79. RECOMMENDATION
SIGNING:
ADVANCE STREET NAME SIGNS
(W16-8) ON INTERSECTION
WARNING SIGNS
RETRO REFLECTIVE SIGN POST
PANELS
SOLAR-POWERED, SIGN-MOUNTED
BEACONS
REPLACEMENT OF ADDITIONAL
SAFETY RELATED SIGNS (E.G., DO
NOT ENTER, ONE WAY, ETC.)
WITHIN 500 FEET OF THE
INTERSECTION
81. RECOMMENDATION
PEDESTRIAN:
INTEGRATE THE NEEDS OF PEDESTRIANS AT THE
EARLIEST STAGES OF URBAN PLANNING
PROJECTS AND TRANSPORT INVESTMENTS.
ESTABLISH CLEAR ADMINISTRATIVE
RESPONSIBILITIES AT ALL LEVELS OF
GOVERNMENT FOR COORDINATION OF
INITIATIVES TO PROMOTE WALKING.
IMPROVE KNOWLEDGE ABOUT WALKING.
DEVELOP CAR-FREE AREAS, DISCOURAGE OVERUSE OF CARS IN CITY CENTERS, AND PREVENT
PARKING ON PAVEMENTS AND PEDESTRIAN
CROSSINGS
signalling devices positioned at road intersections, pedestrian crossings and other locations to control competing flows of trafficPrimary signal: in approach , before crossing intersection , at right handSecondary signal: in approach , after crossing intersection , at right handTertiary signal: the hanging signal used for high speed road, where the driver can see the signal from a very far point . and there is no reason for using this in this street
