Ambulance Drone Technology

Each year nearly a million people in Europe suffer from a cardiac arrest. A mere 8% survives due to slow response times of emergency services. The ambulance-drone is capable of saving lives with an integrated defibrillator. The goal is to improve existing emergency infrastructure with a network of drones. This new type of drones can go over 100 km/h and reaches its destination within 1 minute, which increases chance of survival from 8% to 80%! This drone folds up and becomes a toolbox for all kind of emergency supplies. Future implementations will also serve other use cases such as drowning, diabetes, respiratory issues and traumas.

RRFB Rectangular Rapid Flashing Beacons installed in Mission KS

Long Construction Project Comes to an End

RRFB Rectangular Rapid Flashing Beacons installed in Mission KS

Mission’s Johnson Drive opens all four lanes of traffic as long construction project comes to an end.

ELTEC Corp has added safety measures to Mission, KS Johnson Drive. By installing Eltec’s  RRFB (Rectangular Rapid Flashing Beacons) crosswalk safety features the four lane highway will notify drivers of potential pedestrians crossing. The RRFB is a rectangular shaped, high intensity signal head, which flashes in a wig-wag, rapid flickering pattern. The alternating signals provide direct, ultra-bright concentration as well as wide-angle intensity. The beacons are pedestrian activated: push button or passive detection (several options available).

Dear Mr. Marshall:

Thank you for your e-mail message of July 9 requesting an official interpretation as to whether the simpler flash patterns for rectangular rapid flashing beacons (RRFBs) that recently were successfully tested could be made available for use.

School Zone Safety Report

Every year, on average, 100 children are killed and 25,000 are injured walking to and from school, according to ATS. The company attributes many of these incidents to drivers who are distracted, speeding through school zones or illegally passing stopped school buses as children move toward or away from the bus. Enforcing traffic laws can help reduce these hazards, company officials said, but the demands on officers make it challenging for them to maintain a constant presence on school buses and in school zones on a daily basis.

Safety Feature For Pedestrians Has Undesired Consequence

Safety Feature For Pedestrians Has Undesired Consequence

Shankar Vedantam

New analysis finds that the countdown clocks telling pedestrians how much time they have to cross the intersection actually increase traffic crashes.


Many cities and towns have installed a safety feature for pedestrians at traffic signals, you might have seen them. When the signal changes to tell people when to cross an intersection, a timer appears. It alerts pedestrians to how much time they have to cross the road. Well, there’s new evidence that the safety feature might actually be having a dangerous and unintended consequence. NPR’s Shankar Vedantam joins us each week on this program to talk about social science research. And, Shankar, I know this countdown signal well. I see it as a driver, I see it as a pedestrian. What’s the danger here?

SHANKAR VEDANTAM, BYLINE: Well, the danger is that pedestrians are not the only ones who can see this countdown timer. Drivers can see the timer too and as the timer starts winding down to two or three seconds the driver knows the traffic light is about to turn red and that makes some of them speed up to get through the intersection.

GREENE: Well, beyond speeding up, you know, and potentially getting a ticket, is there even more danger here?

VEDANTAM: Yeah, I spoke with Arvind Magesan, he’s a researcher at the University of Calgary. And along with his co-author, Sacha Kapoor, they looked at the effect of installing these countdown timers at nearly 1,800 intersections in the city of Toronto. Now, the news is not all bad. The timers lowered the number of accidents involving pedestrians. In other words, when people know how much time they have to get across the intersection, it helps them get across safely or decide not to start in the first place. But the timers also increase collisions between cars. And Magesan told me there was one particular kind of crash that seemed to go up. Here he is.

ARVIND MAGESAN: The largest increase is in rear-end accidents and we think it’s because two cars approaching a light, who both see the countdown, the guy behind, he sees the two or three seconds and thinks, oh, the guy in front of me is going to floor it too, I’ll floor it and we’ll both get through the intersection. Whereas the guy in front thinks, OK, I only have two or three seconds left, I’m going to slowdown. And this is exactly the type of accident that would happen in that case.

New pedestrian, bike safety devices

Pedestrians who are crossing busy streets are often busy doing something else: listening to music, texting or talking on a phone. Those distracted walkers often fail to look both ways for traffic or follow other safety rules.

A study conducted during the summer in Seattle, Wash., may be the largest one yet to look at real-world pedestrians in this age of distraction. It found that more than 26 percent of the 1,000-plus walkers were using electronic devices as they navigated intersections where pedestrians had been hit in the past.
