Analysis of The Impact of The Imposition of Existing Tariffs on The Average Daily Traffic of The Krian – Legundi - Bunder Toll Road

Abstract

The imposition of toll tariffs on the Krian–Legundi–Bunder (KLB) Toll Road has resulted in suboptimal traffic volume, as the current rates do not align with the users’ Ability to Pay (ATP) and Willingness to Pay (WTP). This research aims to analyze how existing toll tariffs affect Average Daily Traffic (ADT), particularly focusing on users in Gresik Regency. A quantitative descriptive method was employed, involving traffic count surveys and roadside interviews (RSI) at strategic toll gates and arterial roads. Data were analyzed through stated preference models and regression equations to measure the probability of route choice changes. The findings reveal that higher toll rates significantly deter users from toll roads, whereas reducing the tariff to Rp. 650/km could shift approximately 1,808 vehicles/day from arterial roads to the toll road. The implications highlight the need for toll policy revisions that consider socio-economic conditions to ensure infrastructure utilization and financial sustainability. Future studies are encouraged to incorporate broader behavioral and demographic variables with real-time modeling to refine toll pricing strategies further.
