| Due to the growth of traffic has risen sharply, the construction of road traffic facilitiesand public transportation management fall behind. It brings a lot of traffic problems.Especially the management of bus safety far lags behind traffic growth, rate of traffic accidentis increasing.It caused huge economic losses to. In view of the above situation, we research Xi’an sixth bus companies, and developed appropriate bus driver’s dynamic supervision systemcombined with the actual situation. The main research contents and results are as follows:1. The three typical unsafe driving behavior of the bus drivers are determined based onthe basis of full investigation, and they are speeding, the distance between two cars is tooclose, improper control of the door switch.2. In order to for the bus speed for dynamic supervision, based on the basic road speedmodel based on the analysis of the applicability, the introduction of bus flow parameters suchas proportion, bus, establish an improved hybrid vehicle running speed model, selection ofunidirectional lane traffic test investigation, and uses Matlab to improve the model parametercalibration, bus speed model is established, and a speed control system is designed to monitorthe bus current speed is safe.3. A car door control system is designed, it protect passengers through identifying thespeed whether the current situation is appropriate to switch the door operation. The systemhas provided the security for passengers.4. The system identify license plate by using a CCD camera, and determine the distancebetween two cars through proportion of license plate and pictures. It determines whether thecurrent car is security, and it warn the drivers when necessary. |
