RAZVOJ I PROCENA PROTOTIPNOG SISTEMA SVETLOSNIH OZNAKA NA OGRADAMA
Journal Title: INTERNATIONAL JOURNAL FOR TRAFFIC AND TRANSPORT ENGINEERING - Year 2012, Vol 2, Issue 2
Abstract
Trenutno se na ogradama u zonama radova koriste standardna svetla upozorenja koja imaju funkcije usmeravanja i upozoravanja. Ova trepćuća žuta svetla u zonama radova danas se koriste u različite svrhe. Razvijeni su i procenjeni koncepti nestandardnih sistema svetlosne signalizacije na ogradama: trepćuća crvena svetla kada je u zoni radova saobraćaj zaustavljen ili veoma spor, trepćuća zelena svetla kada zona radova nije aktivna i kada se saobraćaj odvija normalno, žuta svetla koja se šire kada vozači treba da uspore i pojačaju pažnju, i putujuće žuto svetlo kada zatvaranje trake zahteva da se vozači pomere udesno ili ulevo. Projektovane su i proizvedene prototipne jedinice. Anketa među vozačima o razumevanju ovih funkcija prikazana u radu pokazala je da bi ih vozači verovatno sve razumeli, ali da trepćuće crvene i zelene funkcije mogu da izazovu konflikt u odnosu na druge uređaje za upravljanje saobraćajem na putu. Terenska procena o funkcijama svetala koja se šire ili putuju u zonama radova na maketi pokazala je da se način na koji vozači razumeju svetlosne signale može preneti i na stvarnu situaciju u vožnji. Reagujući na putujuću funkciju svetla vozači su se ranije prestrojavali (pri čemu je prostor za prestrojavanje u drugu traku bio za 40% duži) u odnosu na konvencionalno trepćuće svetlo na ogradama, dok su subjektivne procene o nameravanom značenju testiranih funkcija takođe bile pozitivne.
