Centered on the . 2020; Tobas 2020). No potential conflict of interest was reported by the author(s). It quantifies the intensity of human mobility as an immigration index (I-index), an emigration index (E-index), and an intra-city index (C-index). In this section, we summarized the three major applications of human mobility data in COVID-19 studies: (1) revealing spatiotemporal trends and patterns; (2) examining the association of human mobility with COVID-19; and (3) integrating the simulation and predictions of COVID-19 transmission. Watch the recap above to hear MOBI Co-Founder and COO, Tram Vo, share the MOBI Technology Stack (MTS). Cuebiq Mobility Index, which is also derived from mobile location data, quantifies how far mobile devices move each day by using a derivative factor indicating the distance between opposite corners of a box drawn around the observed locations (Cuebiq Inc. 2020). We study the theoretic and computational principles of data science, its systems, and its novel applications in many different areas of application. Institute for Health Metrics and Evaluation Population Health Building/Hans Rosling Center, 3980 15th Ave. NE, Seattle, WA 98195, USA UW Campus Box #351615 | Tel: +1 . 2021).

Code and data for analyzing Baidu mobility data, Additional license, warranty, and copyright information, Article 22 of the Copyright Law of the People's Republic of China, University of Virginia Biocomplexity Institute. 2020), Descartes Lab Mobility Index (Warren and Skillman 2020), and indices from SafeGraph (Huang et al. The quality of mobility data depends on data types, and this makes it challenging to assess data quality without careful comparison studies. Prev Next Eric Walz 2020). In the future, we will conduct a broader human mobility data review, combining both conventional small data and new big data. We identified three major sources of mobility data: public transit systems, mobile operators, and mobile phone applications. "Today, we are in the midst of a major cycle of technological development, with new technologies emerging in almost every industry, from new energy to space exploration, biomedicine, smart manufacturing, and more," Robin Li, Co-founder and CEO of Baidu said at the conference. Today, the average car generates 25 gigabytes of data per hour - an already large number that is set to rise exponentially with the emergence of electric and autonomous vehicles. 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%. Kaiwu 2.0 Empowers Industrial Transformation with AI. 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. They allow us to count visits and traffic sources so that we can measure and improve the performance of our sites. Recommended articles lists articles that we recommend and is powered by our AI driven recommendation engine. Li et al. Smartphone users can now interact with DuXiaoxiao via the Baidu App, the first step towards a future when personalized digital human service becomes commonplace. For the full year, ending in January, earnings are expected to decline 5.3% year over year to $7.67, while full-year revenue of $19.24 billion would rise about 2.2% year over year. Baidu aims to make the complicated world simpler for users and enterprises through technology. As one of the largest social media, Weibo is considered as the "Twitter" in China. UMMI, developed by the project team at the Maryland Transportation Institute at the University of Maryland, is based on integrated and cleaned mobile phone location data from multiple sources that represent person and vehicle movements (University of Maryland 2020). To the best of our knowledge, there is no current review summarizing the human mobility data usage in recent COVID-19 studies. Included in registration is access to our daily newsletter - Quantum Energy Daily, a summary of all Quantum content delivered into your email inbox each evening. Discover historical prices for BIDU stock on Yahoo Finance. "Government agencies, academia and the industry will collaborate more closely to build high-quality quantum devices and cultivate quantum technology talent, taking the first steps toward creating a quantum computing industry chain," Baidu Research predicted. Three areas Baidu Research covered that Alibaba did not are autonomous driving, inclusivity, and the integration of quantum hardware and software. You can also change your choices at any time, by hitting the 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. Thus, the similarity/disparity of multi-source mobility data can be explained by the spectrum of the population being captured. Baidu is the first Chinese company to join the group that includes US tech giants such as Amazon and works on AI ethics. For index-based mobility data, BMI has been extensively used in Chinese studies to examine how the virus spread was affected by the mobility from or to Wuhan and Hubei Province, where the first wave of COVID-19 appeared (Chen et al. 2020). 