Understanding network travel time reliability with on-demand ride service data

Xiqun (Michael) CHEN, Xiaowei CHEN, Hongyu ZHENG, Chuqiao CHEN

Frontiers of Engineering Management 2017, Volume 4, Issue 4,   Pages 388-398 doi: 10.15302/J-FEM-2017046

Abstract: Travel time reliability is of increasing importance for travelers, shippers, and transportation managersTo better evaluate the urban network-wide travel time reliability, five indices based on the emergingon-demand ride service data are proposed: network free flow time rate (NFFTR), network travel time rateThese indices take into account the probability distribution of the travel time rate (i.e., travel timeof the road network traffic dynamics and day-to-day travel time variations.

Future urban transport management

Frontiers of Engineering Management   Pages 534-539 doi: 10.1007/s42524-023-0255-3

Abstract: The incorporation of disruptive innovations into the transportation industry will inevitably cause major upheavals in the transportation sector. However, existing research lacks systematic theories and methodologies to represent the underlying characteristics of future urban transport systems. Furthermore, emerging modes in urban mobility have not been sufficiently studied. The National Natural Science Foundation of China (NSFC) officially approved the Basic Science Center project titled “Future Urban Transport Management” in 2022. The project members include leading scientists and engineers from Beijing Jiaotong University, Beihang University, and Beijing Transport Institute. Based on a wide range of previous projects by the consortium on urban mobility and sustainable cities, this project will encompass transdisciplinary and interdisciplinary research to explore critical issues affecting future urban traffic management. It aims to develop fundamental theories and methods based on social and technological developments in the near future and explores innovative solutions to implement alongside these emerging developments in urban mobility.

The Realistic Pattern and Path Choice of the Development of Agricultural Software Industry

Ma Chen, Li Jin, Zhang Qian, Feng Xian, Jie Xiaojing

Strategic Study of CAE 2021, Volume 23, Issue 4,   Pages 19-29 doi: 10.15302/J-SSCAE-2021.04.003

Abstract:

As the integration of information technology and agricultural development accelerates, the agricultural software industry has emerged to support the development of smart agriculture. In this article, we first analyze the development status of and challenges faced by China’s agricultural software industry by analyzing the development strategies of the industry in China and abroad and using literature review and survey data. Subsequently, we propose the strategic goals, major engineering projects, and policy measures for the development of China’s agricultural software industry. China’s agricultural software industry has a large gap with other countries in terms of technology development and promotion, enterprise operation, and user accumulation. The major challenges include difficulty in development, weak innovation capabilities, low return on investment, and insufficient protection of intellectual property rights, restricting the growth of China’s agricultural software industry. China should regard the software development of agricultural technologies as the main line and focus on strengthening the innovative capabilities of its agricultural software industry by 2035. The major engineering projects we proposed involve agricultural enabling software and platform development, precision agriculture management software application promotion, agricultural software industry cluster establishment, and agricultural software enterprise cultivation. Furthermore, China should improve its policy support system, strengthen the overall coordination mechanism, optimize the discipline system, and strengthen talent training for the agricultural software industry.
