Description: a { text-decoration: none; color: #464feb; } tr th, tr td { border: 1px solid #e6e6e6; } tr th { background-color: #f5f5f5; }The RoadsAccidentHazard_LocalMunics_KZN layer quantifies the relative accident hazard associated with road infrastructure within KwaZulu‑Natal local municipalities.Road segments were first classified by type and assigned weights (Rank 1–10) based on their expected contribution to accident risk:10 – National Freeway: High‑speed long‑distance movement9 – National Road: Strategic inter‑city/provincial mobility8 – Interchange: Major junctions7 – On/Off Ramp: Freeway access points6 – Arterial Road: High‑volume urban/suburban corridors5 – Main Road4 – Secondary Road3 – Street2 – Other Road: Unclassified/minor access routes1 – Footpath: Pedestrian movement onlyThese weights were integrated with slope and weather‑risk inputs to adjust likelihood of road‑related accidents (e.g., steep gradients, rainfall‑related conditions).
