Dynamic Combined-Mode Traffic Network Model considering Transfer Behaviors
Journal of Advanced Transportation, 2020 We propose a dynamic combined-mode traffic network model considering transfer behaviors. We assume that travelers can be classified into two classes: one class is pure-mode travelers who complete a trip by single transportation mode, and another is ...

Queueing at a Single Serving Point with Group Arrival
Journal of the Royal Statistical Society Series B: Statistical Methodology, 1960 SUMMARY Some aspects are investigated of a single-server queueing process in which customers arrive in groups, but are served individually. The input is of the “general-independent” type; service is negative exponential.

Business Strategy and the Environment, EarlyView.ABSTRACT This study demonstrates how a profitable, lean, and environmentally responsible e‐waste reverse logistics system can be designed using integrated Operations Research (OR) techniques. Addressing the growing urgency of responsible consumption (UN SDG 12) and the projected rise of the e‐waste sector to USD 137.60 billion by 2029, the research ...

Refining Lane-Based Traffic Signal Settings to Satisfy Spatial Lane Length Requirements
Journal of Advanced Transportation, 2017 In conventional lane-based signal optimization models, lane markings guiding road users in making turns are optimized with traffic signal settings in a unified framework to maximize the overall intersection capacity or minimize the total delay.

Fueling Tomorrow: Scenario Planning for the Future of Gas Stations
Business Strategy and the Environment, EarlyView.ABSTRACT Transport electrification is reshaping the service infrastructures that mediate everyday mobility, yet most electrification scenario studies remain macrolevel and offer limited insight into how incumbent forecourt (gas‐station) networks can adapt under deep uncertainty.

SIR Coverage Analysis in Multi-Cell Downlink Systems With Spatially Correlated Queues
IEEE Access, 2020 In this article, we analyze the signal-to-interference ratio (SIR) coverage probability of a multi-cell downlink system with random traffic arrivals. Based on a theoretical model, in which the base stations (BSs) and devices are deployed as independent ...

Business Strategy and the Environment, EarlyView.ABSTRACT The aim of the study is to examine the public acceptance of the deposit‐refund system (DRS), introduced in the European Union, through an extended version of the Technology Acceptance Model (TAM). The research supplemented the classic constructs of TAM (behavioral intension, perceived usefulness, and perceived ease of use) with environmental ...
