Vaghani ?ABSTRACT Rotary intersections or round about are special form of at-grade intersections laid out for the movement of traffic in one direction around a central traffic island. Essentially all the major conflicts at an intersection namely the collision between through and right-turn movements are converted into milder conflicts namely merging and diverging. The vehicles entering the rotary are gently forced to move in a clockwise direction in orderly fashion. They then weave out of the rotary to the desired direction. .A present scenario of traffic is, Traffic is increased day by day and it was impossible to control to traffic at major intersection by traffic police manually.

One way to controlled traffic at major or busy intersection is to construct a rotary, which is special type at grade intersection. Where all converging vehicle are forced to move around a central island in clock wise direction. The intersection has for approach road with one way traffic in all approach road and there is no traffic police, signals to controlled traffic for 24 hours .Design of rotary in this way major conflict are converted in to major or minor conflict like merging or diverging and vehicle entering the rotary are gently forced to move in clock wise direction .And accidents will be minimum to say nearly zero for this essential to have the information on traffic volume coming from approach road 1. INTRODUCTION1.

1 GENERAL Rotary intersections or round about are special form of at-grade intersections laid out for the movement of traffic in one direction around a central traffic island. Essentially all the major conflicts at an intersection namely the collision between through and right-turn movements are converted into milder conflicts namely merging and diverging. The vehicles entering the rotary are gently forced to move in a clockwise direction in orderly fashion.

They then weave out of the rotary to the desired direction. Traffic congestion has a number of negative effects:? Wasting time of motorists and passengers (“opportunity cost”). As a non-productive activity for most people, congestion reduces regional economic health.? Delays, which may result in late arrival for employment, meetings, and education, resulting in lost business, disciplinary action or other personal losses.? Inability to forecast travel time accurately, leading to drivers allocating more time to travel “just in case”, and less time on productive activities.? Wasted fuel increasing air pollution and carbon dioxide emissions owing to increased idling, acceleration and braking.? Wear and tear on vehicles as a result of idling in traffic and frequent acceleration and braking, leading to more frequent repairs and replacements.? Stressed and frustrated motorists, encouraging road rage and reduced health of motorists? Emergencies: blocked traffic may interfere with the passage of emergency vehicles traveling to their destinations where they are urgently needed.? Spill over effect from congested main arteries to secondary roads and side streets as alternative routes are attempted (‘rat running’), which may affect neighbourhood amenity and real estate prices.? Higher chance of collisions due to tight spacing and constant stopping-and-going.1.2 AIM: To design a rotary ( 4T ) which will reduced accidents,conflift point and delay as well as increse safety and confort of road user.1.3 OBJECTIVE: o To study existing traffic condition.o To identify traffic problems at intersection o To conduct traffic volume count o To minimise the conflict point at intersectiono Find solution to overcome traffic problem
