Is your commute a death trap?

How dangerous is your commute? The answer may depend on the weather.

In addition to speed traps and red light cameras, Njection.com is now offering people the option to view the traffic accident history of a route based on past weather conditions using the Njection Mobile iPhone application.

Njection took five years of accident data from the National Highway Traffic Safety Administration and merged it with global weather conditions from WeatherBug.com. Using Microsoft Virtual Earth, this mashup enables people to see what accidents have occurred in a particular area, and if they want, filter the data to show what accidents have occurred based on weather conditions that are similar to the current weather conditions.

This means that a trip to the mountains may be relatively risk-free in sunny weather, but is an accident magnet when it rains or snows. The maps also offers the option to limit the data to past accidents that occurred within a four-hour window based on the current hour.

People can test the mashup on Njection's Web site. The company is waiting for final approval from Apple for this version of the product.
