The implementation of shared parking program can effectively increase the utilization rate existing space resources. At present, has not been widely practiced in China, and prerequisite for this prospect to be implemented is whether private owner group quickly accept program. In study, considering differences economic development, urban planning, pressure cities different levels, theory planned behavior benefit-risk perception model (C-TPB-BRA) are combined as theoretical framework explore...
With the improvement of people's quality life and rapid development automobile consumer market, problem urban parking difficulties has become increasingly prominent. In addition to insufficiency number supporting spaces, backwardness traditional lot operation model led insufficient openness transparency various information, which limits ability drivers obtain space limited spaces cannot be adequately obtained. Utilization is also one reasons for increasing difficulty parking. This article...
In order to solve the problem of cross-regional customized bus (CB) route planning during COVID-19, we develop a CB method based on an improved Q-learning algorithm. First, design sub-regional approach considering commuters' time windows pick-up stops and drop-off stops. Second, for with optimal social total travel cost, improve traditional algorithm, including state-action pair, reward function update rule Q value table. Then, setup is designed path impedance constructed obtain operating...
Currently, white light-emitting diodes (WLEDs) have been widely applied in lighting, display, and medical fields. However, there still exists the problem of low color rendering index (CRI, Ra). In this work, phosphor-converted WLEDs (pc-WLEDs) with ultrahigh Ra were fabricated using Y <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> Al Ga xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> O...
Cr/Al/Ti/Au stacks with two thicknesses of Al layers were employed as reflective n-type electrodes for 274 nm AlGaN-based flip-chip deep ultraviolet light-emitting diodes (DUV LEDs). Large bulges arose in the annealed electrode 120-nm-thick layer, resulting cracks within upper rugged SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> passivation layer after burn-in test. Sn atoms from solder paste migrated along and served leakage...
In this article, we developed a color converter of phosphor-AlN-sapphire (PAS) plate to enhance the heat dissipation phosphor film in high-power white light-emitting diodes (WLEDs). The improved performance is observed by introducing AlN with high thermal conductivity (TC), which was demonstrated finite-element analysis (FEA) simulation. proposed PAS prepared printing and sintering yellow on an AlN-coated sapphire plate. It that TC increased reduction threading dislocation (TD) density film....
The shared parking scheme improves the utilization rate of existing resources and contributes to sustainable development cities, but many private spaces that are not included in have a low China. In order better promote scheme, it is necessary study intention owners share their spaces. Therefore, this paper used Unified Theory Acceptance Use Technology (UTAUT) Benefit-Risk Analysis Model (BRA) as combined theoretical framework (C-UTAUT-BRA). Hypothesis testing using Multiple Indicators...
Shared parking has become the most effective way to utilize existing resources. Little attention been focused on drivers’ intention use shared spaces in residential areas considering individual heterogeneity. To fill this gap, paper explores influencing factors and mechanism of (SPUI) further studies preferences for different types drivers. Firstly, based extended unified theory acceptance technology that includes psychological factors, personal attributes, travel characteristics, multiple...
Deep ultraviolet (DUV) LEDs have great potential in sterilization, water, air purification, and other fields. In this work, DUV LED wafers with different quantum well (QW) widths were grown by metal–organic chemical vapor deposition. It is found that the light output power (LOP) peak wavelength of all chips are not only related to QW thickness but also affected warpage. For first time, best our knowledge, a positive correlation between LOP on same wafer was observed, which very important for...
This paper proposes an optimal dynamic supply of parking permits under uncertainties in the mixed traffic environment regular vehicles (RVs) and autonomous (AVs). The from queuing delay cruising-for-parking time, respectively, are derived permit holders' unascertainable early arrival/late departure randomness vehicle speed for users. We formulate system optimum as a stochastic control problem, aiming to minimize total time lost all On this basis, we express optimality condition...
Vehicle purchase restriction policies greatly influence people’s behavior, especially their participation in the license plate lottery. This paper focuses on socioeconomic characteristics and psychological factors of citizens participating lottery, which can serve as a reference for policy makers aiming to guide rational A Multi-Index Multi-Causal model were established based social psychology, combined with Theory Planned Behavior (TPB). Perceived car necessity, perceived behavioral...
The customized bus plays an important role in catering the special needs of travel. optimization method route planning was studied considering time windows passengers. arrival at stops were converted to equivalent travel distances. Taking minimum weighted cost operator, passengers travel, and exhaust pollution, a model based on developed. ant colony algorithm designed obtain feasible solution model. Then, Q-learning action approximation optimize solution. environment mapped into...
Intercity carpooling is gradually emerging, helping alleviate intercity traffic during holidays. Promoting holidays rarely seen in the current research. In this paper, data of RP/SP survey used to analyze travel behavior carpooling. The multinomial logit model established research key factors affecting passengers' choice Results show that passengers have obvious characteristics distance, number companions and process finding vehicles. Gender monthly income significantly influence carpool A,...