2020b; Lau et al. All materials and images are for informational purposes ; All materials and images must not be used for commercial purposes ; All materials, images and any part thereof must include this copyright notice . It supports both WEB and WAP page browsing. Meanwhile, Alibaba's green predictions centre around how AI can help connect the dots of things like renewable energy. For the first quarter, the Zacks Consensus Estimate for revenues is pegged at. For example, the OpenSky-Network provides freely accessible airline flight data since 2019; however, it does not provide every global flight movement but only those ADS-B-equipped aircraft seen within the coverage (The OpenSky Network 2020). How the automotive, mobility, and transportation industry embraced transformation in 2021 to drive resiliency and innovation into 2022 and beyond. Such data can indicate connection and interaction across places under the restricted travel ban, and this information cannot be revealed by social activity mobility data. Now more than ever, the use of and access to human mobility data are imperative to controlling the spread of communicable and infectious disease outbreaks. Solidaridad las Torres 1942, Metepec. Accordingly, an individual train passenger's mobility pattern can be reflected as the network distance between the boarding station being the origin and the alighting station being the destination with the recorded travel time (Carten, Di Francesco, and Martino 2020; Hu et al. 2014; Lee et al. Based on the geo-tagged information in the sampled Weibo data, we built the Weibo mobility index by provinces and prefecture cities in China. Otherwise, Baidu will pursue legal responsibility according to law. Nevertheless, the effective integration of multi-source datasets has not been fully achieved. With a dramatically reduced unit cost of RMB 250,000 (~$37,000), deployment of Apollo RT6 represents a key step towards a world where taking a robotaxi will be half the cost of taking a taxi today. (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. 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. For example, remote sensing data have helped detect air quality, traffic, and human activity changes with a large spatial coverage during different phases of the pandemic (Liu et al. 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. 2014). The core feature with Baidu Moible, of course, is still search where most of Baidu's revenues are from. In particular, the research arm expects AI-powered computational biology, spurred on by the success of mRNA vaccine technology, will be on the rise. bing. 2020; Fang, Wang, and Yang 2020). Researchers have proposed many methods and developed tools to integrate various spatial data. 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. The public available mobility datasets, such as Google Community Mobility Report, Apple Mobility Data, Baidu Mobility Index, Foursquare Mobility Data, and Descartes Mobility Index, presented in the study are shared and updated by Spatial Data Lab at Harvard University on Harvard Dataverse (https://dataverse.harvard.edu/dataverse/data_ncov). Four approaches have been commonly used to estimate human mobility: public transit-based flow, social activity patterns, index-based mobility data, and social media-derived mobility data. Third, mobility control is observed to have a time-lag effect on the virus transmission and such effect varies across the geographic contexts and the timeline of the pandemic. Data security in transit is also critical as this ensures that data is protected while being transferred in-between networks, such as during the upload, download, and data transmission steps of processing and backup. Commonly used social media platforms for gathering human mobility patterns include, but are not limited to: Twitter, Facebook, Instagram, WeChat (China), and Weibo (China). The above mobility-based studies reveal some common findings contributing to the COVID-19 control and intervention as below. The site will offer more than 40,900 square feet of available space and the capacity for over 40,000 servers. 2020; Xiong et al. across and within a fare zone). For index-based mobility data, BMI has been largely applied in disease modeling in Chinese studies (e.g. Mobility data were made public by Baidu and manually transcribed from Qianxi Baidu and are stored here. We thank Baidu for making these data public and encourage them to continue to do so. For example, Mohammadi, Rajabifard, and Williamson (2010) proposed a tool that facilitates data harmonization through the assessment of multi-source spatial datasets against many measures. More data limitations regarding social media-derived mobility are discussed in Section 6.2. 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. 2020; Shen 2020; Zhuang et al. But progress still requires relentless efforts and new paths for a better future driven by technology. Baidu owns the copyright of all the materials in this website. 2013). Multi-source data integration not only requires technical tools and considerations, such as the match of datasets geometrically, topologically, and with correspondence of attribute (Usery et al. 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. 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. Most of the public transportation data from these transportation systems are provided by data service companies, but there is no standard data format. 13.54 %. driven by cloud and other AI power businesses. 2020), and the UMMI has been applied to model the impact of stay-at-home orders on human mobility (Xiong et al. BAIDU, INC. company earnings calendar and analyst expectations - Upcoming and past events | Nasdaq: BIDU | Nasdaq. Government customers, mobility operators, energy companies, infrastructure firms, and enterprise businesses in many countries signed up to use . 2020; Huang et al. This value gives a seven day rolling (mean) average to avoid it being distorted by weekends and bank holidays. This valuable (often extensive) user-generated information obtained from social media platforms and their derived mobility indices greatly facilitate (near) real-time human mobility monitoring during the COVID-19 pandemic in an active, less privacy-concerning manner (compared to the mobility records collected from phone records and smart cards). Baidu has developed several tools that are effective in building awareness and screening populations, including an AI-powered, non-contact infrared sensor system that provides users with fast. Today, Baidu's AI solutions for thermal power plants are helping to reduce coal consumption, opening a path towards reducing carbon emissions by 6 million tons a year in China. The COVID-19 pandemic poses unprecedented challenges around the world. This webinar will give an introduction to this Weibo mobility index, including data sources, methodology, comparative . 