The electricity generation/supply and transportation sectors are the two largest contributors to greenhouse gas (GHG) emissions in U.S., vehicle-to-grid (V2G) technology is a rapidly emerging solution reduce these with adoption of battery-electric (BE) vehicles. Deployments BE transit school buses expected have larger battery capacities than passenger vehicles, making them more feasible candidates for V2G service. Five generation regions considered cash flow analysis diesel over their entire...

An unconventional left-turn treatment called contraflow lane (CLL) design has been increasingly used in China to relieve traffic congestion associated with movements at signalized intersections. This study proposed a procedure for estimating the queue length intersections CLL design. Field data were collected six approaches five city of Handan, China, and 40 h recorded. A binary logit model was developed estimate probability driver stopping presignal when there are still vacant spaces...

Abstract This study estimated the operational impacts of left-turn waiting areas at signalized intersections using VISSIM simulation technique. A procedure was proposed to model capacity single lanes with in VISSIM. Using data collected from 7 different sites, calibrated and validated. The results were compared field measured capacity, as well analytical developed our previous studies. yields a Mean Absolute Percent Error (MAPE) 8.28% for exclusive lanes, indicating that provides reasonable...

This paper aims to estimate the impacts of pedestrians on capacity and average control delay for major street through traffic at two-way stop-controlled (TWSC) intersections. A procedure was proposed expected vehicles based pedestrian arrival time motorist yielding behavior. Field data were collected calibrate crucial parameters in established models. The models then validated against field measured data. It found that calibrated provided reasonable estimates. Based models, sensitivity...

The rivalry between ridesourcing and the traditional taxi has posed great challenges to traffic management authorities. Understanding spatial patterns influencing factors of their usage can help authorities develop insightful policies strategies coordinate operations two services better. This study develops a novel geographically temporally weighted regression model (GTWR) unravel spatiotemporal based on high-resolution GPS dataset. developed GTWR achieves greater performance than other...

The power supply reliability of the urban distribution networks is being challenged by cable faults. Owing to complex factors, such as system neutral, fault condition, and DG integration, it difficult detect locate cable. In this paper, equivalent circuit model firstly created considering multi-conductor couplings. mathematical relation amplitude differences between zero-sequence currents those flowing in sheaths armors at local end healthy cables are then derived theory. Finally, according...

Summary This study aims to propose a method conduct multi‐objective analysis of traffic treatments by taking into consideration multiple external impacts. To illustrate the procedure, economic benefit converting two‐way stop‐controlled (TWSC) intersection right turn followed U‐turn (RTUT) was calculated, considering not only safety impacts but also operational and environmental First, vissim simulation models were developed obtain total travel time, vehicle emissions, fuel consumption for...

In recent years, left-turn waiting areas were increasingly used to improve traffic efficiency at signalized intersections in China. This paper evaluated the operational impacts of dual lanes intersections. An analytical model was proposed estimate capacity with areas. Based on data collected 12 sites Nanjing, cross-sectional analysis conducted compare start-up lost time and saturation headways passenger cars under four scenarios. The results indicated that outside provide slightly lower. For...

This study developed a procedure to conduct multiobjective evaluations in the traffic countermeasure (CM) selection process at two-way stop-controlled (TWSC) intersections. The economic benefits of three vehicle safety–related CMs were calculated considering not only safety impacts, but also operational and environmental impacts. First, for each CM, VISSIM simulation models obtain average delay, emissions, fuel consumption intersection before after treatment. impacts as change delay costs....

Objective: To explore and descript the association of air pollution with outpatient visits in a hospital Taiyuan during 2013 haze episode. Methods: Data were collected comprehensive Taiyuan. API was gained from website Shanxi Environmental Protection Bureau data weather China website. There two series for this study. T1 Oct.2012 to Jan.2013 T2 Oct.2011 Jan.2012. The increment calculated through comparing daily series. Generalized additive model used identified exposure-response relationship...

Objective The aim of this study was to establish the concentration–response relationships between levels SO2 and PM10 daily numbers pediatric outpatient visits estimate benefits from air quality improved. Method period 2001 2010. data visit a major hospital in XX City; local Environment Monitoring Station monitoring Central Station; Data weather provided by Meteorological Service. Concentration-response functions(CRFs) were established generalized additive modeling (GAM) with natural log...

The valuation of time is one the most important public policy issues in project cost-benefit analysis. This paper estimates value airport access and variability developing countries with a case study Nanjing, China. An international meta-analysis being used to identify factors that may affect heterogeneity travel time. Regression models are then established for prediction results provide some new insights into impacts survey region, traffic mode, trip purpose on Considering significant...
