Development of Assessment Tools for Road Safety Performance during Execution of National Road Project Improvement in Bali-Indonesia

Bali's economy dominantly grew from the tourism sector's revenue, while tourism growth depends on availability of accessibility Road infrastructure as a means of accessibility is expected to deliver a steady level of road inspection. In order to provide a steady service, the road infrastructure condition required maintenance. However, the phenomenon during road maintenance execution always has a negative impact. Negative impacts posed in road work zones include congestion, noise, accidents and air pollution. Implementation of road safety performance of work zone inadequate and frequent highlights of road users is studied in this paper. The weighting of safety attributes performance is designed using the Analytical Hierarchy Process (AHP) method. Scoring for the implementations and performance scales using Likert scales. The result of identification found 4 zone in the road work zone consist of area into work zone, initial taper zone, work zone and end taper zone with a weight of 27%, 9%, 59% and 6% respectively. Design of assessment of performance of safety in a work zone is applied to execute West Gatot Subroto link road as National road improvement project fiscal year 2017 in Bali province, Indonesia. The road safety performance is found in good performance category (scale 3.6).
