| 3 | Network level pavement evaluation with 1 mm 3D survey system显示文摘The latest iteration of Pave Vision3D Ultra can obtain true 1 mm resolution 3D data at fulllane coverage in all 3 directions at highway speed up to 60 mph.This paper introduces the Pave Vision3D Ultra technology for rapid network level pavement survey on approximately1280 center miles of Oklahoma interstate highways.With sophisticated automated distress analyzer(ADA)software interface,the collected 1 mm 3D data provide Oklahoma Department of Transportation(ODOT)with comprehensive solutions for automated evaluation of pavement surface including longitudinal profile for roughness,transverse profile for rutting,predicted hydroplaning speed for safety analysis,and cracking and various surface defects for distresses.The pruned exact linear time(PELT)method,an optimal partitioning algorithm,is implemented to identify change points and dynamically determine homogeneous segments so as to assist ODOT effectively using the available 1 mm 3D pavement surface condition data for decision-making.The application of 1 mm 3D laser imaging technology for network survey is unprecedented.This innovative technology allows highway agencies to access its options in using the 1 mm 3D system for its design and management purposes,particularly to meet the data needs for pavement management system(PMS),pavement ME design and highway performance monitoring system(HPMS). | Kelvin C.P.Wang Qiang Joshua Li Guangwei Yang You Zhan Yanjun Qiu | 2015 | Journal of Traffic and Transportation Engineering(English Edition)2015，2，6： | 2 |

| 5 | Data envelopment analysis for highway asset investment assessment显示文摘Highway agencies have been using many of the elements of asset management with the support of various decision-making tools.To determine the most effective investment strategy with scarce resources,the integration,and hence better utilization,of existing tools and practices across asset classes is generally lacking.This paper applies data envelopment analysis(DEA)to benchmark different highway investment scenarios using existing data or data readily available through existing models.Three asset types,pavements,bridges,and traffic signage,are investigated.Asset investment analysis results from the Highway Economic Requirements System State Version(HERS-ST)application,the PONTIS bridge management system software,and purpose-built traffic signage spreadsheet are obtained to capture the changes of performance measures under various budget scenarios and are further used as the inputs for the DEA process to benchmark investment scenarios for each individual asset.Subsequently,the performance measures and budget levels are assembled in the Asset Manager-NT software,whose results are input into DEA to benchmark cross-assets resource allocation scenarios.Planning for the management of highway network is addressed via case studies in a systematic manner that recognizes the tradeoffs among different funding periods and objectives such as preserving existing investments,safety,roughness and user costs.This study has established a preliminary implementable framework of highway asset management by linking DEA approach and current widely used decision-making tools for more efficient investments within and cross assets,and better understand of the tradeoffs,costs and consequences of various asset management decisions. | Joshua Qiang Li Sue McNeil | 2021 | Journal of Traffic and Transportation Engineering(English Edition)2021，8，1： | 0 |
| 6 | Testing and assessing the performance of a new warm mix asphalt with SMC显示文摘Warm mix asphalt(WMA)is a new technology which asphalt mix is produced and placed at normal temperature.It has advantages including low cost,environmentally friendly,haul-convenience,and so on.WMA has been widely tested and applied in the USA in the last decade,but it has just started in China.Recently,a new WMA using a new plasticmacromolecule-normal temperature additive,which was called'SMC'by the production company,was introduced as asphalt modifier.Based on discussing the strength forming process of this new WMA with SMC,a series of laboratory tests,including Marshall stability test(MST),boiling test(BT),modified immersion Marshall test(MIMT),freeze-thaw splitting test(FTST),rutting test(RT),low-temperature bending test(LTBT),and abrasion loss test(ALT),were conducted in this study to assess the performance of this WMA and the capability of applying it on low volume roads in China.SMC modified asphalt mixed under normal temperature is used in testing samples.It was found that this WMA product exhibited merits on its strength,which was about 6.7 k N bigger than the requirement of5.0 k N in the JTG F40-2004,on high-temperature stability,which is about 1100 times/mm greater than the requirement of 600e1000 times/mm in the JTG F40-2004,and on its storage stability.Based on these indicators,it is recommended that this product could be used for low volume low class roads construction.However,due to the relatively lower water resistance and low-temperature cracking resistance,this product is suggested to be applied first in the areas with warm weather and little rainfall.In order to improve the performance of this WMA with SMC,further research on this SMC asphalt modifier should be continued. | Changfa Ai Qiang Joshua Li Yanjun Qiu | 2015 | Journal of Traffic and Transportation Engineering(English Edition)2015，2，6： | 0 |
| 7 | Single-cell RNA-sequencing and subcellular spatial transcriptomics facilitate the translation of liver microphysiological systems for regulatory application显示文摘Reducing the use of animal models in drug development and safety assessment has long been supported by the U.S.Food and Drug Administration(FDA).The report by Royal Society for the Prevention of Cruelty to Animals indicates that in 2020,experiments involved the use of over 100 million animals,with the United States leading the list by utilizing 20 million animals.Beyond ethical considerations associated with animal testing and the costs in terms of time and money,animal models are not always effective in predicting human reactions to drug exposure.While animal testing has been the traditional method for assessing the safety and efficacy of drugs. | Dan Li Zhou Fang Qiang Shi Nicholas Zhang Binsheng Gong Weida Tong Ahmet F.Coskun Joshua Xu | 2023 | Journal of Pharmaceutical Analysis2023，13，7： | 0 |
