Abstract
In order to enhance the midblock crossing safety of pedestrians at special locations, such as entrance of schools, hospitals, and supermarkets, the actuated signal control system is proposed to provide the special signal for vulnerable pedestrians’ crossing behavior, especially for the peak hours. Pressure sensors and inductive loops are applied to detect the number of pedestrians and the volume of approaching vehicles, and system function principle is designed to improve the efficiency and accuracy of signal control with a signal timing model. A roadway segment near Cuihua Road School is chosen as an example and the corresponding signal timing model is calibrated according to the geometrics of Cuihua Road. The layouts of detectors and facilities are allocated to protect pedestrians’ crossing at midblock crossings. The analysis result shows the efficiency of this method.
