This repository contains code and links to data that was used to analyse traffic patterns in Bristol.
- Car accident data available here. Data from 2014 and 2015 are used in this analysis.
- Bristol Journey Times data available here. A snapshot of data up until 07/04/2017 14:47 UTC was used.
- The speed and time are measured based on the number of cars passing between two traffic monitoring cameras (no car quantity given)
- The coordinates of each monitoring point are latitude and longitude of the middle point between the two monitoring cameras (this can be the same for two routes in opposite directions)
- Data between August 2015 and January 2016 were disregarded (January 2016 onwards are the most trustworthy)
- The travel time is in seconds
- The timestamp marks the start of the journey
- The speed is in mph (converted to meters per second in this analysis)
- Simple weather data (rain measurements in particular) available here.
- How do weather patterns influence the traffic load?
- Is there seasonal variation in the journey times?
- Is traffic bad at specific locations at specific times of the day?
- How do large city events / festivals affect congestion?
- If car journey times are bad, how does this affect alternative modes of transport?
- Can congestion data link with sentiment mapping?
- SVG interactive road map; on click show travel time series below
- general time range slider; change the colour of the road depending on the usage
