This dataset includes information from the past five calendar years and the current year to date, making it a comprehensive source for understanding traffic-related incidents in Denver.
Source and Origin

Collection
The Denver Police Department’s Data Analysis Unit, in conjunction with Denver Technology Services and DenverGIS, compiles this data into the dataset.
Data is collected through police reports generated at the scene of traffic accidents. Officers gather information through observations, statements from involved parties and witnesses, and, in some cases, surveillance footage.
Purpose and Motivation
The dataset is crucial for enhancing public safety and urban planning. It offers insights into traffic trends to improve safety measures and aids policymakers in infrastructure decisions. Additionally, it provides researchers with valuable data to study urban safety and traffic patterns, supporting a range of studies in public welfare and city development.

Sheet 1 shows the frequency of traffic accidents sorted by neighborhood, with the neighborhoods displayed along the horizontal axis (Neighborhood Id) and the count of traffic accidents displayed along the vertical axis.
Sheet 2 displays the frequency of different types of vehicles involved in accidents. The vertical axis shows the frequency, while the horizontal axis lists various vehicle types.The longest bar indicating that passenger car is the most frequently involved in accidents. The second most common is SUV.
This visualization is a geographic map of traffic accident counts by neighborhood in Denver. The map features circles of varying sizes overlaid on a map of the city, with each circle representing the number of traffic accidents in a particular neighborhood. The size of the circle is proportional to the count of accidents: larger circles indicate a higher number of accidents.
