Drivers are estimated to contribute an overwhelming proportion to the burden of traffic crashes, as factors that increase crash risk are frequently due to unsafe driving behaviours. The relationship between risk perceptions and people’s risky driving behaviours is still not well understood. This paper aims to further analyse the potential effect of risky driving behaviours on drivers’ perceptions of crash risk and differences in perceptions among drivers. Crash risk perceptions in an inter-city, ...

The Algerian Government has recently promoted transportation projects such as the Algiers metro and tramway services that represent a key part of its political and financial effort to improve mobility in the country. However, public transport systems' profitability requires a thorough diagnosis of the services provided based on users' perceptions and expectations. That is, to invest money according to users' requirements. A methodological approach, which combines an Importance-Performance Analysis ...

Research on involvement of public transit customers, which can be defined as the level of interest or importance of public transit to a passenger, is scarce and no study has attempted to comprehensively analyze this concept in the public transit sector. Based on behavioral and marketing literature, this paper tests three possible roles of involvement in regards to passengers' perceptions of a Light-Rail Transit (LRT) service in Seville (Spain): the mediator, moderator and antecedent roles. The structural ...

Existing approaches dealing with customer perception data have two fundamental challenges: heterogeneity of customer perceptions and simultaneous interrelationships between attitudes that explain customer behaviour. This paper aims to provide practitioners with a methodology of service quality (SQ) evaluation based on public transit customers behavioural theory and advanced market segmentation that deals with these two fundamental challenges. The original contributions of this paper are: the definition ...

Rapid urban growth puts pressure on local governments to rethink how they manage street curb parking. Competition for space among road users and lack of adequate infrastructure force delivery drivers either to search for vacant spaces or to park in unsuitable areas, which negatively impacts road capacity and causes inconvenience to other users of the road. The purpose of this paper is to advance research by providing data-based insight into what is actually happening at the curb. To achieve this ...

Pickup and delivery operations are an essential part of urban goods movements. However, rapid urban growth, increasing demand, and higher customer expectations have amplified the challenges of urban freight movement. In recent years, the industry has emphasized improving last-mile operations with the intent of focusing on what has been described as the last leg of the supply chain. In this paper, it is suggested that solving urban freight challenges requires an even more granular scale than the ...

Increased use of ridesourcing leads to increased pick-up and drop-off activity. This may slow traffic or cause delays as vehicles increase curb use, conduct pick-up and drop-off activity directly in the travel lane, or slow to find and connect with passengers. How should cities respond to this change in an effort to keep travel lanes operating smoothly and efficiently? This research evaluates two strategies in Seattle, WA, in an area where large numbers of workers commute using ridesourcing services: ( ...

Abstract There is growing pressure in cities to unlock the potential of every public infrastructure element as density and demand for urban resources increase. Despite their historical role as providing access to land uses for freight and servicing, alleys have not been studied as a resource in modern freight access planning. The authors developed a replicable data collection method to build and maintain an alley inventory and operations study focused on commercial vehicles. A Seattle Case study ...

The present study was designated to evaluate the antileishmanial activity of acid and basic fractions that were obtained after acid-basic extraction, from ethanolic 70% crude extract and pure compounds from the stem bark of Aspidosperma ramiflorum. The basic alkaloidal fraction presented a good activity against the extracellular form (promastigotes) of Leishmania (L.) amazonensis (LD50 value<47 μg/ml). Based on these findings, the basic fraction was fractionated on silica gel column chromatography ...

A relevant aspect of traffic accident analysis is to identify the key factors affecting road users' driving behaviour and attitudes. Traditional considerations of traffic safety focus on physical environment, vehicle and road user. Among these, road users' driving behaviour plays an important role. The aim of our work is to investigate the relationship among road accident severity, users' driving behaviour and socio-economic characteristics, by comparing data from two urban areas having different ...

Because most traffic accidents are caused by the human factor, intervention programs should work to prevent and reduce these fatal incidents by focusing on drivers. The human factor relates to aspects of risk that are controlled by people, for example, whether or not people follow driving rules, their attitude and behavior while driving, and so on. Furthermore, road userś perception of risk influences their driving behavior. As a result, this study investigates the key factors that affect drivers' ...

Ecological processes are centered to water availability in drylands; however, less known nutrient stoichiometry can help explain much of their structure and ecological interactions. Here we look to the foliar stoichiometry of carbon (C), nitrogen (N), and phosphorus (P) of 38 dominant plant species from the Sonoran Desert, grouped in four different functional types to describe ecological characteristics and processes. We found that foliar N, C:N, C:P, and N:P stoichiometric ratios, but not P, were ...

The 80% of the world's cattle population (approximately 1281 million), 80% are at risk for ticks and tick-borne diseases. Over a decade ago, the estimated global costs of control measures and productivity losses amounted to $7.0 billion USD annually (7 USD/head/years). Tick control in livestock remains, to a large extent, based on chemical acaricides, but their use in combination with anti-tick vaccines and utilization of host resistance to ticks should reduce dependency on chemical tick control. Currently ...

The main drivers of diversification of freshwater fishes in Cuba are not yet well understood. For example, salt tolerance was thought as the main factor involved in the diversification of Gambusia punctata species group in this archipelago. However, evidence from a recent DNA barcoding survey suggested the presence of cryptic species and no correlation between species delimitation and level of salinity. In this study, we analyzed the cryptic diversification of G. punctata species group in Cuba, ...

In the research on mathematics education, numerous Likert-type instruments estimating attitudes toward mathematics are sometimes composed of factors with a high correlation, which can make it difficult to assign the statements from the scale to each estimated factor. Further, the measurement of attitudes is usually done by adding the scores but ignoring the existence of possible differences in the importance that each item can have in its factor estimation. A revision of the methodology for the ...
