The timing, effectiveness, and stringency of policy implementation are crucial for the success of COVID-19 control efforts in different countries. Index-based mobility data usually employs advanced algorithms in the processing of data optimization to ensure data quality and reliability. For example, Zhang et al. For more info and to customize your settings, hit By investigating recent COVID-19 studies from a data-oriented view, our review contributes a comprehensive summary of human mobility open data condensed into data sources, index measures, characteristics, applications, challenges, and future research directions. The POI access in SafeGraph data is categorized by industry and business (e.g. Email; . Compared with already summarized activity metrics at specific geographical scales (Section 3.2) and aggregated, constructed mobility index (Section 3.3), the raw social media records retrieved online are characterized by their aggregation-flexibility and scale-free nature. A few examples of such challenges include automated vehicle driving, environmental protection, improving human health and well-being, and improving education. Some data providers require users to submit an application indicating the purpose of data usage if users want to access the whole dataset. View daily, weekly or monthly format back to when Baidu, Inc. stock was issued. 2018). Data providers made such mobility data publicly available to facilitate COVID-19 research studies. 2014; Lee et al. Customize Settings. Exploring and examining the changing trends and patterns of human mobility in both spatial and temporal dimensions are the fundamental analyses in providing an overall picture of mobility changes across space and time. 2020), Descartes Lab Mobility Index (Warren and Skillman 2020), and indices from SafeGraph (Huang et al. For public transit data, air flight datasets have been utilized to estimate inter-country mobility, which has been one of the key drivers in disease transmission, especially at the early stages of the COVID-19 pandemic (Bogoch et al. Mobility data used in such analyses are subject to different geographic contexts and spatial scales. Kang et al. The early implementation of social and mobility restrictions is especially effective in lowering the peak value of new infections and reducing the infection scale (Kaur et al. Baidu believes they have made mobile search much easier-to-use through technologies and new functions like voice search. Apple data cover 63 countries with a timeline starting from 13 January 2020 (except for 1112 May 2020), and Google data cover 131 countries with varying timelines based on the country. Metro data have been used to estimate mobility and examine the relationship between human mobility and ridership. The online tool helps extract and query, download mobility data, and visualize the population flows interactively. Mobility pattern changes in the U.S. have been analyzed using different types of index-based mobility data, including Cuebiq Mobility Index (Fraiberger et al. Governments, professional associations and organizations, data providers, and researchers have made joint efforts to improve the stringency and implementation of regulations in addition to ensuring the ethics clearance in the process of data sharing and manipulation. In contrast to Google and Foursquare data categorized by POI access, Apple Mobility Trends Report provides transport-based metrics that are generated by counting users requests for directions in the Apple Maps app based on three types of transport modes (public transit, driving, and walking) compared to a pre-pandemic baseline value of mobility on 13 January 2020 (Apple Inc. 2020). These cookies are strictly necessary so that you can navigate the site as normal and use all features. 2020a). Founded in 2000, Baidu's mission is to make the complicated world simpler through technology. 2- Baidu Research: Baidu collaborates with top Chinese universities including Tsinghua, exploring a variety of different areas of AI . Non-commercial research efforts. Surveys are typical sources of human mobility data. One of the mobility datasets most commonly used is Google Mobility Reports that provides the percentage change of place visit frequencies in six types of locations (workplaces, residential, parks, grocery and pharmacy, retail and recreation, and transit stations) compared to a pre-pandemic baseline value of mobility from 3 January to 6 February 2020 (Google LLC 2020). However, it only estimates OD flows of the transits, presenting a very small group of population. This section describes some typical mobility datasets within each category and the methods used to generate such mobility datasets. Cash and short-term investments for Baidu Core, as of March 31, 2022, was . The research arm takes a deeper look at its associated technologies. At the city level, there are more diverse travel options by which people may choose to travel from one place to the next, including metro and bus. We work extensively on predictive analytics, aiming to generate actionable and testable hypotheses based on large amounts of data and previous experiences. China Mobile is providing Baidu with 1,388 high . The smart-card-based public transit data usually contain a certain amount of missing data due to human errors made by smart card users (e.g. (2020a) developed a geospatial web portal, named Origin-Destination-Time (ODT) Flow Explorer, by extracting and aggregating the U.S. population flows from SafeGraph mobility data. Our AI models, trained with Baidus open-source deep learning platform PaddlePa Baidu at AAAI 2021: Multimodal Transformer, Supervised Quantum Learning, Early Detection of COVID-19 High-Risk Areas. Most scheduled timetable data are publicly available on the website of transport authorities, governments, or private transport companies. 