Study of the ınfluence of coordınated regulatıon on the traffıc flow parameters on ıntersectıng streets

Fuad Dashdamirov Turan Verdiyev

The article studies the nature of changes in traffic flow parameters on the intersecting streets when using coordinated regulation to organize uninterrupted traffic on city highways. The influence of the "green  wave"  mode  on  the  traffic  flow  parameters  is analyzed.  Traffic  delays  on intersecting  streets were compared before and after the implementation of coordinated regulation. Traffic delay values at intersections were determined and analyzed in a comparative manner using the Webster and HCM 2010 methodology  and  simulation  tests.  Measurements  were  carried  out  based  on  real  values  (speed  and traffic  intensity  on  sections)  taken  at  7  intersections  of  the  street  network  of  the  city  of  Baku.  For simulation tests, a coordinated regulation model built in the PTVVISSIM program was used. Using the created micromodel, the results of the impact of the implementation of coordinated regulation on traffic delays on main and intersecting streets were tested. The total time losses on the street where the "green wave" is implemented and on intersecting streets were estimated for the options before and after  the coordination of traffic light modes. Based on the values determined by all three methods, it was found that  after  the  implementation  of  coordinated  regulation  on  the  main street the  delay time  of  vehicles increases  on  intersecting  streets.  The  proposed  approach  can  help  to  evaluate  the  effectiveness  of coordinated regulation in terms of time losses before its implementation on city streets
