Traffic Signs Recognition Using CNN & Keras In Python With Source Code
The Traffic Signs Recognition Using CNN & Keras In Python was developed using Python Programming with CNN & Keras, There are several different types of traffic signs like speed limits, no entry, traffic signals, turn left or right, children crossing, no passing of heavy vehicles, etc. Traffic signs classification is the process of identifying which class a traffic sign belongs to.
A Traffic Signs Recognition Python project example, we will build a deep neural network model that can classify traffic signs present in the image into different categories. With this model, we are able to read and understand traffic signs which are a very important task for all autonomous vehicles.
This Python Project Using CNN and Keras also includes a downloadable Python Project With Source Code for free, just find the downloadable source code below and click to start downloading.

Summary
In this Python project with source code, we have successfully classified the traffic signs classifier with 95% accuracy and also visualized how our accuracy and loss changes with time, which is pretty good from a simple CNN model.