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. Despite reporting solid growth in its top line, the company posted a 14% drop in non-GAAP net income to $2.95bn.The company saw expenses or cost of revenues jump over 17% in fiscal 2021 due to a rise in content costs, traffic acquisition costs and expenses related to its new AI business. Within public transit datasets, the scheduled timetable data often face fewer concerns about privacy issues. The timing, effectiveness, and stringency of policy implementation are crucial for the success of COVID-19 control efforts in different countries. Space exploration, humans merging with robots, and sustainability factors made both company's lists, albeit with different approaches or outlooks. We also present challenges and future directions of using mobility data. By closing this message, you are consenting to our use of cookies. For example, the connection of air flights from China to other countries can serve as an essential indicator to show how the virus may have spread outside of China (Lau et al. The OD flow indicates if the mobility value/index provides inter/intra-region movement information. We measure how many people read us, For instance, it can inform citizens about real-time information of arrival and departure of trains and buses, help them to choose options for last mile connectivity and help in . The data for other modes of public transit have a greater variation in terms of coverage and quality depending on the region. 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; Lee et al. Please see the Warranty section below as we make no representation as to the suitability of these data for any purpose. Each of these datasets consists of different variables and indices to distinguish people's movement activities as a response to social restriction policies. Despite that these open-sourced human mobility datasets (usually big in nature) have established a venue where rapid monitoring/supervision of human movement with high spatiotemporal scales can be achieved, essential contextual information on these monitored travels is often missing, as such information is unlikely to be released due to privacy concerns. Iacus et al. This information can help measure the access frequency to the points of interest (POI), such as residential areas, shopping centers, hospitals, and recreational and public facilities. the researchers note that the android versions of the browser are built using the baidu mobile tongji (analytics) sdk and that security firm lookout confirmed to them that there are 22,548 unique app package names that contain the sdk. The air flight data are useful in estimating the population flow both between and within countries and regions. As a result, researchers are offered more freedom to construct desirable mobility indices at various spatiotemporal scales. international travel bans, national border closures, lockdown orders, and limited gatherings) is the primary and effective strategy to reduce infections and curb the transmission of COVID-19 (Yang et al. 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. 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. Apart from socioeconomic data, some big data sources have been widely applied in COVID-19 studies as well. 5 Howick Place | London | SW1P 1WG. Furthermore, more studies are needed to develop interactive geospatial web portals to allow researchers to query, extract, visualize, and share the derived human mobility data. Baidu Mobile Assistant is the application where you can find software for your Android and which we expect to be duly monitored by the Chinese government. When typing in this field, a list of search results will appear and be automatically updated as you type. Intellectual Property Statement (translated by Google translate via the University of Virginia Biocomplexity Institute). Given that Baidu operates an L4 autonomous taxi service in a 60km2 area of Beijing, it's not surprising that the list might refer to robocars as "the next generation of vehicles that will give rise to a revolution in transportation," although the company doesn't give too much detail on what that will look like. survey and public transit system), the growth of telecommunication devices and mobile applications has significantly changed the way of data production and processing. This will enable researchers to collaborate more efficiently without sacrificing data privacy. Finally, social activity data are appropriate for studies on the different types of human mobility to various places and by various trip modes. For example, OpenSky Network collected crowdsourced air traffic control data broadcast by airplanes and shared a dataset of global flight movements, which include aircraft identification number, model type, origin, destination, first-seen and last-seen timestamps, latitudes, and longitudes, etc. Oil futures: Crude retreats from earlier highs, Brent dips below $92/b. The storage of mobility data must be secure and must disallow any unauthenticated and unauthorized access. Baidu Browser for Windows Phone 7.5 is a mobile browser presented by Baidu Mobile Team. Human mobility datasets characterize the pattern and trajectory of human activities, including, but not limited to, walking around local neighborhoods, driving to workplaces, or utilizing public transportation. Mobility data collected via a passive manner (mobile phones and wireless networks) tend to have high representativeness because of their high penetration ratios. Sogou.

