Laboratory tests were performed using the WMA mixes and the conventional hot mix asphalt (HMA) as a reference prior to implementation at the sites. The WMA mixes were laid at 2 different locations (i.e. along a major road and in a road tunnel) in Singapore. The performance of the WMA mixes was assessed by conducting temperature measurements during laying operations and monitored through visual inspections and by measuring riding quality of the road in terms of International Roughness Index. From the laboratory results, it was observed that the WMA mixes provided similar results as compared with the conventional HMA. From the field implementations, it was noted that the WMA mixes produced similar workability as compared to HMA. In addition, it was observed that WMA can be compacted at the lower temperature of approximately 110 ˚C.","PeriodicalId":446196,"journal":{"name":"Journal of Society for Transportation and Traffic Studies","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129542353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Expressways are the highest class of roads in the Indian Road Network. India’s progress in the road sector measure 600 km of expressways approximately  and  is  planning  for  achieving  more  than  15000km  of  expressway  by  2021. Expressways are a controlled-access highway designed for fast traffic, with controlled entrance and exit. Expressways are vastly different from other roads of the country as vehicles such as bicycles, two-wheelers, three-wheelers and bullock carts are not allowed on these roads and additionally, there is no strict lane discipline. A number of research papers are available on studies on traffic stream characteristics for various roadway and traffic conditions. However, very limited studies are carried out on expressways in India  Video graphic data collection is widely used in traffic engineering, as video recordings can act as a more detailed, complete, accurate and reliable observational technique. To figure out the exact relationship between the traffic parameters, lots of research has been done over the past. Many attempts have been made earlier for data retrieval from videos. But, there have been very few attempts to discuss the methodology for data extraction and analysis from video for expressway data in India. This paper discusses about video graphic data collection, extraction and analysis of traffic stream characteristics for a duration of 8 hours by taking Ahmedabad -Vadodara expressway (four lane divided carriage way) as a case study. Data has been collected using video graphic survey by fixing high resolution cameras on road over bridge (ROB) such that traffic flow faces the camera.  Data on traffic volume, vehicle composition, speed of different vehicle categories, lane utilization etc. are manually extracted from the recorded video after converting it into frames. Data extraction and analysis has been done with the help of the softwares such as Ulead Video Studio, Irfan View and SPSS,  MS  Excel.  The  analysis  on  degree  of  lane  discipline  showed  that,  97%  of  vehicles  are following lanes. The results also showed that median side lane had high speed traffic as compared to other lane, which may be due to very high car composition (90%).","PeriodicalId":446196,"journal":{"name":"Journal of Society for Transportation and Traffic Studies","volume":"746 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133517683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The background layer contains all objects which have been stationary since the beginning of the video sequence. The foreground layer contains objects which have entered into or move within the video scene and these objects can be moving or stationary. An improved and adaptive Mixture of Gaussian (MoG) model with a feedback mechanism algorithm has been formulated. The MoG model will classify every pixel in the image as belonging either the foreground or the background layer. Every object in the foreground layer will be tracked and updated in the MoG via the feedback mechanism. This feedback avoids stationary foreground objects being updated into the MoG and thus affecting the approximation done by the MoG. This algorithm has been implemented into an Intelligent Transportation System (ITS) to detect vehicles on the road in an outdoor environment. A promising result is obtained in extracting vehicles on the road.","PeriodicalId":446196,"journal":{"name":"Journal of Society for Transportation and Traffic Studies","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123486025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presence of inundation has adverse effect on road infrastructure, especially on coastal arterial roads, which most of them made of mixture with conventional asphalt. To overcome this problem, it was proposed to use polymer modified asphalt (PMA) for the mixture. This study was carried out to evaluate the durability of the mixture with PMA that continuously immersed in the tidal water, to simulate the occurrence of some road infrastructure in Semarang which was inundated after tidal events. For this purpose, five immersion periods and three kinds of tidal  inundation  were selected. To evaluate the durability of the mixtures after immersion, two durability indices were used. The results showed that the water pressure (during immersion) could be one of the main causes of strength loss of the mixtures; however, if the water consists of certain chemical compound at sufficient amount, it could also contribute in reducing greatly the durability of the mixture.","PeriodicalId":446196,"journal":{"name":"Journal of Society for Transportation and Traffic