Travel times of certain road segments explicitly reflect the traffic conditions of those sections. Effective TTP of road segments is instrumental in route planning, traffic control, and traffic management. However, the accuracy of TTP is greatly affected by the intricate topological structure of traffic network and the dynamics of traffic flow over time. This paper develops a TTP method based on the\n            <jats:bold>spatial-feature-based hierarchical clustering (SFHC)<\/jats:bold>\n            and\n            <jats:bold>deep multi-input gated recurrent unit (DMGRU)<\/jats:bold>\n            . The proposed two-stage method is capable of capturing the spatial-temporal features of traffic network. Specifically, the SFHC divides the road segments into several clusters having similar traffic features, and then the clustered data is fed into the DMGRU for TTP. Our experiments conducted on the practical dataset demonstrate that the designed prediction method can achieve the\n            <jats:bold>mean absolute percentage error (MAPE)<\/jats:bold>\n            of 3.3109% and\n            <jats:bold>mean absolute error (MAE)<\/jats:bold>\n            of 2.5658, which outperform various combinations of baseline clustering algorithms and prediction models.\n          <\/jats:p>","DOI":"10.1145\/3544976","type":"journal-article","created":{"date-parts":[[2022,6,23]],"date-time":"2022-06-23T09:02:42Z","timestamp":1655974962000},"page":"1-21","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Travel Time Prediction Method Based on Spatial-Feature-based Hierarchical Clustering and Deep Multi-input Gated Recurrent Unit"],"prefix":"10.1145","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2149-2310","authenticated-orcid":false,"given":"Hao","family":"Fang","sequence":"first","affiliation":[{"name":"College of Computer and Data Science, Fuzhou University, Minhou County, Fuzhou City, Fujian Province, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2805-7183","authenticated-orcid":false,"given":"Yiwei","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Computer and Data Science, Fuzhou University, Minhou County, Fuzhou City, Fujian Province, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7668-7425","authenticated-orcid":false,"given":"Chi-Hua","family":"Chen","sequence":"additional","affiliation":[{"name":"College of Computer and Data Science, Fuzhou University, Minhou County, Fuzhou City, Fujian Province, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1741-5590","authenticated-orcid":false,"given":"Feng-Jang","family":"Hwang","sequence":"additional","affiliation":[{"name":"Department of Business Management, National Sun Yat-sen University, Kaohsiung, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2022,12,20]]},"reference":[{"key":"e_1_3_1_2_2","doi-asserted-by":"publisher","DOI":"10.1587\/transinf.2018EDP7299"},{"key":"e_1_3_1_3_2","doi-asserted-by":"publisher","DOI":"10.1109\/TITS.2018.2835523"},{"key":"e_1_3_1_4_2","doi-asserted-by":"publisher","DOI":"10.1109\/TITS.2021.3065404"},{"key":"e_1_3_1_5_2","doi-asserted-by":"publisher","DOI":"10.3115\/v1\/D14-1179"},{"key":"e_1_3_1_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.eswa.2018.11.028"},{"key":"e_1_3_1_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.trc.2020.102674"},{"key":"e_1_3_1_8_2","doi-asserted-by":"publisher","DOI":"10.1109\/ITSC.2016.7795686"},{"key":"e_1_3_1_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.trc.2014.02.016"},{"key":"e_1_3_1_10_2","doi-asserted-by":"publisher","DOI":"10.1145\/3357384.3357870"},{"key":"e_1_3_1_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.trb.2014.04.006"},{"key":"e_1_3_1_12_2","doi-asserted-by":"publisher","DOI":"10.1109\/ITSC.2006.1706789"},{"key":"e_1_3_1_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.trc.2020.102639"},{"key":"e_1_3_1_14_2","doi-asserted-by":"publisher","DOI":"10.1109\/TITS.2019.2963722"},{"key":"e_1_3_1_15_2","doi-asserted-by":"publisher","DOI":"10.1080\/10629360600880684"},{"key":"e_1_3_1_16_2","doi-asserted-by":"publisher","DOI":"10.1162\/neco.1997.9.8.1735"},{"key":"e_1_3_1_17_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.future.2021.07.012"},{"key":"e_1_3_1_18_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00521-021-06560-z"},{"key":"e_1_3_1_19_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.trc.2015.07.010"},{"issue":"10","key":"e_1_3_1_20_2","first-page":"1995","article-title":"Convolutional networks for images, speech, and time series","volume":"3361","author":"LeCun Yann","year":"1995","unstructured":"Yann LeCun, Yoshua Bengio, et\u00a0al. 1995.
