Distraction to drivers from bill boards on the roads

Today, I was driving to workplace. Enroute, while glancing at advertisements, I narrowly missed hitting a pedestrian. The lady crossing the road stopped and was looking at me, whereas I was watching billboard located at height, thereby missing the road view totally. It is mistake on my part. I also felt like there should not be any distraction to the drivers. Drivers should concentrate on the road traffic and possibly these billboards for others in the vehicles. Else, there can be accidents or near miss incidents like I had today.

How can we reduce unsafe acts on the roads and avoid accidents?

It is common to see various unsafe acts by vehicle drivers on the roads, like, talking on mobile while driving, driving in the wrong direction, parking the vehicles on the roads at unauthorized places, overloading, jumping the signals, etc.  A large number of vehicles are parked on the roads, causing congestion. Taxis, etc are parked near bus stops to pickup prospective customers, leading to reduced road width for other commuters. This is because no proper space is left during construction of houses, shopping malls, theaters, etc to maximize returns for them while not bothering about safety for public on the roads.
These acts endanger the vehicle drivers as well as other vehicle drivers and pedestrians. And it is not possible for the traffic police to catch all of them at all times.
Common public should be encouraged to take photographs of such unsafe acts along with readable vehicle numbers and local government should create a website for uploading of such photos by public and ensure some responsible authority in the control room to verify, prepare and issue penalty notices.   Surely, local authorities can make a killing by collecting parking fee on the roads instead of their own buildings because of parking everywhere on the roads. Non-payment should result in attaching the vehicle and/or property of the offenders.
Only when such public participation is ensured, road safety for all can be a reality. Else, it will be difficult for anybody to control and avoid accidents on the road.
