That...sounds dangerous.
- 9nGQluzmnq3M 7y agoI presume the red is unilateral, meaning they don't (immediately) change the other side to green in response.
- manojlds 7y agoYeah that makes it a lot safer. But still, what if two cars are approaching the signal and they end up rear ending?
- ultrarunner 7y agoEven still, much like in India where drivers will learn to ignore the the punishing light, it could be drivers in France will learn that running reds does not increase a chance of collision because it’s only a signal of speed.
- mrpopo 7y agoIncreasing a chance of collision or not is not the same as losing a minute over a traffic light or annoying a few people. It does not appeal to the same emotions, it has a much deeper meaning. I believe the comparison is flawed.
- tgsovlerkhgsel 7y agoIt only has to increase the chance of getting a really expensive ticket and points on your license to discourage that.
- ultrarunner 7y agoWhen a light turns yellow, a driver has to make a very quick calculus of a number of factors, including estimating stopping duration and distance, traffic presence, penalties, even judgement from other drivers. Some people will place more weight on one or another of those factors. If there is any significant portion of the population that places weight on "this isn't a real red light; it is only meant as a nagging signal" then it seems that the chances of a miscalculation (and high-speed collision) become greater overall.
- tgsovlerkhgsel 7y agoThe obvious solution would be to combine each nagging signal with a red-light camera, at which point it becomes very "real".
- geon 7y agoHow would it be more dangerous than triggering the transition by a timer?
- manojlds 7y agoIf it's unpredictable, can I end up being rear ended by someone behind?
- Enginerrrd 7y agoBecause humans anticipate things and this simultaneously changes their intuition about the light they're anticipating after confirming that it's particularly relevant, essentially maximizing the chance the run a red light, or slam on the brakes and get rear-ended.
- clort 7y agoperhaps if the sensor is not on the light, but some distance away that would be a lot safer? (I don't know how it has been arranged)
- pvaldes 7y agoPlaced some distance away. Happens also in Spain next to schools or hospitals. Is designed in special casses when humans need to use often a crosswalk, not to manage trafic in a crossroad. It works well.