In contrast, Baidu Mobility Index offers inter-city and inter-provinces population flows index with comprehensive big data sources. In the U.S. studies, Cuebiq Mobility Index and UMMI have been utilized to explore the relationship between mobility and virus spread; however, other types of index-based mobility data were relatively less used (Zhang et al. Mobile network operators can track people's locations in the Call Detailed Records (CDRs) that contain information about the time of the call and the cell tower to which mobile phones are connected when the call took place (Oliver et al. 2020a). Time-series Clustering for Home Dwell Time during COVID-19: What Can We Learn from It? To measure places connectivity, Li et al. of 2019 and 2020: Control variable: 24 Oct 2022. A full explanation of Trend's relationship with Baidu should be provided. https://www.mckinsey.com 915b5091-0d7e-44d2-a8c4-cf08267e52fe Unlike the aforementioned datasets, Safegraph initially provides social activity data at the census tract level, and the data can be easily aggregated to the county and state level. Baidu EPS for the quarter ending June 30 . Kang et al. Search Engines. 2011; Changruenngam, Bicout, and Modchang 2020; Yue and Hu 2021). Keynotes, panels, and working sessions are part of the program for our international attendees. For example, Zhou et al. Most of the data services provide either Application Programming Interface (API) or direct download links, and the historical travel data are usually accessible. The published data have Digital Object Identifier (DOI) and are open to all communities. The dataset is published in GitHub and is free to use. 2016). (2021b) explored the correlation between COVID-19 cases and the place connectivity index summarized from Twitter in Westchester County, New York, which was one of the early COVID-19 hotspots in the U.S. Another dominant application of mobility data is modeling COVID-19 transmission by simulating and predicting the virus spread over a certain period of time. (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. Read our latest research, articles, and reports on the future of mobility on the changes that matter most for the challenges and opportunities ahead. For example, mobility data retrieved from public transit systems are mode-specific and lack the holistic views of overall human spatial interactions. Human mobility data, generated passively or actively from the movement of billions of people around the world, are intrinsic Big Data that are characterized with the typical five challenging Vs (volume, velocity, variety, veracity, and value) (Zikopoulos and Eaton 2011; Gudivada, Baeza-Yates, and Raghavan 2015; Li 2020). We use cookies to improve your website experience. There are many expressions of mobility data, including footfall, catchment areas, dwell-time analysis and visits to different types of place. Despite the notable heterogeneity presented by the aforementioned sources, studies have shown that the fusion of multi-source mobility datasets can mitigate, to a large extent, the intrinsic bias within each mobility source and can provide a holistic view of mobility dynamics by capturing a broad spectrum of the population (Montero et al. Lastly, the University of Maryland Mobility Metrics and Social Distancing Index (UMMI) contains six mobility metrics: the percentage of staying home; the percentage of reduction of all trips; work trips; non-work trips; travel distance; and out-of-county trips compared to the pre-pandemic benchmark through a multi-level weighting procedure (University of Maryland 2020). While such datasets are often small in size and easy to handle, they offer limited flexibility for studies on different spatiotemporal scales and limited transparency in how these mobility data are generated. Mobility datasets retrieved from public transit systems, such as bus, train, ferry, metro, and air flight, represent the aggregated human mobility. Descartes Lab Mobility Index (Descartes Lab 2020) is calculated as the median of maximum distance mobility across all position reports within the threshold of 50 meters. BaiduBrowser. BAIDU INC-SP ADR 108.66 USD -6.39 -5.55% Open Tracking Covid-19 580, 145 New cases reported worldwide, Oct. 5 6, 554, 197 Total deaths reported worldwide Germany 132,494 Most new cases today 12,. 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. 2020). Baidu aims to serve as a cornerstone of these efforts, contributing to basic research, basic technology and underlying innovation. 2020a; Li et al. However, most of these mobility data suffer from representativeness issues as the data are limited to only mobile phone users or app users whose locational function is turned on. Your Consent Options link on the site's footer. These data have been regularly updated and released to the public for the purpose of supporting public health authorities and the research community in response to COVID-19. While most other data sources cover various countries, the BMI only covers Mainland China. The reduction of infection caused by mobility control is observed to be relatively weaker in places where the outbreak occurred later (Zhang et al. 2020). 2020; Ghader et al.
