危險都市

Abstract

摘 要 現今台灣因高度經濟成長與都市化，衍生的犯罪問題也越來越多。本研究欲設計一個整合性平台，供使用者選擇自身關心的變數，經由中華民國內政部警政署提供的資料，並透過統計運算各筆資料，最後以視覺化地圖呈現台灣各城市的治安排名。

本研究使用Shiny套件建立一個互動式介面，其中分為前端的UI與後端的Server兩大部分，UI用來描繪網頁的呈現方式，Server則為後端伺服器，使用者於前端勾選欲關注的細項變數，後端則以勾選的變數資料進行主成分分析，並計算出各城市的排名，依設定好的區段將所有縣市分為三個等級，並以顏色來表示，再利用Leaflet套件將顏色繪製於台灣地圖上，最後傳送到前端的介面顯示。

這次的研究，我們運用了我們在統計系所學習到的專業知識，建構一個可提供個人需求來進行統計分析的系統，利用淺顯易懂的互動式介面，即可讓使用者得到大筆資料經過複雜的統計分析後最後的結果。

Abstract

The measurement and evaluation of crime is an important issue, especially for the developed country. In this research, crime data from the National Police Agency are used to analyze and construct a user-friendly platform. Users can choose the items of crime that they care about, and the ranks of public security for each city in Taiwan are shown via a visual map.

Shiny package in R program is adopted to construct the integrative platform. Two modules are essential, including UI for the front-end and Server for the back-end. Based on the items of crime and year that user selects in the front-end, the comprehensive data analysis runs in the back-end. The principal component analysis method is adopted and the values for evaluating the dangerous are provided. Finally, the level of danger is displayed on the Taiwan map by Leaflet package.

In this project, we use the expertise learned from the Department of Statistics in the college. We provide an interactive interface to make the statistical results easily and clearly.
