The invention refers to an intelligent transport system (10) and a method for improving road safety. Further, the invention pertains to a method for a first road user (16) and a method for a second road user (20). Moreover, the invention relates to an electronic device (24) and to computer programs.It is provided that a detected event (18) by a road user (16) and/or a road infrastructure (14) is broadcasted to the environment via a direct communication signal including a cloud-upload-information indicating whether the event (18) has been uploaded to a backend server (12) or not. Based on the cloud-upload-information, surrounding road users (20, 22, 24) receiving the direct communication signals know whether an upload of the detected event (18) to the backend server (12) is required or not. Therefore, redundant uploads of the detected event (18) to the backend server (12) by other road users (20, 22, 24) which are connected to or connectable with the backend server (12) may be prevented.

Furthermore, the invention pertains to computer programs. It is provided that a detected event (18) by a first road user (16) and/or a road infrastructure (14) is broadcasted locally to the environment via direct communication signals and received by surrounding other road users (20). Road users (20) which are connected to or connectable with a backend server (12), upload the received information about the detected event (18) to the backend server (12). Then, other road users (22) not being in range of the broadcasted direct communication signal but connected to the backend server (12) can also be informed and/or warned of the detected event (18).
