Comparative analysis of vehicle speed on arterial roads with the greenshield model approach

Vehicle speed plays an important role in the traffic flow and road density. This parameter is often researched to obtain a model of the characteristics of an existing road section. This study aims to analyze vehicle speed on arterial roads using the Greenshield Model approach, which is a fundamental traffic model that describes the relationship between traffic density and vehicle speed. Through the collection of field data and statistical analysis, vehicle speed patterns and factors influencing them can be identified. The method used is t distribution analysis with the Greenshield Model approach to see the comparison of vehicle speed values on the Kenjeran highway and Kertajaya Indah road sections. The results show that the Greenshield Model can be effective in predicting traffic speeds on arterial roads, providing insights for better transportation planning and road design. Furthermore, the mathematical equation that can be produced on arterial roads is with an average speed value of 26.9 km/h and a standard error of 0.504 and an R2 correlation of 0.658. The conclusions of this study offer guidance for urban planners and transportation engineers in optimizing traffic flow and improving road user safety y=32.282 0.0347x.
