MOSAik:D - M2M-based optimization of safety in road works sites

Background

In order to keep the existing road network running efficiently, maintenance works are necessary. Depending on the timely extend, these are carried out in the context of short term (STRWS) or long (LTRWS) term roadworks sites. In these kinds of roadworks sites, various types of safety barriers are used, including passive protective equipment (concrete guide walls) in long-term roadworks sites.

In the case of short-term roadworks sites, only traffic cones (daylight) or vertical panel (nighttime) are used to separate the traffic and work areas depending on the time of day. Due to the limited duration, it is not possible to provide passive protection by barriers. Consequently, maintenance personnel in STRWS are generally exposed to higher risks.

Goal

The MOSAik:D project aims at improving the protection of roadworks site personnel as well as increasing the safety for traffic in STRWS with the help of M2M-communication. By combining modern communication and localization methods, arriving vehicles shall be informed about persons in the immediate danger zone in the traffic area. Additionally, construction site personnel should also be warned of potential dangers from uncontrolled vehicles.

Realization

A prerequisite for the detection of dangerous situations is the highly precise positioning of STRWS borders on the closed lanes. State-of-the-art methods for highly precise positioning as well as communication technologies are used to determine the extension of the work site. This information can be transmitted to connected vehicles via Vehicle-2-X-communication. MOSAik:D will contribute to automated driving in the construction site area in addition to increasing safety for maintenance personnel and road users in STRWS by using automated detection of the STRWS equipment.

The University of Applied Sciences Erfurt is responsible for the following tasks in the progress of the project:

• Creation of a catalog of requirements and scenarios based on the results of preliminary investigations
• Detailed specification of the technical components with the result of a total system specification
• Development of a vehicle system
• Evaluation of the total system with regard to the fulfillment of the technical, functional and non-functional requirements
