Abstract
Increased accidents on Ugandan roads compelled the construction of road ancillaries, with a major aim of improving road safety, to attain sustainable economic development and further achieve SDG target 3.6 and SDG target 9.1. This study investigated the impact of ancillary roadworks on road safety in Uganda, a case of the Kampala – Jinja road. The study used a correlation research design with a quantitative approach. Primary data were collected from 30 field traffic officers, 19 drivers, 03 OC traffic police stations, 36 road engineers, 01 IOV, 01 RTO, and 12 market leaders whereas secondary data were extracted from accident data from Uganda Police. Questionnaire data were analysed with SPSS version 24.0. Results indicated that 39% of installed informatory signs, 47% of installed regulatory signs, and 60% of installed warning signs had been vandalised, exposing road users to the risk of accidents. Guardrails were still existing but some had rusted and others covered with grown grass, making them not seen by road users. The majority of road accidents were serious, accounting for 149 (46.3%) cases, followed by 130 fatal accidents (40.4%) and 43 (13.3%) minor accidents for the period from 2017 to 2022. Correlation results indicated that all ancillary road works were significant except road signs. Yet, regression results indicated that road marking (βeta = 0.307), guardrails (βeta = 0.286), and humps and rumble strips (βeta = 0.360) have a positive significant effect on road safety unlike road lights, road signs, walkways, and service lanes which were insignificant. Police traffic law enforcement and regular improvement on road infrastructure are required. It is concluded that road marking, guardrails, humps, and rumble strips significantly affect road safety. The study recommended that the construction of humps and rumble strips of moderate size, road marking with higher retro reflectivity (>200 mcd/lx/m2), and strong guardrails, can help in ensuring road safety with the support of enforcement of traffic laws of Uganda.
