Recent specific research direction 1: traffic big data analysis and modeling

1. Study the temporal and spatial characteristics and evolution law of traffic process. (1) (2) road, highway, railway, air and sea transportation.

For example, with the help of vehicle trajectory data, parking data, mobile application positioning data, electronic map data, and point of interest data, this paper studies the formation, diffusion and dissipation of urban traffic congestion, and puts forward traffic control strategies and traffic management methods to alleviate traffic congestion.

2. Study the operation efficiency and travel reliability of the transportation system. (1) Multi mode (multi-mode) transportation system; (2) efficiency and reliability evaluation; (3) the goal is to improve efficiency and reliability.

For example, "Metro bus" transportation system, from the perspective of travelers, studies the methods to improve the travel efficiency of residents; from the perspective of operators, studies the recovery ability of system failure, and finds out the key factors affecting the recovery ability of the system.

Recent specific research direction 2: analysis and modeling of traffic network structure and function

1. Evaluation of actual capacity / function of time-varying transportation network. (1) The transportation capacity of the "road" network varies from time to time. (2) The structure of effective "road" network changes sometimes.

For example, time-varying aviation network constructed by flight operation data, actual capability / function evaluation.

2. The structure and functional characteristics of composite transportation network. (1) Methods to optimize the "joint" link between multiple modes of transportation. (2) Multi mode composite "travel plan" planning method.

For example, how to optimize the combination of Beijing Guangzhou travel, railway, highway, aviation and other transportation modes (accurate to the minute).