2018). The project has received support from many other research institutions and companies on data, methodology, technology, and cloud platform. Kaiwu 2.0, an upgraded version of Baidu's industrial internet platform based on Baidu AI Cloud, was officially released at Baidu World 2022, representing a further step forward in bringing AI applicationto more industries. In contrast, the data with the actual trajectories of travelers pose greater risks to individual privacy. Other types of index-based data and social media-derived mobility data have been relatively less prevalent in modeling work, possibly due to the difficulties in data retrieval and processing (Li et al. (2020); Ahangari et al. Mobility data have been integrated with epidemiological models or spatiotemporal models (e.g. Baidu CTO Haifeng Wang describes AI as a "key driving force of innovation and development," thanks to rapidly evolving core technologies, cross-domain connectivity, and expanding applications. This value gives a seven day rolling (mean) average to avoid it being distorted by weekends and bank holidays. There are many ways to aggregate the data at multiple spatiotemporal scales based on the flights origins and destinations. While it can help reveal the underlying patterns of human movement behaviors, it also poses a challenge to privacy protection as human movements are highly unique and predictable (Song et al. Many studies have applied mobility data to explore spatiotemporal trends over time, investigate associations with other variables, and predict or simulate the spread of COVID-19. Baidu Research also thinks AI is going to take hold in outer space, with sensor-loaded decision-making autonomous spacecraft roaming around extra-terrestrial planets carrying robotic arms, not only conducting scientific studies, but also mining moons and planets for resources, empowered by lessons learned in construction machinery automation to excavate continuously 24 hours a day. Keynotes, panels, and working sessions are part of the program for our international attendees. How researchers can integrate different data sources to enhance human mobility applications in the COVID-19 pandemic and any future pandemics is a critical topic. In the last quarter of 2021, the Chinese search engine giant recorded around 218 million daily active users of its app.. Other mobility data sources, such as geotagged social media data and cell phone data, may overcome such limitations by capturing individual human movements in much finer spatiotemporal resolutions. Train and bus data are usually available at the state or city level, whereas metro/subway data may be available at more locally precise scales (e.g. from 8 AM - 9 PM ET. Unacast Social Distancing Index is calculated as the percent change of mobility in average distances traveled, the percent change in non-essential visitation, and the decrease in human encounters compared to the national baseline (Unacast 2020). DAMO is its research arm. For example, mobility data retrieved from public transit systems are mode-specific and lack the holistic views of overall human spatial interactions. With tens of thousands of Apollo RT6 models to be deployed at scale, Baidu is ready to tap into a key high potential market with increasing demand, bringing the world closer to a future of driverless shared mobility. 2014). Such a high spatiotemporal resolution in a human mobility flow dataset may help monitor epidemic spreading dynamics, inform public health policy, and deepen our understanding of the change of human movement behavior within the current public health crisis. Alibaba's space predictions of the future were less imaginative, focusing on the very real demand for increased satellite connectivity and how they can improve through increased interconnectivity. The dataset is published in GitHub and is free to use. 2020). For example, the Google mobility trends report provides data on mobility to parks, workplaces, and pharmacies, while the Apple mobility trends report reflects the mobility changes of walking, driving, biking, and public transit usage, all of which cannot be revealed by other types of mobility data. education or policy-making) through careful approval and confidential agreement. Finally, Twitter data have been more commonly used in emotional analyses based on the text and keywords from the content of tweets but relatively less used to examine the relationship between human mobility and COVID-19 transmission (Porcher and Renault 2020; Xu et al. Really, they do everything. Human mobility is characterized by its multi-faceted nature, which has been evidenced by many studies (Gonzalez, Hidalgo, and Barabasi 2008; Cui, Xie, and Liu 2018). It is crucial to building a standardized framework to help researchers avoid the time-consuming and costly process of data integration and provide timely and high-quality data support for the COVID-19 studies. 3:17-cv-03301-EMC. China, US, and European countries by Djurovi 2020; Jiang and Luo 2020; Kraemer et al. The "Polaris Program" of Baidu Research provides the most advanced and cutting-e Baidu Research Bolsters Capabilities with New Labs and World-renowned Appointment to Advisory Board. However, the historical travel data for these public transit modes are typically not provided. Twitter has become the largest source of social media research data due to its policy of free access to about 1% of its total content (Martn et al. Oh yeah, and these spacebots are self-repairing as they build space laboratories and analyse big data. the cancelation of public transit). To the best of our knowledge, there is no current review summarizing the human mobility data usage in recent COVID-19 studies. 2020; Ni and Weng 2009; Belik, Geisel, and Brockmann 2011; Meloni et al. Finally, social activity data are appropriate for studies on the different types of human mobility to various places and by various trip modes. This webinar will give an introduction to this Weibo mobility index, including data sources, methodology, comparative . 