Several past studies developed acceleration/deceleration rate models as a function of a single explanatory variable. Most of them were spot speed studies with speeds measured at specific locations on curves (usually midpoint ...
Speed prediction models are commonly developed using maximum and minimum operating speeds measured at or within specific locations on the tangents and horizontal curves, respectively. However, the actual distribution of ...
This study developed operating speed prediction models on tangents, curves, and tangent-to-curve transitions for heavy passenger vehicles (HPVs), using continuous speed profiles. Continuous speed profile data for HPVs were ...
The comfort threshold is one of the basic controls in designing horizontal alignment. Some studies have implied that the recommended comfort thresholds are conservative because they were determined using the traditional ...
Several past studies showed that Autonomous Vehicles (AVs) can reduce crash risk, stop-and-go traffic, and travel time. To analyze the safety benefits of AVs, most of the researchers proposed algorithms and simulation-based ...
Several studies have measured the minimum operating speed on horizontal curves to model the operating speed to assess the geometric design consistency. Most of these studies approximated equal lengths of deceleration and ...
A large number of reported road collisions are caused by driver inattention, and inappropriate driving behaviour. This study investigated the effectiveness and acceptance of Advanced Driving Assistance Systems (ADAS) for ...
In response to the rising trend in the promotion and adoption of cycling, ensuring cyclist safety is paramount. Understanding behavioural causes of crashes and identifying collision hotspots is important; however, the ...
This study assesses the predictive performance of three gradient-boosting Machine Learning (ML) models, Gradient Boosting Machine (GBM), eXtreme Gradient Boosting (XGBoost), and Light Gradient Boosting Machine (LightGBM), ...
Structural concrete of a designed strength can be produced for specific requirements by using the accepted methods of mix design but the present Indian standards on mix design does not takes into account the procedure for ...
This book explores recycling and reusing construction wastes as alternative coarse aggregates and presents this as a possible solution for the major challenge of making sustainable concrete. It explores the reduction of ...
In recent years, structural lightweight concrete has gained momentum in its use due to its superior properties in terms of dead load reduction, better thermal comfort, improved fire resistance, etc. The use of lightweight ...
The present study developed a relationship between the (a) compressive strength and static Modulus of Elasticity (MOE), (b) compressive strength and dynamic MOE, and (c) the static MOE and dynamic MOE for sintered fly ash ...
The infrastructure growth in the world is expected to result in huge requirement of 12.5 billion tonnes of coarse aggregates in 2050. The utilization of artificial aggregates can pave a feasible pathway for tackling the ...
In the previous chapter, we have discussed the pressing need for a durable and green concrete. Use of recycled concrete aggregates as coarse aggregate replacement and other SCMs as partial cement substitute can become ...
Concrete comprises of three different phases such as (1) aggregate, (2) hardened cement matrix and (3) interfacial transition zone (ITZ) between the aggregate and matrix. Heterogeneity in concrete at the microstructural ...
Sustainable concrete production demands satisfaction of the two most important criteria such as optimization of resources and minimization of end-of-life wastes. As discussed in the previous chapters, one of the important ...
Flat slab supported by an interior column is a complicated problem due to the most likely phenomenon of punching shear failure. This chapter discusses the punching shear behaviour of recycled aggregate concrete with coarse ...
Concrete constituted of coarse recycled concrete aggregate and supplementary cementitious materials must display technical properties similar to or within an acceptable range of deviation when compared to the existing ...
The use of concrete construction has never been so rampant before and the demand is continuously rising. As a result, the environment is overburdened with the increased CO2 emissions associated with cement and exploitation ...
