The Ahmedabad–Vadodara Expressway (NE-1) is one of Gujarat’s most important roadways, offering fast and direct connectivity between two of the state’s major cities. Although the expressway was constructed with modern engineering standards and safety features, a troubling pattern of traffic accidents has emerged over the past several years. This research investigates crash occurrences on NE-1 between 2017 and 2024, with the aim of identifying sections of the roadway that pose higher risk to travelers — commonly referred to as blackspots. The analysis draws on accident reports filed at local police stations and traffic volume records collected from toll booths along the corridor. Several evaluation methods were applied, including the Weighted Severity Index (WSI), Severity Index (SI), Average Annual Total Crash (AATC), Accident Severity Index (ASI), and GIS-based heatmap analysis. From this assessment, thirteen distinct blackspot locations were pinpointed. Contributing factors behind these incidents ranged from over-speeding and tyre blowouts to driver exhaustion, poor adherence to lane discipline, and unregulated vehicle entries. In response to these findings, the study proposes a series of targeted interventions that align with IRC: SP:131-2022 guidelines. These include road geometry improvements, speed management, better signage, measures to control stray animals, and initiatives aimed at educating drivers. The recommendations are intended to significantly reduce the severity and frequency of accidents across the NE-1 route.
