Allocation strategies in a dockless bike sharing system: a community structure based approach

This study develops a methodology to determine the optimal allocation position to deploy the bikes in a competitive dockless bike sharing market. The community structure approach in complex network theory is utilized to offer the bike allocation strategies to the market leader in two specific market regimes, with a potential competitor, and without a potential competitor. Two different heuristics are proposed to handle the two scenarios respectively due to different design objectives, wherein the first one aims to attract maximum users and the other one aims to use minimum resources to cover maximum service area. Two hypothetic networks are adopted to illustrate the difference in design under these two regimes. Two numerical studies–a simplified Sioux Falls network and a real network in Singapore–are used to demonstrate the algorithm performance and show the applicability of the model for the scenario that no potential competitor exists

Electric scooter safety: An integrative review of evidence from transport and medical research domains

Safe mobility is a prerequisite in the paradigm shift toward sustainable cities and societies. Yet, the serious safety concerns associated with the practice of emerging modes such as electric scooters (e-scooters) are a major challenge for a smooth adoption of these transport modes. We have systematically reviewed peer-reviewed e-scooter safety papers with a primary focus on transport and a secondary focus on medical research domains. Our findings suggest a dire need for analysing interactions of e-scooters with other road users, and, subsequently, adopting surrogate safety measures for e-scooters. Also, it is determined that head and face injuries are the most common injury types for e-scooter riders involved in collisions. The absence of uniform regulations for the practice of e-scooters could potentially affect their safe adoption. The findings highlight the importance of providing uniform regulations for safety gears as well as the prevention of riding under the influence
