Are long-haul truck drivers unusually alert? A comparison with long-haul airline pilots.
2020
Abstract Background Recent studies suggest heavy vehicle drivers self-estimate their sleepiness unexpectedly low during night duties. The present study compared sleepiness ratings of long-haul truck drivers with those of long-haul airline pilots during night and non-night duties. In addition, the correspondence between self-rated manifest and predicted latent sleepiness was examined in the two groups. Methods Twenty-two drivers and 33 pilots participated. Their working hours, sleep, on-duty sleepiness, and use of sleepiness countermeasures were measured in naturalistic conditions. Predictions of latent sleepiness were based on the measurements of working hours and sleep using the Sleep/Wake…
Public acceptance of semi-automated truck platoon driving. A comparison between Germany and California
2020
Abstract Platooning technology aims at achieving fuel savings by reducing the distance between two or more electronically coupled vehicles. This technology has recently been tested on public highways with heavy trucks in Germany and California. The objective of this study is to assess the level of acceptance among other road users as well as influencing factors of acceptance. An online questionnaire was administered in Germany and California with a total of N = 536 participants. They received information about truck platoon driving (level-1 and level-2 automation) and answered questions about their attitudes towards the technology as well as their behavioral intention to cooperate with the …
The self-reported causes of sleepiness in shift-working tram and truck drivers
2021
Identifying the causes of sleepiness in various safety-critical work environments is neces-sary for implementing more efficient fatigue management strategies. In transportation, little is known about drivers' own perceptions of these causes. Therefore, we instructed shift-working tram (n = 23) and long-haul truck drivers (n = 52) to report at the end of their shifts what made them sleepy if they felt so. These self-reports, measured on-duty sleepiness, and sleep amounts were recorded on every shift over a period of 2-3 weeks per driver. The causes of sleepiness were queried with smartphone applications and sleep logs. Sleepiness was measured with the Karolinska Sleepiness Scale (KSS) and sl…
Ranking world tourist destinations with a composite indicator of competitiveness: To weigh or not to weigh?
2019
Abstract This paper contributes a weighted composite indicator of competitiveness for 136 world tourist destinations. To that end, Data Envelopment Analysis and Multi-Criteria-Decision-Making techniques are used with raw indicators from the 2017 edition of the Travel & Tourism Competitiveness Report of the World Economic Forum (WEF). An outstanding feature of our approach is that weights are endogenously generated. Furthermore, the role played by several variables in tourism competitiveness is assessed using truncated regression and bootstrapping. The ranking of world tourist destinations produced by our weighted composite indicator of competitiveness is, however, fairly similar to that der…
Passenger Car Equivalent for Heavy Vehicles Crossing Turbo-roundabouts
2016
Abstract Turbo-roundabouts represent an innovative scheme of modern roundabouts which provides a spiraling traffic flow and requires drivers to choose their direction before entering the intersection, since raised lane separators mark the lanes on the ring. The configuration of the turbo-roundabout makes that patterns of conflict at entries with one and two conflicting traffic streams can coexist. This paper presents research efforts aimed at measuring quantitatively the effect of heavy vehicles on operational conditions of a turbo-roundabout. The study starts from the initial belief that the greatest constraints to the vehicular trajectories imposed by the turbo-roundabout necessarily impl…
Airline Loyalty Determinants among Business Travelers: Empirical Evidence from Croatia
2017
AbstractAirline passenger loyalty has been the subject of several studies set within a general travel context. These studies have helped understanding the influence of variables like brand equity, airline service levels, customer commitment, but also price in tying a passenger to a particular airline. Despite the great economic importance of the business traveler market, no study has, however, so far, exclusively focused on this traveler segment and tried to investigate drivers of repurchase intentions and loyalty of this specific traveler type. This study aims to address this research gap. The findings reveal that business passenger loyalty is far stronger driven by emotional than rational…
The effect of cooperative infrastructure fees on high-speed rail and airline competition
2021
Abstract This paper explores the effects of cooperation between rail and air infrastructures in setting per-passenger fees prior to competition among airlines and high-speed rail (HSR) in a transport network. It is shown that, for a sufficiently low degree of substitution, cooperation results in lower fees and greater HSR traffic than under competition. Besides, it leads to more connecting passengers. An empirical application allows for a quantitative assessment of cooperation. Gains to passengers and operators are sizeable when cooperation either involves all infrastructure managers or the rail and the hub airport managers. Welfare gains are in the range of 10.4–11.1%. Our contribution off…
Increasing the attractiveness of a cruise port for cargo business: The contribution of stakeholders
2021
Abstract Cruise and cargo operations, though distinct seaport activities, have sufficiently similar functions that by accommodating cargo business in a largely cruise domain, a port may achieve increased attractiveness and better resource utilization. We sought to conceptualize a framework by which an existing cruise port can integrate divergent stakeholder interests to achieve port attractiveness under this duality. We adopted a qualitative approach involving in-depth interviews with experts representing the port authority and key stakeholders at Port Canaveral, the second busiest multi-day cruise embarkation port in the world. We identified a supply chain integration model as a pathway to…
The production of “rhythms of responsibility” for childcare in a post-socialist society
2021
Drawing on 32 face-to-face interviews with mothers and childcare providers in Latvia, this paper examines the mundane mobilities. We argue that attention to mundane mobilities reveals crucial arran...
A Gamified Mobility Experience
2020
We believe in the use of urban games to define new enjoyable experiences, change citizens’ unsustainable habits and educate them to new environment-and social-friendly ones. This paper presents MUV, an innovative action that has the power to engage citizens and foster sustainable mobility behaviors. MUV complements engaging HMIs with a participatory method within an iterative innovation process called the virtuous cycle (understand, involve, co-create, implement, experiment). The innovation process has led to a new game dynamic: Mobility as a Sport. It results in a rewarding personal mobility experience; the same rewarding sensations the athletes feel when they improve their results.
