Satellite navigation systems not representing crossroads junctions as give way / stop

Has anyone managed to get any engagement with Sat Nav companies to get their data updated? We are aware of some sites in our area where collisions may partly be due to such systems not showing the need to give way or stop at crossroad junctions, and therefore drivers may potentially emerge from the minor road without reacting to the road signs present.

Satellite navigation systems not representing crossroads junctions as give way / stop

I'm not sure if I understand this question correctly but if it suggests that some people are relying on Sat Nav's when approaching crossroad junctions etc then it really doesn't make any sense at all. We all know that Sat Nav's are an aid ONLY to navigation and should NEVER be relied upon for their accuracy.
Drivers should always read signs appropriately and not rely on a funny little voice telling them on the sat nav that they should stop or give way. I've never heard anything so ridiculous.
As for asking Sat Nav companies to update their systems, should they also be asked to update them to show when the hazard lines change to double solids?

Yes we had a recent Fatal RTC where one of the hypotheses is that the Sat Nav was a contributory factor as the driver was a US citizen on holidays who over-shot an already well engineered crossroads. I sent a letter to 3 manufacturers via their media department. Garmin have acknowledged (it was one of their devices)and advised it has been passed to their cartography department for investigation.

We recently had 2 collisions where vehicles drove in to a 5m high wall across the Highway where it had been stopped up and built over. Resulting in a turned over vehicle and fractured wrist. It was previously one way for 30+ years in the opposite direction to the direction the vehicles had traveled in.
We checked 3 different Sat Nav systems and found none directed vehicles through the route BUT when we used a mobile phone Sat Nav it did direct us through the route as a pedestrian.
I think this highlights how people can blindly follow Sat Nav's. I'm sure there are many other examples.

Manufacturers factory fitted sat navs often charge for updates so many of these sat nav systems are never updated. Mine hasn't had an update since it was installed in 2004 and it often shows me apparently driving across fields. However no sheep (or walls) were hurt during this time.

I have tried several times to get google to correct their maps, without getting quick results even when their streetview shows that their map is wrong.
From a quick search through some 10000 injury accident stories from Police, I found about 6 mentioning sat nav. In 2 of these the driver had made the mistake of following sat-nav and not paying attention to signs: in one the driver continued straight on past a give-way, and in another the driver tried to turn at too high a speed, having failed to slow down after passing the advance direction sign or seeing the junction as they approached it. In the others the drivers had been looking at their sat-nav rather than watching the road or traffic in front of them.
One of our accident cluster sites is a crossroads of 3 A-class routes, and traffic following the continuous numbered route has to give-way and turn, rather than continuing straight through. At least one route finding website (bing) didn't mention this junction at all to traffic which has to give-way and turn left.

Satellite navigation systems not representing crossroads junctions as give way / stop

recently driving in the UK (I now live in Jersey) I was using Google maps to get me to an unfamiliar location. I was caught out more than once by google saying the next junction/turning was miles away when 'suddenly' there was a give way or traffic signals or some other reason I had to stop.

As a road safety professional I am perhaps more aware as a driver than many others would be who could easily just sail straight through without realising.

Google seems quite good in urban areas, but when moving onto rural roads it is very poor at advising about some fairly major junctions if you're going straight on.

If you're logged in and can find it, there is a 'propose edits' function in google maps, but it doesn't seem to exist all the time. As for other providers - Good luck!
