Sensus is a vehicle-to-vehicle communication system that offers different modes of transportation a way to speak to one another as a means of ensuring awareness and safety on the roads.

As we have all experienced, congestion and safety concerns are unavoidable problems that result when traveling in dense, urban environments. To alleviate this issue, my team and I were inspired to learn about the transportation infrastructure and deliver a solution that could ensure and sustain safety for all modes of transportation on the road.
Based on our discovery research, it was reported that 53% of on-road collisions occur at broadside or intersections. Travelers are either undetected or unaware of each other’s location in these tight corners, especially for the car driver. Blind spot zones of a car are larger than one can perceive, and have thus caused major problems for drivers and the surrounding modes of transportation.
― User Needs
Thirty-eight user interviews (15 car owners and 23 cyclists, pedestrians, etc.) were conducted in urban locations like NYC and Providence to get a better perspective as to how our users are impacted by the current problems that occur causing on-road collisions. We asked questions discussing relevant concerns and possible solutions that would help in improving the transport experience between vehicles and other modes of transportation.

― Concept Exploration
After synthesizing the user research, we deduced that physical awareness between modes of transportation would help resolve safety and liability issues on the road. Upon diverging and converging on numerous concepts for our product, we gauged which ones to move forward with based on these criteria: feasibility, desirability, and viability. Once our team narrowed down to four concepts, we asked our users which idea best suited their needs, and documented their feedback through colored dots.
― System Design
We researched numerous technologies and products that could provide the location-tracking capabilities Sensus needs to give our users better awareness of surrounding travelers. This effort led us to design the Sensus Network System.
Upon doing extensive user interviews, we created two personas that best represented the 38 users we researched: car drivers and non-car owners (ie cyclists, pedestrians, etc.)

This user would wear or carry the Sensus movement tracker so that vehicles on the road can detect the 5.9GHz band that is emitted by the tracker.
They would also have the Sensus app available to them, which features three major functions: map, accident protocol and the history log. These three features are designed to help commuters travel from place to place, record any accidents, as well as search for nearby attractions or features that assist in improving their travel experience.
-- car owners
-- truck drivers
-- taxi drivers
For the car user, he or she would use the Sensus dashboard app to track on-road travelers. This dashboard app performs similarly to that of the mobile app service in featuring the map, accident protocol and the history log functionality. It also utilizes the vehicle’s built-in audio and display system to present visual and audible indicators when alerting a car driver of surrounding on-road parties once the V2V communication technology has detected their 5.9 GHz signal.
Sensus strives to be a unified system that encourages all travelers to be more responsible and aware on the road in order to ensure a safer and engaging traveling experience.
