This predictive model can enable emergency services to prioritise and allocate resources more efficiently. Authorities can make informed decisions to divert traffic and avoid additional congestion. This is crucial to minimise the impact on the road network and reduce the risk of secondary accidents. The model was built in Python using libraries such as Matplotlib and Seaborn for visualisation, Scikit Learn, TensorFlow and Keras for training the model and finally, the deployment was done through Streamlit and Render.
