Abstract: The problem of accident is very acute in highway transportation due to complex flow patterns of vehicular traffic presence of mixed traffic and pedestrians. Traffic accidents may involve property damages, personal injuries or even causalities. One of the main objectives of traffic engineering is to provide safe traffic movements. Road accident cannot be totally prevented, but by suitable traffic engineering and management measure, the accident rate can be decreased considerably. Therefore to carry out systematic accident studies to investigate the causes of accidents and to take preventive measures in terms of design and control. To develop road accident prediction model each and every parameter related with the accident is considered and a micro level analysis of road accident is performed. For micro level analysis road accident data of last eleven year (2010 to 2019) from different five police station is collected and a detailed analysis is performed on basis like Hour, year, location, type of collision, type of road, physical feature of road, age group, sex etc. On basis of these analysis effect of accident is identified. After analysis road accident prediction models is developed based on different parameter like Number of Vehicle and population ratio and vehicular composition. All the models are validate through F test and Chi Square test. 2020-07-01T00:00:00Z http://10.9.150.37:8080/dspace//handle/atmiyauni/1302 Title: Impact Of Pavement Condition On Capacity And Level Of Service For Urban Road Authors: Khirasariya, Deepkumar Rasikbhai Abstract: The flexible pavement can be rated on the basis of different types of parameters which can be measured and worked upon to get the desired results. This study deals with the flexible pavement condition and its impact on capacity and LOS of urban road. In this study, evaluate the flexible pavement conditions to determine and specify the types of the distress parameter in the flexible pavement for the selected roads. The distress parameter are included cracking(%), raveling(%), potholes(%), shoving(%), patching(%), settlement and depression(%) and Rut depth(%). Rating of pavement have been done on the pavement condition assessment by using MoRTH (Guidelines Maintenance Management of Primary, Secondary and Urban Roads, IRC 2004) on selected urban roads, and evaluated traffic volume in terms of PCU/hr of a urban road and according to capacity find out the Level of Service (LOS) as per Indo HCM on urban road. 2021-10-01T00:00:00Z http://10.9.150.37:8080/dspace//handle/atmiyauni/1301 Title: A Study on Performance of Fly ash and Recycle Concrete Aggregate in DLC for Rigid Pavement Authors: Mavani, Neel Vinodbhai Abstract: Rigid pavements are constructed of Portland cement concrete slabs resting on a prepared sub base of granular material or directly on a granular sub grade. Load is transmitted through the slabs to the underlying sub grade by flexure of the slabs. There are Sub grade, sub base and base layer for Rigid pavement. Sub base is also known as the DLC layer. Dry Lean Concrete is a mixture in which the amount of cement is less than the amount of liquid that is present in the layers. It is smooth concrete with a large proportion of aggregate in relation to cement than conventional concrete and is generally used as a base/sub-base for hard paving. Although the actual thickness will be governed by the design considerations, a thickness of minimum 150 mm is recommended for all major projects of State Highways and National Highways. When DLC is adopted as sub base in case of roads other than the above road sits thickness of 100 mm is recommended. Increase the strength of DRY LEAN CONCRETE by using FA & RCA. To Compare to Economic analysis for DLC & DLC added materials of FA and RCA Study of bearing pressure revealed a good resistance of the granular mixture (recycled concrete aggregate + cement). It has been observed that by curing of blended RCA, it has gained very high strength which shows that with the addition of cement to blend of sand and RCA, it becomes semi- rigid pavement i.e the pavement changes its nature from flexible to semi-rigid pavement. In present study aims preparing concrete by adding materials of Ordinary Portland Cement (OPC) with fly ash 15% and RCA in various proportion like- 10%, 20%, 30%. By mass of quantity. Maximum compressive strength for DLC + FA (15%) and RCA 20%is 9.48 MPA. The study discloses that high volume of Fly Ash in concrete reduces the water demand and improves. Experiments such as compressive test. Economic analysis compare to DLC and DLC added by Fly ash and RCA. 2021-07-01T00:00:00Z http://10.9.150.37:8080/dspace//handle/atmiyauni/1300 Title: Estimation Of Dynamic Pcus Under Heterogeneous Traffic Condition On Urban Road: A Case Study Of Rajkot City Authors: Barad, Ami Dineshbhai Abstract: This study presents the concept of “Dynamic Passenger Car Unit (DPCU)” for the urban local roads under heterogeneous traffic condition, and it reflects that the Passenger Car Unit (PCU) is not a static factor as assumed. The parameter considered for the estimation of the DPCU are (1) average speed of vehicle (2) projected rectangular area of vehicle (3) length of vehicle. The traffic data was collected at the mid-block section as of the following roads: (1) Nana mava road (2) Raiya road. Both roads having same geometric condition. The mid-block section was kept of 30m and traffic data was collected. The roads are two lane divided roads and having different traffic composition. The mid-block section was such selected that it was free from parked vehicles, bus stop, effects of the intersection, curvatures etc. The DPCU was obtained by following two methods: (1) Homogenization coefficient method (2) Chandra’s method. The traffic data was collected using videography method for in morning 8:00am to 12:00pm and in evening 4:00pm to 8:00pm was concluded for the roads by the study of traffic volume. The peak hour traffic was used to calculate the DOCU values and efforts were made to suggest the best reliable DPCU value. 2021-01-01T00:00:00Z
