In this paper, we propose a service handoff scheme, termed as Safe-Passé, for provisioning Safety-as-a-Service (Safe-aaS) to the end-users in a $5G$ environment. A Safe-aaS architecture provides customized safety-related decisions to the end-users. Practically, the service region of a Safety Service Provider (SSP) is bounded. On the other hand, the distance for which the end-users request for services may cover the service region of multiple SSPs. As a result, the services provided to the end-users are interrupted due to switching from the service region of one SSP to another. However, none of the existing handoff schemes provide customized safety-related decisions to the end-users. Considering road transportation as the application scenario of Safe-aaS in a 5G-enabled Intelligent Transportation System (ITS) environment, we propose a service handoff scheme among the multiple service providers for provisioning safety-related decisions to the end-users. Based on the eminence and profit of a SSP to which the end-users have initially registered for services, we compute the profit of the nearest SSP, who agrees to provide services to that end-user. We map these interactions among the SSPs to a cooperative coalition game, where the SSPs act as players. Extensive simulation-based analysis demonstrates that the ratio of the end-users served to the total number of end-users is improved by 4.19% and 3.65% using Safe-Passé compared to the existing handoff schemes, UCH and VHO.