2020). Since the start of the COVID-19 pandemic, human movement behaviors have been completely disrupted, and these movement behaviors show very different patterns than ones before the pandemic. 2020; Dickson et al. Baidu Mobility Data website Harvard Dataverse: COVID-19 Data Collection: Intra-city movement index: Daily data from Feb. to Mar. Mobility data refers to collected data of activities, events, and transactions through devices or services that track real-time mobility. The report-based mobility datasets from Google, Apple, Foursquare, and Facebook are highly processed with population movement information aggregated to a specific spatiotemporal scale (mostly showing the daily movement at the county or equivalent levels). To balance the needs of data sharing and privacy protection, researchers may process the data in a way that is suitable for multiple levels of access. Behind this ability to produce AI generated content (AIGC) is Baidu's ERNIE large-scale AI models for knowledge enhancement, developed based onBaidu's deep learning platform PaddlePaddle. Researchers have aggregated the data to estimate the changes in air flight activities due to demand decline and travel restrictions (Iacus et al. Such aggregated data indicate the overall patterns or changes of human mobility in a particular spatial unit with less concern about identifiable user-based information. Therefore, it is crucial to establish standards in the deposit, storage, processing, and distribution of mobility data. 2020). Second, the relationship between human mobility and the virus spread is temporal and spatial heterogeneity. Within public transit datasets, the scheduled timetable data often face fewer concerns about privacy issues. The risk is even higher when different mobility datasets are merged, even with every dataset being anonymized (Kondor et al. Foursquare Mobility Reports cover only the U.S. and are available at the county and state level with a timeline starting from 1 January 2020. To promote the value of data, Li et al. 2020). In the case study of New York City (NYC), researchers used the transit network & schedule from General Transit Feed Specification (GFTS) data, NYC Bridge Traffic Volumes data, and MTA Subway Turnstile Data (Gao et al. For studies in the U.S., Cuebiq Mobility Index has been used to predict the COVID-19 trends in Boston (Aleta et al. Baidu's joint announcement with China Aerospace of the world's first large-scale model in the field of aerospace was another highlight of Baidu World 2022. Data-driven decision making and automation are being utilized to solve significant challenges faced by our society at unprecedented scale. Cash and short-term investments for Baidu Core, as of March 31, 2022, was RMB 185.8 billion, or $29.3 billion. Refined Products. For instance, AI processors with higher computing power and lower energy consumption will continue to be invented, but also AI technology can be applied to tasks like improving energy efficiency ratios. For FY 2022, the expectation is for the search giant to generate revenues of $21.93B, which implies an annual year over year revenue growth rate of 13%. 2020; Huang et al. The painting was divided up into two pieces which have been stored at different museums. 2015; Martn et al. Chinese, Italian, Korean food) (SafeGraph 2020). 2020; Haider et al. Additionally, the monitored ADS-B-equipped aircraft data are mostly concentrated only in North America and Europe (Iacus et al. Therefore, it is of vital importance to build a new model that could integrate human mobility and socioeconomic data across regions to re-evaluate the association between human movement behaviors and socioeconomic characteristics of the underlying population during the COVID-19 pandemic and any other disease outbreaks. purposes of travels, detailed location of destinations, demographic profiles, socioeconomic status, etc.) Mobility data is of great importance as it unlocks the maximum value that can help cities become smarter and provide better transport facilities to its citizens. Already becoming widely implemented, Baidu Research thinks the technology should continue to improve by increasing qubits in scale and reducing or adapting to noise. This summary of evidence aims to help researchers familiarize themselves with these mobility datasets and select the appropriate data for their studies. The estimated number of employees at Baidu, as of June 30, 2014 was 40,500 The estimated number of Baidu users is the world 531 million Market Share Of Chinese Search Engine By Revenue The number of active monthly mobile Baidu search users is 500 million The number of mobile daily active users of the Baidu App is 70 million Baidu's digital human ambassador, Xijiajia also made an appearance to highlight the artistic potential of Baidu's technology, painting a stunningly detailed image of a cat in real time after receiving a simple command. 2020; Aleta et al. , The Register Biting the hand that feeds IT, Copyright. 2020b; Fan et al. 2020; Chen et al. In contrast, Baidu Mobility Index offers inter-city and inter-provinces population flows index with comprehensive big data sources. At the individual level, mobile phone positioning data or social media big data can be used to track individuals trajectories, daily activities, exercise routines, and travel behaviors. 3099067 2020a; Yabe et al. Most of the public transportation data from these transportation systems are provided by data service companies, but there is no standard data format. Some agencies, such as the Metropolitan Transportation Authority in the U.S., release daily turnstile data and aggregated ridership data (http://web.mta.info/developers/turnstile.html), both of which can be used to estimate travel volume. 