CHARACTERIZATION OF CRUSHED PORTLAND CEMENT CONCRETE RUBBLE AGGREGATE FOR URBAN ROADS
… for maintaining approximately 1,100 km of roads including locals, collectors, arterials, and freeways. With the aged state of the road infrastructure, increasing budget constraints limit the City’s ability to maintain existing road infrastructure to an acceptable level of service and to …

Analysis of right-turn lane length in left-hand traffic countries at signalised intersections of urban roads
Analysis of the right turn lane length of urban roads in left-hand traffic countries, such as Australia, UK and India (left-turn lane length in right-hand traffic countries such as USA), at signalised intersections encounters two main geometric features namely, deceleration length and storage …

Incidentalità in ambito urbano: studio del comportamento di guida in relazione alle caratteristiche geometriche dell’infrastruttura stradale
… relation to the geometric characteristics of the urban road infrastructure. This study allows the identification of factors which influence driving speed. The purpose is realizing mathematical models which link the driving behavior with the geometric characteristics of the infrastructure. Up to …

An economic model of highway fatalities
… per capita alcohol consumption, percentage of urban population, and percentage of urban roads. The highway fatality equation was estimated via an iterative approach using ordinary least squares. The variables testing significant include: average speed, speed variance, drinking age for beer, …

A Real-Time Server Based Approach for Safe and Timely Intersection Crossings
… in the number of vehicles, especially in urban areas. This manuscript focuses on traffic control at intersections, since urban roads with closely spaced intersections are often prone to queue spillbacks, which disrupt traffic flows across the entire network and increase congestion. While …

Functional Safety Assessment in Autonomous Vehicles
… operational domains such as rain, snow, freeway, urban roads, etc., system safety is paramount. Management of the system's safety throughout its life-cycle, from the conceptualization stage to the end of the lifecycle, is of primary importance. We describe a revision of functional safety standard …

International Analysis on the Traffic Impact of the COVID-19 Pandemic
… on weekdays and largest decreases on weekends. Urban roads showed a more rapid response to directives than rural roads. At the study period end, only China and Florida returned to pre-pandemic traffic levels, only China reported zero COVID-19 cases. Sweden experienced a similar COVID-19 curve as …

Dynamic analysis of a modern urban bus for assessment of ride quality and dynamic wheel loads
Modern urban buses with low floor and considerable over hung design are known to cause poor ride quality and excessive pavement loads. Such performance is partly due to the present status of urban roads and their rapid deterioration. On the other hand, variations in the dynamic tire forces of such …

Mind wandering during everyday driving
… mind wandering driving their own car on familiar roads. The second study built on the finding that drivers are most likely to report mind wandering on a familiar trip in their own car through an on-road study of drivers’ thoughts. Eleven drivers traveling in their own cars between home and work …

A framework for smart traffic management using heterogeneous data sources
… for determining missing roundabouts and urban roads flow distribution using constrained optimisation. Existing imputation methodologies have been developed on straight section of highways and their applicability for more complex networks have not been validated. This task presented a …

Investigating pedestrian safety solutions on rural high-order roads. Case-study: R71 Polokwane
… results in pedestrian fatalities. The ratio on urban roads is 1 in 10. The sobering pedestrian safety statistics describing South Africa's rural roads have prompted the need to research functional and effective traffic engineering solutions that can improve pedestrian safety on rural high order …

Il recupero dei vuoti: creare nuovi scenari urbani
A detailed urban road study cannot prescind from the theme of recovery of its role as heart of urban life. This premise implies a sub version of the common trend to consider the road as a non- place designed for the mere car transit. This presumed car hegemony is the main cause of degradation in …
