High Schoolers Use Arduino Kits to Design Safer Railroad Crossing Systems in Westchester, NY

 

The Digital Arts Experience held its first ever Design Challenge on Saturday, December 3rd. The challenge focused on rail safety, more specifically, developing safer systems for rail crossings. Given the increasing number of train accidents and in the light of the recent bills signed by Gov. Andrew Cuomo to require the state to study rail crossings and assess their safety, we felt that High School students would be the ideal candidates to innovate and improve the dated and ineffective technology that is currently being utilized.

The teams were provided Arduino Uno boards, which are inexpensive microprocessors, and simple buttons, switches, LEDs, motors, and sensors to create their systems. Teams from Putnam Valley High School, Mamaroneck High School, and Mt. Vernon High School registered to face this challenge. The teams had approximately five hours to design, build, and test their systems, and everyone at The DAE as well as the judges were absolutely blown away by what the teams created.

_mg_3743The students from Putnam Valley High School created a self-aware system with sensors and volumetric cameras that could assess a car or any other object on a track (i.e. a fallen tree, power line, etc.) and notify the train operator and MTA control room. What’s more is their design had multiple levels of redundancy that took human error out of the equation. For example, if the system detected a car on the tracks, the train operator, and MTA control would be notified. If the train started to approach the zone in which it could safely stop before colliding with the obstruction and the train operator did not start to slow down, the system would slow down the train automatically. This system was thoughtfully designed and excellently executed. Using the simple technology provided, they demonstrated exactly how their system would detect, communicate, and intervene when needed. It had layers of systems that constantly checked on each other to ensure that no matter what, an impact will be avoided.

_mg_3690The team from Mamaroneck High School introduced several innovative ideas with their design. To start, their design employed a super bright LED strip right before the crossing that would change colors from green to yellow to red as a train approached the crossing. This is a simple yet effective system because it is a universal system for drivers, rather than abstract signs and lights that are currently used. Their system also had an array of video cameras viewing the track from all sides so the train operator can view the crossing well before the train arrives there. In addition, their design used a system of lasers to detect if an obstruction was on the tracks. The lasers would detect when a car enters and exits a crossing, and whether the car is stuck on the tracks. In the case that a car is stuck on the tracks, the system will alert the train operator and MTA control. If the train is approaching and the obstruction hasn’t moved, their design incorporated a conveyor system that would physically move the car off the tracks.

_mg_3755The Mount Vernon team was just a single High School student due to a few no-shows on his team. What’s more is that the student did not have any prior experience with Arduino or electronics, yet he took on the challenge head on. His design incorporated simple ideas with tremendous effect. Firstly, his design incorporated extremely bright LEDs to light and indicate a crossing. Currently, crossings are not lit with any special lighting, they simply have the crossbucks sign. He also included a counter that would count down the time until a train arrived at the crossing. Finally, he included a pressure sensor that would alert the driver if there is a car on the tracks.

The judges were struck by the richness of the ideas and the degree to which the teens could implement them with the limited technology that we provided. Considering that they completed these designs in approximately 5 hours is a staggering achievement. In the end, the team from Putnam Valley High School took home the $500 prize, but each team left with prizes and a sense of fulfillment for not only completing this challenge but for creating designs that could potentially save lives.

The beauty of having high school students design these systems is that they have no preconceived notions of business, money, or government. They simply want to solve the problem. Each team showed incredible intelligence, focus, determination, and innovation and all of us at The DAE know that they are going to go on to do incredible things.
