New Radio (NR) Vehicle-to-Everything (V2X) based Vulnerable Road User Protection (VRUP) can effectively reduce traffic accidents, making it a promising application in intelligent transport systems. However, considering the scarcity of radio resources and inefficiency resource allocation, performance reduction caused by collisions may restrict its development V2X network. In this paper, we propose flexible allocation scheme, namely Zone cluster Resource Reuse (ZRR), to collision achieve better delivery NR VRUP. We then develop theoretical framework on stochastic geometry efficiently characterize VRUP message process under ZRR, taking into account specified factors V2X. With help framework, are able derive two important metrics, probability Equipment (UE) transmit power, further search for optimal parameter setting ZRR. Extensive simulation results provided demonstrate effectiveness ZRR framework. Under setting, is very desirable delivery, especially resource-constrained access-intensive scenario.
