A navigation system for finding an optimum route to the destination using traffic incidents information provides a novel approach to enable a user easily and quickly to select which incidents should be avoided. The user can easily identify the important traffic incidents because the system can display only the traffic incidents on the calculated route as well as all the traffic incidents in the converged area. The user can select the incident to receive more detailed information including a live image of the traffic incident and specify one or more incidents to be avoided on the route to the destination. The system calculates a new optimum route to avoid the specified traffic incidents. The traffic incidents are illustrated on the navigation system by two or more different icons representing predefined types of traffic incidents

The invention relates to methods of dynamic chemical imaging, including methods of cellular imaging.
