Safety-Potential-Based Black Spot Safety Management Approach: A Case Study in Ho Chi Minh City

Black Spot Safety Management (BSM) employs identification and treatment of black spots as the two basic stages. Traditionally, these two stages base themselves mainly on recorded accidents rather than safety potential (SAPO). This paper intends to introduce an innovative BSM approach called SAPO-Based BSM which developed is based on the Network Safety Management (BASt & Setra, 2005). There are two basic stages in this approach: SAPO calculation and accident pattern analysis. The innovation lies in the fact that SAPO-Based BSM approach takes SAPO as the main indicator of black spots; and SAPO is determined by means of the traffic volume and the severity of accidents. In order to illustrate the effectiveness of SAPO-Based BSM approach, this paper provides an empirical investigation in which SAPO-Based BSM is practically applied to the local road traffic situations in Ho Chi Minh City (HCMC).
