The paper is focused on the evaluation and comparison of driving dynamics of the intervention of the first-exit fire truck type water tender at units of the Fire Rescue Service of the Czech Republic in the Moravian-Silesian Region. The aim of the comparison is to specify different driving characteristics both in the center of the Ostrava urban agglomeration, Fifejdy city part, and in the district town Nový Jičín. Professional telemetry, which was placed in the monitored vehicles, was used to obtain primary records of the driving behavior of emergency fire-fighting vehicles. These records were then evaluated with the telemetry supplier’s company software. Our findings should be reflected in the future calculations of driving times and the area coverage.
Vyhodnocení reálných záznamů jízdy k zásahům z pohledu dynamiky jízdy

The paper briefly informs about the content, solution procedures, and selected results of the student grant competition project entitled “Verification of driving characteristics of firefighting vehicles of type water tender” (Id. No. SP2021/58). It summarizes the results of one of the two main project objectives, which is an evaluation of the emergency driving records of selected emergency firefighting vehicles of the type of water tenders with a focus on driving dynamics.
Vyhodnocení součinitele adheze vybraných pneumatik pro zásahový požární automobil

The paper summarizes the results of testing and evaluation of the suitability of three selected types of tires for emergency fire trucks at units of the Fire and Rescue Service of the Czech Republic. The testing focused on determining the coefficient of adhesion in the longitudinal and lateral directions of the vehicle. In the longitudinal direction, data were obtained during braking manoeuvres. The actual braking distances and stopping times were measured. From these data, a braking deceleration and a theoretical coefficient of adhesion were calculated by a company's software. To determine the operating acceleration values in the lateral direction, measurements were made on a circular track with three given internal radii. The results of the measurements were used as one of the bases for determining a methodical procedure for performing tests of the functional tire properties for emergency fire trucks, especially water tenders, used by the Fire and Rescue Service of the Czech Republic.
