28 days of hot summer, Zhejiang University IT youth help Hangzhou digital reform

This summer, the sun is like a fire. In the afternoon of July 29, a wonderful "encounter" occurred in the future community of Guanshu District, Gongshu District, Hangzhou. "guest". It is it, which is a new life for this "city village", which is also the blueprint for the blueprint of "Zhizhi Hangzhou · Livable Paradise". It is digital reform.

They are 28 members of the Summer Practice Team of Digital Reform Government Internship for Digital Reform of Zhejiang University. From July 11th to August 8th, from the Hangzhou Data Resources Administration, the Communist Youth League Hangzhou Municipal Party Committee and Zhejiang University School of Computer With the guidance of the Net Security College, they went to 9 jobs to actively participate in the construction of "Digital Zhejiang".

Digitalized inclusive people's livelihood, first solve the problem of "tip of the tongue" for the elderly

According to the "Population Data Bulletin in Zhejiang Province in 2021", in 2021, Zhejiang's 60 -year -old resident population was 12.52 million, accounting for 19.1%. Zhejiang Province has become one of the provinces with high population aging and aging. The degree is still deepening. In the exploration of Hangzhou in the "deep water zone" of digital reform, how should I make policies and service for the elderly in the elderly?

"People take food as the sky. We want to set off from the" food "on daily life 'food, food, housing and transportation'. On the first day when Classmate Fang Yanwen came to work in the Civil Affairs Bureau, he participated in the seminar of the "Smart Food Assistance" project, and communicated with companies such as Alipay, Sirui Technology, high -thickness technology, and other companies that provided technical support. Research topic.

"The paper is finally obvious. Although I read a lot of policy documents and news, the writing of the research documents and demand documents cannot be imagined out of thin air. At present, citizen cards and face -brushing payment are difficult to implement. We think of the reason for the elderly cafeteria." Two students followed the Civil Affairs Bureau's "One Old and One Primary" special class, and came to Gongshu District, the highest degree of aging, and investigated the construction status of the elderly cafeteria in the Yuyu Community, Xinhuafang Community, and Liuying Community.

After the field inspection, they found a problem. On the one hand, each elderly cafeteria has different billing systems and preferential policies. The invisible "digital barriers" make the elderly unable to use a card to eat throughout the city. On the other hand, some of the equipment of the elderly cafeteria need to be updated urgently. The existing payment method is single and requires access to the interface of Alipay and citizen cards to expand the intelligent payment method.

The two classmates said with emotion: "The people's livelihood is very large, including all aspects of social life; people's livelihood is also very small, and small is so small that it forms the rules of our daily life. If you want to really make a digital application for the people, It is necessary to spend energy from the needs of the people to achieve the real implementation of technology. "

Draw the subway traffic with Python into a "picture"

Before 2016, Hangzhou was joked as a "blocking city" and was high in the national urban congestion rankings. Over the years, Hangzhou has been continuously explored in improving urban traffic congestion. Today, Hangzhou has gradually solved traffic problems through digital reform. In this practice, members not only visited the specific cases of "digital congestion" in the Hangzhou city's brain, but also participated in the smart transportation construction project of the Transportation Bureau.

Hangzhou Metro Line 1, Line 5 and Line 9 were shocking during the morning and evening peaks. In order to explore the reasons behind this issue, Kim Mingming and Zheng Yuewen of the Practice Group used Python to visualize the existing subway traffic data.

At present, Hangzhou Metro passenger traffic data is recorded with the OD QR matrix table. The "O" stems from the English "Origin", which points out the place where "D" originated from the "Destination" of English, pointing out the purpose of the trip, pointing out that the purpose of the trip is land. Simply put, it is describing traffic flow from regional A to regional B, that is, the degree of congestion from one place to another path.

Classmate Zheng Yuewen shared: "Our processing ideas are roughly divided into three steps. First, the subway sections and site information are converted into road network charts through QGIS and Python; Stack to the road section; finally, use Python to see the road network diagram after the overlay traffic. "

The instructor responsible for this project mentioned that in recent years, Hangzhou has built several new subway lines. One of the goals is to share the high -voltage flow of the main urban area. After that, a reasonable route optimization will be made based on this road network traffic chart.

Student Jin Mingming also said: "Our current algorithms are not perfect. If there is still time, we still need to consider the intention of the passenger's real travel, the subway congestion status, and the number of intervals in the middle. Realize further optimization. "

Open the "last mile" of the community in the population data

"There are nearly 9,000 people in the harmonious community. It is difficult for us to complete the data management of the population alone." Social workers in Gongshu District's Holy Community of Gongshu District introduced Li Yixin, Chen Xiaoting and Gao Yifan in the practice group.

In order to help the Gongshu District Data Resources Administration of Data Resource Management Bureau in the Practice Group, these small partners have visited more than 20 front -line staff in the grassroots community in the grassroots community in order to help Gongshu District. Nearly 30,000 words of interview records and a research report of more than 30,000 words. The members of the Practice Group found that in the collection of population data, the community police office is mainly responsible for the flow of population, and community social workers are responsible for the permanent population. If these two parts of the data can be opened, the integrity of the basic data of the population can be guaranteed, and their duplicate work can be reduced.

In addition, in order to make digital applications truly help social workers reduce the burden, they also conducted in -depth "diagnosis" for the implementation of community intellectual Zhizhi online platforms. "After investigation, we found that the unwillingness to use social workers is related to the lack of platform function construction, and we have made optimization suggestions from the perspective of software development and use. We believe that through problem feedback and solution, this platform can replace the compartment to achieve an efficient and convenient population. Data collection, update, and circulation. "Gao Yifan, a member of the Practice Group, said.

In 28 days, members of the Practice Group actively put into work, accumulated more than 30 key project construction of digital reform, participated in more than 100 special class meetings, and carried out the theme of "focusing on the new model of" new models of digital reform in Hangzhou ". Research, consulted hundreds of documents and materials, visited more than 20 public sectors, enterprises and institutions of cities, districts, streets, and communities to complete more than 50 articles covering the government, universities, enterprises, and residents. Form the theoretical results of more than 120,000 words. In addition, it also organized more than 10 foreign practice and volunteer service activities, attracting the participation of 8 practical teams in the school, and the activity services directly radiated more than 1,000 people.
