| contents | This paper introduces a novel intention-sharing mechanism for Electrically Power-Assisted Cycles (EPACs) within V2X communication frameworks, enhancing the ETSI VRU Awareness Message (VAM) protocol. The method replaces discrete predicted trajectory points with a compact elliptical geographical area representation derived via quadratic polynomial fitting and Least Squares Method (LSM). This approach encodes trajectory predictions with fixed-size data payloads, independent of the number of forecasted points, enabling higher-frequency transmissions and improved network reliability. Simulation results demonstrate superior inter-packet gap (IPG) performance compared to standard ETSI VAMs, particularly under constrained communication conditions. A physical experiment validates the feasibility of real-time deployment on embedded systems. The method supports scalable, low-latency intention sharing, contributing to cooperative perception and enhanced safety for vulnerable road users in connected and automated mobility ecosystems. Finally, we discuss the viability of LSM and open the door to other methods for prediction. |
