Cycle Collision Overview
Outline
The document serves the preliminary analysis and summary statistics for the cycle-related traffic collisions happened from 2017 to 2021 (five-year period) in Hong Kong. Following will be included:
Summary Statistics:
- Trend by collision type across years
- Number of injuries (All/KSI) across years
- Types of injuries (ped/cyclist?)
- Age distribution
- What is the main vehicle
- Location (road hierarchy)
- Vehicle action vs. cyclist action when collision happens
- Cyclist action vs. cyclist action when collision happens
What are the collisions? (accidents table)
Trend by collision type across years
Note
See if area or line is better.
KSI Only
Severity level of the collisions
Location (road hierarchy)
Note
Road hierarchy seems not important in explaning cycle collisions?
