata files from may 2012 to june 2012. I m eagerly awaiting for you help sir.
Thank You Sir
Hello, very interresting work , someone can share with me the dataset please i'am traying to undestand the code .
my mail: wissamsawsan1999@gmail.com
hi, this is a very interesting paper. Could someone please send the data to santiagoa.toso@gmail.com? I would like to follow the notebook and reproduce the code.
Thank you :)
I found there are so many available files in PeMS(Statio 5-min , district7).. Which one did you used in ur paper?
about the dataset :how many files need to be downloaded?the dataset is one day form,so do i need to download all?
