Problem. The article considers the issue of determining the location of "bottlenecks" on the
highways of large cities based on the study of the vehicle's driving mode, obtained as a result of GPS
data processing and analysis. Purpose. The purpose of this study is to develop and test the methodology
for identifying potential "bottlenecks" on the city's freeway by analyzing the GPS track data of the car.
The subject of the study is the interrelationship of the characteristics of the sections of the city’s street road network (SRN) with the parameters characterizing the vehicle movement mode in the traffic flow.
Methodology. Two experimental routes with the same starting and ending points were chosen to obtain
data on traffic conditions on the SRN of the city of Kharkiv, which correspond to typical routes of official
movement of personal transport on weekdays. During the movement of the car along the specified
routes, GPS tracks were obtained, whose processing made it possible to determine the driving condi tions along the entire length of the routes. Results. The work presents a method of researching the
vehicle's driving mode by analyzing GPS track data; the determined indicators of the traffic regime,
which can be effectively used as criteria for determining potential "bottlenecks" on the city's SRN; the
methodology was tested on real traffic routes on the SRN of the city of Kharkiv. For selected routes, the
work presents histograms of instantaneous speed distribution, graphs of car movement in "distance -
speed" and "time - speed" coordinates. Graphs of changes in specific time in motion, specific idle time,
speed gradient, energy gradient, Hermann-Prygozhin criterion were obtained for individual kilometer
segments of routes. The specific idle time and the Herman-Prygozhin criterion turned out to be the most
effective criteria for the purposes of determining the "bottlenecks" of SRN. Originality. An experimental
technique was developed and tested, which allows to determine the potential "bottlenecks" of the city's
SRN as a result of conducting short-term and not labor-intensive research. The proposed approach does
not require the presence of specialized equipment or software, which makes this method effective when
conducting scientific research. Practical value. The possibility of using the proposed method of data
processing of GPS tracks to analyze traffic conditions on the city highway and identify potential "bot tlenecks" was shown. For the selected routes in Kharkiv, such sections turned out to be Vesnina St.
(beyond the intersection with Pushkinska St.); Heroes of Stalingrad Ave. (access to the intersection from
Leva Landau Ave.); Gagarina Ave. (access to the intersection with Kashtanova St.)