2013; Xu et al. MOBILITY DATA: Chinese mobility continues to rise despite fresh Covid outbreak. a susceptible-infected-recovered (SIR) model or SIR-derived models), and these data have been controlled as parameters to simulate the COVID-19 cases based on different policy scenarios and to predict future trends of virus spread based on policy implications. "Baidu", "Baidu" and related graphics are registered trademarks of Baidu. 14 Sep 2021. . About Baidu Baidu, Inc. is the leading Chinese language Internet search provider. (2020a) conceptualized a mobility-based responsive index by integrating single-day distance and cross-day distance derived from massive Twitter posts worldwide, aiming to understand the dynamics of human mobility under implemented policies during the COVID-19 pandemic. To help researchers and governments worldwide with the response to COVID-19, technology companies and research institutions have made human mobility datasets publicly available after pandemic. Now that we've ushered in 2022 and closed the chapter on 2021, I look back highly impressed with the resilience of the automotive, mobility, and transportation industries. In the US, researchers estimated and shared the estimated daily dynamic OD population flows from SafeGraph at three geographic scales: census tract, county, and state (Kang et al. 454 of these are in the google play store, but, since the official marketplace is not available in china, As a result, transport authorities and governments have put increasing efforts into privacy protection; the largely anonymous individual-level transit data is only issued to organizations or institutes for specific purposes (e.g. Similarly, Huang, Wang, and Li (2018) combined mobility records from urban transportation and mobile phone signals to achieve comprehensiveness via a high data penetration ratio. However, it is only available in China. The Change in Movement metric looks at how many people are moving around and compares this number to a baseline period that predates most social distancing measures. . 2020). Although DAMO's list features AI, it does so with less focus than Baidu Research, resulting in both overlapping predictions and completely different takes. The availability column shows how users can access each data set: private, public, or application submission. Similarly, Cuebiq Mobility Index, Unacast Social Distancing, UMMI, and CSSDR can be freely accessed through browsing the dashboards in their official websites. (Foursquare Labs Inc. 2020). At the global level, air travel is the primary choice of public transit, and air flight data serve as the indicator of the mobility flow across countries and regions (e.g. Register to receive personalised research and resources by email. 2016). With the increasing availability of and soaring demands for fine-scale human mobility data, more studies are needed to develop novel parallel and scalable computing algorithms and data models to manage, process, and analyze big mobility data in a high-performance computing environment. In Q2, Baidu AI car increased by 31%, 31% year over year to RMB . Mobility-enabled devices include smartphones, shared mobility vehicles like shared bikes, scooters, and . Li et al. 2021 was a stellar year at CITYDATA. Policy measures need to be adjusted across the different phases of the pandemic. To achieve the three objectives, we searched related literature by querying mobility dataset names in Google Scholar, including peer-reviewed journal articles, high-quality preprints, and working papers. Smartphone users can now interact with DuXiaoxiao via the Baidu App, the first step towards a future when personalized digital human service becomes commonplace.

BMI is measured through gathering travel data based on more than 120 billion daily location requests from the Baidu Map app and other mobile phone apps that use Baidu's location services. For example, data used for individuals trajectories and identifications in COVID-19 related studies, such as contact-tracing data, are required to be re-coded. AI for science and medical uses is already pervasive. Due to the varying levels of accuracy and different spatial and temporal resolution of mobility datasets and other spatial data, integrating multiple data sources is a complex issue (Torre-Bastida et al. Sensitive datasets should be held in a secure environment that allows other researchers to access the data through a remote desktop in a private network and with pre-installed analysis software. Mobility studies at the aggregated level have more options in data sources, and an appropriate selection of aggregated data types is subject to the spatiotemporal scale. (2021) examined the spatiotemporal relationship by associating Twitter-derived mobility and COVID-19 cases in the State of South Carolina. Baidu EPS for the quarter ending June 30 . 2020c; Lamb, Kandula, and Shaman 2020; Levin et al. We identified three primary sources of human mobility datasets used in the recent COVID-19 studies and summarized the publicly available datasets categorized within these three primary sources: (1) public transit systems; (2) mobile network operators; and (3) mobile phone applications. The evaluation of urban vitality has been further deepened and refined with real-time and dynamic data (Wang, Liu, Wang, & Fu, 2021). For example, SafeGraph provides free access to various COVID-19 relevant datasets after completing a specific form and signing a non-commercial agreement. Although they are not, in most cases, open-source data (thus, they are not in the scope of this study), they provide essential contextual information (e.g. (RTTNews) - Baidu Inc. (BIDU) said that it deployed a multi-modal autonomous driving MaaS or mobility as a service platform that will provide AI-driven city transportation services in Guangzhou. It supports both WEB and WAP page browsing.