Studies","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121083478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Motorcycle is promising for women’s travel but it is also causing driving difficulties that potentially cause accidents, while public transport and paratransit may be less safe. Accordingly, there is a possibility that women use motorcycle as an alternative safety travel. This study attempts to clarify the influence of gender on households’ decisions about vehicle ownership and usage, and to examine the gender differences in motorcycle usage. This study use a questionnaire survey data collected in JABODETABEK area in January 2010. An aggregate analysis was applied and an ordered probit model was developed to capture the impacts of satisfaction level towards paratransit on motorcycle usage. The hypothesis is women who don’t satisfy with the safety of paratransit tend to use motorcycle. The empirical results are: the lower satisfaction for Ojek security has a negative impact on their motorcycle usage for shopping activities.","PeriodicalId":446196,"journal":{"name":"Journal of Society for Transportation and Traffic Studies","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133969698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Decision makers are required to select a single maintenance strategy which closely meets their objectives and selection criteria. The set of criteria may  involve  economic  as  well  as  environmental  aspects,  some  of  which  may  not  be  easily quantifiable, thus requiring the use of qualitative judgments. Ranking approaches assign priorities to either distresses or maintenance treatments, and arrive at a maintenance program based on a selected set of criteria or preferences. A commonly used technique, in operations research, for prioritization of alternatives is known as Analytic Hierarchy Process (AHP). Its ability to embrace both quantitative and qualitative data through assignment of numerical values to qualitative data, and the significance of its role as a decision making tool for building a targeted model makes this the preferred method for prioritization. Therefore, this study explores the use of analytic hierarchy process (AHP) for prioritization of pavement rehabilitation treatments involving multiple criteria such as treatment cost, serviceability, and environmental implications. A Hypothetical numerical example is presented to illustrate the proposed framework for prioritizing 5 pavement rehabilitation techniques, namely, cold in-place (CIR), hot in-place (HIR) surfacing, hot in-place repaving, hot in-place remixing, and hot mix asphalt (HMA) overlay.","PeriodicalId":446196,"journal":{"name":"Journal of Society for Transportation and Traffic Studies","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129588852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of CBP is a common sight in most of the developing countries due to its economic adaptability. Although it has emerged as a cost- effective paving material, it is yet being developed as a full-fledged construction technique. The aim of this research was to develop a finite element model for CBP and evaluate the deflections in pavement with the application of loads. A three-dimensional finite element model was built to measure the elastic deflection basin with ANSYS finite element modelling software. The reason for developing a finite element model is, as the construction of concrete block pavements for experimenting is costly and challenging, a finite element model simulating the field conditions could be used to overcome these issues and perform further research. Previously developed finite element models and laboratory models were studied. The results obtained from the developed finite element model were verified with the deflection values obtained in a laboratory scaled model. Similar deflection basins could be observed for different load cases.

Warm mix asphalt (WMA) is identified as one of the alternative to the typical hot mix asphalt (HMA) used on pavement construction to reduce these emissions. WMA technology allows an asphalt mix to be prepared and placed at lower temperatures than conventional hot mix. This study is focused on a comparative study of three WMA mixes and a HMA control mix used in the construction of an environmentally focused subdivision in the City of Calgary, Alberta, Canada. The scope of the study covers aspects related to asphalt plant production, asphalt plant emissions, construction, laboratory performance, and initial road performance with different WMA technologies in comparison to HMA. Paper reports on the findings related to the asphalt plant production, asphalt plant emissions, and construction stage of the study. The advantages of using WMA technology were evidenced during the mix manufacturing and road construction stages. The WMA mixes showed reduced emissions, lower fuel consumption, reduced smoke and odors, improved safety and working environment, improved mix workability, extended compaction time, more uniform compaction, and reduced thermal segregation. The laboratory evaluation showed that the WMA mixes behaved similar or superior to the HMA mixes. WMA mixes had similar rutting and fatigue resistance, better low temperature behavior, higher laboratory workability, and similar stripping susceptibility, than the conventional HMA mixes. However WMA mixes showed slightly lower mix stiffness at high temperature compared to HMA mixes.","PeriodicalId":446196,"journal":{"name":"Journal of Society for Transportation and Traffic Studies","volume":"245 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114191927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
