BikeNYC数据,202101-citibike-tripdata.csv 及以前的数据字段为:'tripduration, starttime, stoptime, start station id, start station name, start station latitude, start station longitude, end station id, end station name, end station latitude, end station longitude, bikeid, usertype, birth year, gender' 一共15个,而之后的'ride_id, rideable_type, started_at, ended_at, start_station_name, start_station_id, end_station_name, end_station_id, start_lat, start_lng, end_lat, end_lng, member_casual' 只有13个,当前数据预处理脚本nycbike.py 只能处理之前的数据。对于之后的数据无法处理。
I have one question regarding the config files of PEMSD4 and PEMSD8:
Bigscity-LibCity-Datasets/pemsd4.py
Lines 94 to 95 in 1921e44
Why the "set_weight_link_or_dist" is "link" and "init_weight_inf_or_zero" is "zero"?
Should they be "dist" and "inf", just like the setting of "PEMSD7(M)"?
Another similar question on Beijing_Subway:
Bigscity-LibCity-Datasets/beijing_subway.py
Lines 280 to 281 in 1921e44
Thank you!
The gridod file is needed when running the STDN (Revisiting Spatial-Temporal Similarity: A Deep Learning Framework for Traffic Prediction), but is missing in the Google Drive.
I created it following your code "nycbike20160708.py". You can now access it via the following link:

Hi. Thanks for such a amazing repo. I intend to construct a dataset from raw data. For example, constructing grid-based demand dataset for traffic demand prediction task from NYCBike and NYCTaxi data. Unfortunately, I do not find any related script can do such construction. The most related script is nyctaxi_od.py
. It seems does not produce grid-based data?
Would you like to give me some suggestions?
point,linestring,polygon是怎么区分的?
Dear Authors,
I want to add one NN layer to DCRNN, STGCN, MTGNN before the final output. Do I just change the file in traffic_speed_predition folder?
I am just not very sure which method should I change. Do I rewrite the forward method in the class in each file?
File “/Bigscity-LibCity-master/libcity/model/traffic_speed_prediction/STMGAT.py", line 3, in
from dgl.nn.pytorch.conv import GATConv

Hi, thanks for the incredible work. It seems the expected field was missing during the transform process.
The field 'dyna_id' in the result file xx.dyna generated by foursquare.py was None.
ref. code:
Bigscity-LibCity-Datasets/foursquare.py
Line 63 in 145f662
dyna_id should be clarified in dyna['dyna_id'] = dyna.index
or other ways.
output file (sample):
dyna_id,type,time,entity_id,location
