Sensor Trippers for Slide Areas on Canyon Roads

Author : Lance Winslow
Each year many motorists die on two-lane canyon roads. Many of these accidents are caused by people who are intoxicated or fatigued, some from mechanical error and some from people in a hurry crossing over double yellow lines into oncoming traffic. A percentage of these head-on collisions from those straddling the double yellow (considered a "Malibu Felony" in their California traffic court there) or in the wrong lane come from people avoiding debris, which has fallen into the road way due to erosion, heavy storms or small avalanches from sound waves or seismic activities.Many canyon roads are prone to this type of issue due to steep cliffs above; most of these areas have signs warning motorists of the dangers. You have seen these signs; "Caution Falling Rocks" with picture of rocks falling from a cliff onto a car. Not too reassuring to say the least, often we laugh and say; "oh great" like what am I suppose to do if a giant boulder decides to let lose? But most accidents on canyon roads due not happen from a rock actually falling on the car, that is more like lightning striking you. Most accidents occur as motorists try to avoid the debris, which has already fallen onto the roadway.Having traveled around the nation for the last five years, I have always enjoyed the scenic highways, the ones with the dots along them in your $5.00 Wal-Mart road atlas. As a motorcycle enthusiast I have always chosen the roads less traveled and occasionally enjoy opening the throttle and enjoying the canyon turns.We need a warning system which has sensors, similar to motion detectors when rocks have fallen onto the roadway ahead or around the next corner in those cautionary areas. One way to do this is to use motion sensors, which send out a wireless signal to small reflector repeaters around the corners to warn those approaching that in fact today there is debris on the road and you will need to watch out around the next corner. This will give the drivers or riders time to slow down and respond. Currently there are many technologies used to alert drivers of deer crossing the road ahead or icy roadways. A diamond shape sign which is already in place to warn of a sharp corner ahead or falling rocks area can be outfitted with a blinking amber light in the event of debris on the road ahead using these wireless sensors and reflective repeaters, lets think on this. The costs are nominal and the rewards of saving lives are great indeed.Lance Winslow - Online Think Tank forum board.
