This research aims to develop a reliable density estimation method for signalised arterials based on cumulative counts from upstream and downstream detectors. Although traffic density is a key variable for analyzing network performance, its estimation is still challenging due to counting errors associated with urban arterials with mid-link sinks and sources. In order to overcome the issue, CUmulative plots and Probe Integration for Travel timE estimation (CUPRITE) is employed for density estimation. CUPRITE reduces or cancels the counting inconsistencies when vehicles' conservation is not satisfied within a section by utilizing probe vehicles' samples. The method is tested in a controlled environment, and the authors demonstrate the effectiveness of CUPRITE for density estimation in a signalised section.
