I'm a press photographer in the Netherlands and I see a lot of incidents for my work. By adding some tools, workers on the road can easily report problems and even instructions. For an example: When an accident happens there is sometimes a lot of debris on the road, even though some lanes are still open it's possible that there is debris on those lanes. By adding information, drivers can better adapt to the situations. Adding a tool to give traffic management the option to give information can improve the safety of the people who need to take care of the incident. It can also help if they can report regulating traffic by hand signals or you have to look out yourself. These things can improve the safety of emergency workers on the scene and prevent accidents. It would also be helpfull if you get a notification in traffic jams towards an accident to stay alert for emergency vehicles and motorcyclists and give them space to pass. I think a warning for people who speed near road works need to get a notification too. It can also prevent accidents if people get notifications for abrupt braking, a notification for about a minute can prevent accidents. In the end all temporary road closures should be easy to add for police and traffic management, it prevents a lot of work because there will be less people driving up to the closure and blocking traffic. I hope these ideas can help this great app.
