Alternative map of KSIs involving Heavy Goods Vehicles

In my previous post I presented a map created using Google Fusion Tables. This post shows an alternative map produced using the same data fed in to Google Maps. Due to limits on the file size, the collisions resulting in minor injuries have been omitted.

Vulnerable road users killed or seriously injured in collisions involving HGVS for the years 2005-2015




For a larger version of the map, click here.

'Vulnerable Road Users' refers to pedestrians, cyclists, motorcyclists, horse riders & mobility scooter riders. Due to the number of dangerous goods vehicles classed as 'Other', that category has been included and the maps will also include some collisions involving different vehicles in the 'Other' category.


STATS19 mapping implementation notes


These maps are based on the data from 2005-2015 inclusive (11 years of data), which has been edited down to make the file sizes more manageable. If you want the full details on specific a specific incident or want to search by area I recommend using www.cyclestreets.net/collisions/.

The data for "Journey_Purpose_of_Driver", "Vehicle_Type", "Make" and "Model" refers to the other vehicle involved where that has been possible to match*. For pedestrians, the data records which vehicle (first) hit them. For other road users we inferred a collision where there was just one other vehicle involved. When there were more vehicles it was not possible to infer which vehicles collided with which.

*Bicycles, horses and mobility scooters are all counted as vehicles.

For a few of the entries we have found errors in the data, such as missing location data which may means they have not been mapped. Examples of this are accident references 2005600GN6024 and 200504BB05106.

Care has been taken to avoid errors or emissions while creating these maps, however if you spot an issue please let us know.
