Accidental Survey of Different Intersection of Junagadh City

Abstract

Intersections are known to be high-risk areas for traffic accidents due to the convergence of different streams of traffic. By conducting an accidental survey, identify patterns and common causes of accidents. This study attempts investigation and analysis to prevent accidents at intersection which have high number of accidents. To get an insight into the trend of road accidents we collect last 3 years of accident data of different intersection of Junagadh city from District Traffic Office of Junagadh by taking permission from SP office Junagadh. And selected intersection is “Majevadi gate” Because in last 3 years, maximum number of accidents have occurred at this intersection. To reduce accidents at this intersection, we design a rotary intersection at the Intersection.

Introduction

I. INTRODUCTION

Road Network is the heart of a nation and transport services are considered as growth engines of the country. The increasing number of vehicles on the roads across the world has made the issue of congestion and accidents. Therefore, prevention and control of accidents has become the necessary. Intersections are known to be high-risk areas for traffic accidents due to the convergence of different streams of traffic. Road intersections play a crucial role in transportation systems as they facilitate the movement of vehicles and pedestrians. Analysing road intersections is essential for understanding their efficiency, safety, and overall performance. In order to deal with the traffic safety and vehicle safety of intersections, it is necessary to analyse the accident data in the intersection.

A. Need to study

Increased traffic volumes, infrastructure, and evolving urban dynamics have led to congestion, potential safety hazards, and inefficiencies at this intersection. To address these issues, research are needed to analyse accident data, assess safety conditions, and identify development opportunities.

B. Study Area

The Intersections I have selected is “Majevadi Gate” in Junagadh. Because in last 3 years, maximum number of accidents have occurred at this intersection.

II. OBJECTIVES

Following are the important objectives:-

1. Improved road safety, traffic management, urban planning, and overall transportation system effectiveness
2. Reducing accidents at intersections results in lower healthcare costs, vehicle repair expenses, and congestion-related losses. Survey-based interventions can lead to substantial economic benefits
3. Rotary Island help to reduce congestion and delays by keeping traffic moving in a circular motion instead of stopping at traditional intersections.
4. Rotary Island have been shown to be safer than traditional intersections
5. In Rotary Island by continuous traffic moving, they reduce the amount of time that vehicles are idling, which can lower emissions and improve air quality

III. DATA ANALYSIS

To collect accident data, first of all I take permission letter from the college. And visit all the police divisions for accident data but I did not get any data from all division they says we have no right share any accident data.

So, I go to SP office Junagadh and request for accident data for my research, He will give me permission and suggest to get accident data from Junagadh District Traffic Office. Therefore, I go to the District Traffic Office of Junagadh with the permission of the SP office. I tell him, I want accident data of time of accident, vehicles involved, location and cause of accident etc. They ask me to give them me some time to collect accidental data as per my requirement After half a month they called me to collect accident data in hard copy from District Traffic Office Junagadh.

A. Analysis of different timing of Accidents

In Morning rush hour from 7am to 9am during this time may lead to an increased number of accidents due to heavy traffic and rushed drivers.

In Evening rush hour from 4pm to 6pm Similar to the morning rush, evening rush hour sees increased traffic and potentially tired or impatient drivers.

In Late Night from 10pm to 2am Fatigue, reduced visibility, and potential alcohol consumption may contribute to a higher risk of accidents during these hours.

B. Analysis of Various Reasons of Accidents

Accidents can occur for various reasons, and analysing these reasons is crucial for developing effective preventive measures. Here's an analysis of different factors contributing to accidents:

Analysis of Different Vehicles of Accidents are given below

IV. DESIGN OF ROTARY ISLAND

It may be described as an enlarged road intersection, where all entering vehicles can find suitable gaps to move around an island in one direction before they can "Weave" out of the traffic flow into their respective directions radiating from the island. With rapid growth of traffic it is experienced that widening of roads and providing flyovers have become imperative to overcome major conflicts at intersections such as collision between through and right-turn movements. In this way, major conflicts are converted into milder conflicts like merging and diverging. The vehicles entering the rotary are gently forced to move in a clockwise direction. They then weave out of the rotary to the desired direction.

A. IRC Guidelines For Selecting Rotary Intersection

Because of the above limitation, rotaries are not suitable for every location. There are few guidelines that help in deciding the suitability of a rotary. They are listed below

1. Lowest traffic volume for which rotary treatment should be considered is about 500 veh/hr.
2. The maximum volume, that a traffic rotary can efficiently handle, can be taken as 3000 veh/hr. entering from all intersection legs.
3. A rotary is advantageous at locations where the proportion of right turning traffic is high.
4. A rotary is preferable if there are other junctions so near, that there would be insufficient space for the formation of queues

B. Design speed

All the vehicles are required to reduce their speed at a rotary. Therefore, the design speed of a rotary will reduction, the geometry may lead to very large size incurring huge cost of construction. The normal practice is to keep the design speed as 30 and 40 KMPH for urban and rural areas respectively.

For Urban areas, V=30 Kmph

C. Shape of Central Island

The shape and disposition of central island depend upon various factors such the number and disposition of intersecting roads and traffic flow pattern. The conditions under which a particular shape is favoured are discussed below table:

 [Table 4.3.1 - Conditions under which a particular shape ]
