TL;DR: This study proposes a three-index flow-based mixed integer formulation to solve a two-echelon location routing problem with simultaneous pickup and delivery by developing a multistart hybrid heuristic with path relinking (MHH-PR), which is composed of local search and a variable neighbourhood descent algorithm.

TL;DR: Wang et al. as discussed by the authors developed an enhanced spatial vector autoregressive (SpVAR) model to investigate relations in public transport systems in the case of sudden large passenger flow impact.

TL;DR: In this paper, a complex weighted traffic network key node identification method based on semi-local centrality is proposed, where the road grade is used as the weight, and the semi local centrality algorithm is adopted, so that the problems that the key nodes identification calculation complexity of the existing traffic network is high and the traffic network characteristics are not considered are solved.

TL;DR: In this paper, a converse traffic behavior identification method based on bicycle track data is proposed, which comprises the following steps: 1) bicycle driving track data are acquired and cleaned, wherein to-be-cleaned tracks comprise a track with a lower sampling rate and a track having an abnormal speed, and map matching is carried out: each track is projected to a corresponding road section to realize map matching.
