Description The main discovery in this research project is that road traffic incidents can be detected more easily by algorithms when they incorporate contextual data. Road traffic incidents are undexpected events that disrupt traffic flow, eg accidents, breakdowns, illegal parking etc. Contextual data is data onevents that can be expected to cause disruption in traffic conditions, eg weather, school dates, sporting events, public holidays etc.

A key part of the methodology of the developed incident detection algorithm was a traffic forecasting algorithm names RoadCast. This algorithm improved on the state of the art by incorporating contextual data to improve forecast accuracy.

The original objective of this research project was to understand what a 'typical day in the road network' was, and to use this insight to improve incident detection. This project has achieved that by using RoadCast to forecast traffic in whatever particular day it is, and then detect incidents by looking for discrepencies with real-time traffic data.
Exploitation Route Both the traffic forecasting and incident detection algorithms are planned to be implemented by Siemens, this project's industrial sponsor.

In an academic sense, it has demonstrated that incident detection algorithms require contextual data in order to account for certain variations in traffic data, and that improvements in performance can be gained by incorporating them.

Incident detection algorithms are needed more and more by transport management centres to detect incidents. Existing manual methods such as monitoring CCTV are becoming unsuitable as transport networks increas in size, and funding decreases. Effective incident detection algorithms allow traffic management centres cover larger transport networks with fewer resources by helping operators detect incidents more quickly and effectively. This improvement in incident detection algorithm performance will be a step towards implementing more effective algorithms in traffic mangement centres, allowing incidents to be detected more quickly and effectively. Ultimately, this will result in less disruption from incidents on road networks.

Description The two main algorithms developed in this research are a traffic forecasting algorithm and incident detection algorithm. Both are planned to be implemented in Siemens systems, this project's sponsor. Firstly, Siemens won funding to use the traffic forecasting algorithm to better understand congestion. It is also planned that this traffic forecasting algorithm will be implemented within Siemens traffic management software, which will be used in traffic management centers across the UK. Finally, a trial of the incident detection algorithm in a traffic management center is on the way. The outcome of this trial will shape whether the incident deetection algorithm is also to be implemented in Siemens traffic management software.
