We had one more victim.
Fortunately, he didn't die.

I think the algoritm should avoid dangerous streets like it avoids heavy traffic routes.
The users could report the place as dangerous, like an alert.

Waze should include an option alert for dangerous places and/or streets. We live in a country with few streets that should be avoid.

Basta identificar e diferenciar os bairros das favelas. Tem software de GPS que faz isso, por o Waze não cópia? Ex: Favela Cidade de Deus, ao invés de cidade de Deus somente.

In some not safety countries as Brazil, we usually have cases of people that use GPS and go to "favelas" and die.
All police offices and city halls have reports for with the volume of homicides and crimes divided in regions and neighborhoods. Waze could use this to avoid passing thru this places, even taking more time, but it can make people safer.

Risk Zones
Unfortunately in Brazil we have some risk's zones, where there are robbery risks, or the routes lead to the places that you can't approach because doesn't exists security.
It would be great create, somehow, configure a way to avoid certain places/neighborhoods.
There are some cases that people got killed because entered in wrong places due to the routes suggested by the GPS.

I cannot say how important this would be. I live in São Paulo, Brazil. Half the time Waze takes me into high crime zones. I have friends that have been mugged during routes suggested by Waze in the past.

Las week, for example, Waze took me through 9 high crime slums! Can't express how afraid I was.

An additional feature that people could help other also police indicating higher risk area also assault

Route that avoid the dangerous areas, like streets reported burgled

Waze directed my wife through some scary parts of Los Angeles. She was alone and it was dark. It was just sending her the fastest way around an accident by taking her off the freeway and onto the side streets. But she drove through the hood and was really scared. She didn't know where she was, so she couldn't ignore the directions. Is there a setting to avoid high crime areas? If not, there should be.

I strongly concur with this post. I live in Atlanta and Waze routes me through one particularly dangerous inner city neighborhood that could easily be avoided. I have no idea how to provide this input.

It would be great if a setting were offered with a preference for using MAIN ROADS IN HIGH CRIME AREAS.

I prefer to use Waze at all times, but I often visit new locations that aren't the safest areas. I wish Waze allowed me to have a setting that favored main roads so that I'm not routed through strange or potentially unsafe neighborhoods. In order to avoid an unfair labeling of a particular neighborhood, perhaps it could be based on actual data and crime statistics. And rather than simply being and on/off setting, perhaps it could be a slider where you can adjust how tolerant the app would be. In certain situations, I'd rather my drive be 3 minutes longer, instead of cutting through an unsavory area.

If this feature were available, it'd be great if it were time based as well, because crime rates go up in some areas at certain times of the day whereas other areas have consistently high, or low, crime areas. So, for example, let's say a downtown, business district has virtually no crime rates from 7am-6pm. Then the app would route me through there just as it would any other area. If crime rates are statistically higher from 7pm-4am, then it starts to route me around this, when possible, much like how it routes around traffic. And in all of the above, whenever I say 'neighborhood,' I mean something very specific. Like it could literally be one street that's 3 blocks long.

I understand that some people live in or near high crime areas, and may have to use them during their normal commuting. To avoid problems with this, perhaps the app could detect when you are outside your typical area, and this feature wouldn't "kick in" unless you go outside your normal area.

I agree. Trulia already has a great crime mapping implementation that pulls from both SpotCrime and CrimeWatch and can even filter the data based on violent and non-violent crime. Having this data in a real-time, interactive, mobile app like Waze would be invaluable to motorists. I've heard rumors of a Microsoft patent that supposedly precludes implementing this feature, but it only covers pedestrian routing and explicitly excludes vehicular contexts. Since Waze is only used for vehicular routing, anyway, this should not be a legal issue Waze should be worrying about. If in doubt, consult Google's legal team. I'm sure they'll concur.

I get SpotCrime's reports which a crime mapping tool. While I was driving using ways the route it gave me might have been the shortest, it was certainly not the safest. It took me through an area with a well documented and violent drug trade.

Why don't they have "safest route". This could be determined by overlaying the navigation information with your crime mapping. The system would then avoid an area with an high occurrence of violent crimes. I think you'd find there are lots of people like me that can see the value in this and would be willing to pay for it.
