 Figure 1: TransSec Vehicle to pedestrian (V2P) Mobile Application

TSSG is developing a mobile application to keep the pedestrians safe during intentional truck attacks. In recent years there are a lot of terrorist truck incidents that took place around the world. Terrorist uses a truck as a weapon to attack people walking on the streets. TSSG is working on an EU funded project TransSec; one of the tasks is to notify pedestrian regarding a potential threat. Alerts will be sent to mobile phones on the possible attacks and instruct them to evacuate to a safer place.

Whenever the truck incident takes place, the truck will broadcast to notify the TransSec server about the event. So, the TransSec server will publish a risk message with the payload (truck location, timestamps, etc.) to an MQTT broker. At the other end, mobile devices will subscribe to those messages and start extracting the data. Based on the data received, the application will calculate the distance to predict the risk and provide the evacuation routes.

The Service-Oriented Architecture (SOA) is followed for the mobile application and it is the publish-subscriber pattern. It would be a message-driven service which uses MQTT broker for communication between the end nodes.

TSSG’s researcher Dr. Ruisong Han is working on an evacuation algorithm which will provide the shortest path to evacuate away from incidents place. This will be used in the developed mobile application. Dr. Ruisong’s simulation work can be viewed here.

The evacuation algorithms are designed based on the knowledge of graph theory (such as the shortest path algorithms), mathematical programming and evolutionary algorithms. Specifically, road networks are modeled as graphs and an evacuation route with the least weights (length or travel time) should be calculated and assigned to an end-user. Optimization methods are used to ensure that the evacuation algorithms can reach the desired performance from a personal scale or a global scale. In short, the core idea of the research is maximumly utilizing the benefits of Vehicle-to-Everything (V2X) communication and optimization algorithms, to deliver more innovative and effective evacuation algorithms and applications to the ITS industry.

Note: Vehicle to pedestrian (V2P) demo of a fully developed application will take place early next year at WIT west campus, Carriganore.

Whenever the truck incident takes place, the truck will broadcast to notify the TransSec server about the event. So, the TransSec server will publish a risk message with the payload (truck location, timestamps, etc.) to an MQTT broker. At the other end, mobile devices will subscribe to those messages and start extracting the data. Based on the data received, the application will calculate the distance to predict the risk and provide the evacuation routes.
