“…The work of [16] mentioned that bike-sharing programs have significantly positive externalities, including the economy, the environment, and health-related externalities. Moreover, introducing bike-sharing systems gives an opportunity to organize public transport interchanges better [17]. Shared bicycles facilitate allow getting to stops and stations for those who do not own a private bike.…”

Inferring Long-Term Demand of Newly Established Stations for Expansion Areas in Bike Sharing System

Research on flourishing public bike-sharing systems has been widely discussed in recent years. In these studies, many existing works focus on accurately predicting individual stations in a short time. This work, therefore, aims to predict long-term bike rental/drop-off demands at given bike station locations in the expansion areas. The real-world bike stations are mainly built-in batches for expansion areas. To address the problem, we propose LDA (Long-Term Demand Advisor), a framework to estimate the long-term characteristics of newly established stations. In LDA, several engineering strategies are proposed to extract discriminative and representative features for long-term demands. Moreover, for original and newly established stations, we propose several feature extraction methods and an algorithm to model the correlations between urban dynamics and long-term demands. Our work is the first to address the long-term demand of new stations, providing the government with a tool to pre-evaluate the bike flow of new stations before deployment; this can avoid wasting resources such as personnel expense or budget. We evaluate real-world data from New York City’s bike-sharing system, and show that our LDA framework outperforms baseline approaches.

“…It comes to no surprise that human-powered transportation modes (pedestrian, bicycle) and sports utility vehicles (SUVs) are found at opposite ends of this performance evaluation. The authors note that electric scooters and light EVs count among the least fuel-consuming options for urban mobility, and can be competitive regarding this criterion with public transportation [142]. Nevertheless, any unnecessary mile driven, directly, i.e.…”

Current topics in combustion chemistry include aspects of a changing fuel spectrum with a focus on reducing emissions and increasing efficiency. This article is intended to provide an overview of selected recent work in combustion chemistry, especially addressing reaction pathways from fuel decomposition to emissions. The role of the molecular fuel structure will be emphasized for the formation of certain regulated and unregulated species from individual fuels and their mixtures, exemplarily including fuel compounds such as alkanes, alkenes, ethers, alcohols, ketones, esters, and furan derivatives. Depending on the combustion conditions, different temperature regimes are important and can lead to different reaction classes. Laboratory reactors and flames are prime sources and targets from which such detailed chemical information can be obtained and verified with a number of advanced diagnostic techniques, often supported by theoretical work and simulation with combustion models developed to transfer relevant details of chemical mechanisms into practical applications. Regarding the need for cleaner combustion processes, some related background and perspectives will be provided regarding the context for future chemistry research in combustion energy science.

“…Meanwhile, MCDA rarely considers user behaviors, which play a highly important role in defining impacts of transport solutions. In an effort to create a more comprehensive approach to evaluate different transport technologies for personal transportation, (Brunner, Hirz, Hirschberg, & Fallast, 2018) introduces an objective evaluation using Weighted Traffic Performance Indices (WTPI). The WTPI is able to combine life cycle perspectives with user-related criteria to assess various forms of transport modes.…”

The transport sector is responsible for a broad range of ecologic impacts, e.g., energy consumption, greenhouse gas emission or air pollution. It is therefore highly important to assess transport solutions in terms of their sustainability. Widely used approaches for sustainability analysis in the transport sector include life cycle assessment (LCA), economic approach, multi-criteria decision analysis (MDCA), and assessments based on indicators. In practice, these approaches consist of several methods, i.e., product-based LCA, fleet-based LCA, cost benefit analysis (CBA), cost effectiveness analysis (CEA), value measurement MDCA, ideal-solution based MDCA, outranking MDCA, and indicator-based assessment. Even though there is a larger number of assessment methods, a holistic framework for sustainability evaluation of different transport solutions is still missing. Selection of suitable assessment methods depends on a vast array of factors. This paper proposes to utilise “application levels” for the selection process. Firstly, the paper provides an analysis of the application levels of the common assessment methods and evaluation criteria within the transport sector based on a literature review. The application levels are illustrated by identifying two dimensions, namely system level and decision-making level, ranging from Low to High. Afterwards, a six-step framework for a holistic evaluation of transport alternatives is proposed. Keywords: sustainability assessment, economic approach, indicator-based assessment, life cycle assessment, multi-criteria decision analysis, sustainable transport
