Abstract EN
The real-time traffic signal control for intersection requires dynamic turning movements as the basic input data.
It is impossible to detect dynamic turning movements directly through current traffic surveillance systems, but dynamic origin-destination (O-D) estimation can obtain it.
However, the combined models of dynamic O-D estimation and real-time traffic signal control are rare in the literature.
A framework for the multiobjective traffic signal control model for intersection based on dynamic O-D estimation (MSC-DODE) is presented.
A state-space model using Kalman filtering is first formulated to estimate the dynamic turning movements; then a revised sequential Kalman filtering algorithm is designed to solve the model, and the root mean square error and mean percentage error are used to evaluate the accuracy of estimated dynamic turning proportions.
Furthermore, a multiobjective traffic signal control model is put forward to achieve real-time signal control parameters and evaluation indices.
Finally, based on practical survey data, the evaluation indices from MSC-DODE are compared with those from Webster method.
The actual and estimated turning movements are further input into MSC-DODE, respectively, and results are also compared.
Case studies show that results of MSC-DODE are better than those of Webster method and are very close to unavailable actual values.
