Analysis of dangers in the operation of city buses at the intersections

Summary Operation of motor vehicles should take into account the elimination of the possibility of accidents. The article considers selected problems occurring in the operation of public transport buses at intersections. Compliance with the requirements of the safety system during signal change on the signaling device controlling traffic at the intersection was analyzed. The human factor in ergonomics is important. Ending the green signal display (in special situations) causes a dilemma of decisions. The driver brakes abruptly (resulting in potentially harming passengers on the bus) or passes through a signal light displaying a red signal. The need to introduce changes in the regulations that would allow the introduction of adequate solutions was pointed out. These are activities in the area of the active safety system in the operation of vehicles in road traffic. The need to provide advance information and change the provisions in applicable law has been demonstrated.

Advance Information

Abstract Imprecise and defective regulations should be eliminated in the operation of vehicles. The article discusses and evaluates the differences in legal acts regarding the requirements for the yellow signal at intersections with traffic lights. Poland has signed the Vienna Convention on signs and signals. When implementing it into Polish legislation, the original provision was changed slightly. The reason for the ban on entering the intersection during the yellow signal has been changed. As a result, an unfavorable situation arises for the driver without a good way out. In addition, a colloquial word was introduced, undefined – “rapid braking”. The changes introduced in relation to the Vienna Convention were analyzed and evaluated. Defects were found and the need and necessity of correction of the applicable provision were reported. The necessity to consider changing the provision in the Vienna Convention was also pointed out. There is a need to provide advance information about an upcoming change. These are activities in the operation of vehicles in road traffic from the area of active safety system. It may be possible to use e.g. a flashing signal in the final phase of displaying a solid green signal on the S1 signaling device for vehicles.

Lack Of Knowledge

Abstract The article presents and assesses the shortcomings of the applicable provisions regarding the maintenance of the necessary distance behind the preceding vehicle in road traffic. We are exposed to accidents when using vehicles. The human factor contributes greatly to their occurrence. A problem analysis was carried out with proposed changes. The conclusions indicate the need for conducting training and clarification of the provisions in the applicable road traffic law. The introduction of new technical devices for determining the distance, in extreme situations, does not eliminate the danger of colliding with the preceding vehicle. In this respect, the regulations are imprecise, and the lack of knowledge of drivers is huge. The proposed actions relate to the area of active safety system of vehicles in road traffic.
