DeepSTD: Mining Spatio-temporal Disturbances of Multiple Context Factors for Citywide Traffic Flow Prediction

This is the implementation of DeepSTD in the following paper:
Chuanpan Zheng, Xiaoliang Fan, Chengwu Wen, Longbiao Chen, Cheng Wang, and Jonathan Li. "DeepSTD: Mining Spatio-temporal Disturbances of Multiple Context Factors for Citywide Traffic Flow Prediction", published in IEEE Transactions on Intelligent Transportation Systems (T-ITS).

Data

The Chengdu dataset with 500m*500m grid size and 15-minute time interval is provided in the './data' folder.

Requirements

Python 3.7.10, tensorflow 1.14.0, numpy 1.16.4, pandas 0.24.2

Results

We provide a pre-trained model, which achieve the following performance:

Chengdu	Workday	Weekend	All days
DeepSTD	10.36	10.78	10.48
