Precise identification of black spots can ensure the timely adoption of remedial measures to mitigate road accidents. The review of various trends of approaches towards identifying the black spots by studying the evolved-up techniques towards a pre-emptive investigation of crash events is the focus of the paper. This study contributes to briefing all the open research issues that existing researchers have merely explored. The paper also discusses addressing such open-end problems that offer more edge to the precise analysis of black spots, followed by a possible plan towards solving these issues to mitigate blackspots.
