A heterogeneous latent class model of activity rescheduling, route choice and information acquisition decisions under multiple uncertain events - Sun Z, Arentze T, Timmermans H.
Travel information plays a central role in reducing uncertainty and persuading travelers to act in particular ways. It may result in activity-travel rescheduling decisions. The modeling of such behavior is relatively complex as it goes beyond simple route/...
All-terrain vehicles (ATVs) on the road: a serious traffic safety and public health concern - Denning G, Jennissen C, Harland K, Ellis D, Buresh C.
Objectives: On-road all-terrain vehicle (ATV) crashes are frequent occurrences that disproportionately impact rural communities. These crashes occur despite most states having laws restricting on-road ATV use. A number of overall risk factors for ATV-relat...
Analysis of the frequency and severity of rear-end crashes in work zones - Qi Y, Srinivasan R, Teng H, Baker R.
Objective: The objective of this study was to identify the factors that influence the frequency and severity of rear-end crashes in work zones because rear-end crashes represent a significant proportion of crashes that occur in work zones. Methods: Truncat...
Bicyclist-bicyclist crashes-a medical and technical crash analysis - Brand S, Otte D, Petri M, Müller C, Stübig T, Krettek C, Haasper C.
Background: The purpose of this study was to analyze the actual injury situation of bicyclists focusing on accidents involving more than one bicyclist. A medical and technical analysis was performed as a basis for preventive measures. Methods: Technical an...
Caffeine counteracts impairments in task-oriented psychomotor performance induced by chlorpheniramine: a double-blind placebo-controlled crossover study - Kim SW, Bae KY, Shin HY, Kim JM, Shin IS, Kim JK, Kang G, Yoon JS.
This study aimed to evaluate the effects of chlorpheniramine on psychomotor performance and the counteracting effects of caffeine on those sedative antihistamine actions. Sixteen healthy young men participated in this study. Using a double-blind placebo-co...
Calibration and validation of Highway Capacity Manual 2010 capacity model for single-lane roundabouts - Wei T, Grenard JL.
The 2010 edition of the Highway Capacity Manual (HCM 2010) provides new capacity models for single-lane and multilane roundabouts, which generally predict lower capacity than other popular models previously used in the United States. Acknowledging that bot...
Can patients receiving opioid maintenance therapy safely drive? A systematic review of epidemiological and experimental studies on driving ability with a focus on concomitant methadone or buprenorphine administration - Strand MC, Fjeld B, Arnestad M, Mørl
Objective: To perform a systematic review of the present scientific literature on the treatment with methadone or buprenorphine related to (1) traffic accident risk in epidemiological studies and (2) their effects on cognitive and psychomotor functions of ...
Characteristics of DUI offenders with a high versus low perceived risk of arrest - Beck KH, Ahmed AU, Farkas ZA.
Objective: To compare offenders with high versus low perceptions of risk for being stopped by police for drinking and driving using measures of beliefs, behaviors, social context of drinking, and perceived influence from a significant other in their social...
Commuter rail: balancing freight clearance with level boarding and Americans With Disabilities Act accessibility requirements - Nelson DO, Martinez E, Bonina S.
Federal regulators and passenger railways are both concerned about passengers with mobility impairments that limit their ability to use stairways. Federal policy and railway practice strongly encourage development of services that allow for level boarding ...
Concentrations of alprazolam in blood from impaired drivers and forensic autopsies were not much different but showed a high prevalence of co-ingested illicit drugs - Jones AW, Holmgren A.
Alprazolam is a benzodiazepine anxiolytic widely prescribed for treatment of panic-disorder and social phobias, although this medication is also subject to abuse. In this paper, the concentrations of alprazolam in venous blood samples from impaired drivers...
Consideration of sight distance in placement of concrete barriers on horizontal curves of roads - Sarhan M, Hassan Y.
Sight distance is an important criterion in highway geometric design. Many design elements, such as horizontal and vertical curvatures and offsets to lateral obstructions, must be checked so that drivers have sufficient sight distance to operate safely. On...
Crash modification factors for changes to left-turn phasing - inivasan R, Lyon C, Persaud B, Baek J, Gross F, Smith S, Sundstrom C.
This study estimated crash modification factors (CMFs) from before-after evaluations of two treatments targeted at reducing left-turn crashes at signalized intersections: (a) changes from permissive to protected-permissive phasing and (b) the implementatio...
Crash modification factors: Foundational issues - Hauer E, Bonneson JA, Council F, inivasan R, Zegeer C.
Crash modification factors (CMFs) are listed in the "Highway Safety Manual" and other authoritative publications. This information does not allow the reader to distinguish between the predictions of safety effect that can be made confidently and are likely...
Describing non-lane-based motorcycle movements in motorcycle-only traffic flow - Nguyen LX, Hanaoka S, Kawasaki T.
The motorcycle is the main transport mode for commuters in Vietnam because it costs less than a car and has greater mobility on congested city roads. A better understanding of the characteristics of motorcycle traffic flow can be helpful in formulating pro...
Development and assessment of taxonomy for performance-shaping factors for railway operations - Kyriakidis M, Majumdar A, Grote G, Ochieng WY.
Human performance is a significant contributor to railway incidents and accidents. The literature shows that train drivers, signalers, and controllers most affect network safety. Several studies have been conducted in the field of human factors and human p...
Development of left-turn lane warrants for unsignalized intersections - Fitzpatrick K, Brewer MA, Eisele WL, Zhang Y, Gluck JS, Levinson HS, Iragavarapu V.
Left-turn movements at intersections, including driveways--especially movements that are made from lanes that are shared with through traffic--cause delays and adversely affect safety. Although some left-turn warrants have been updated, many agencies still...
Development of the next generation of intercity corridor bi-level equipment with crash energy management - Martinez E, Nelson F, Prabhakaran A, Jones A.
An innovative rail car procurement specification was developed for bi-level equipment. This specification was developed to fulfill the Passenger Rail Investment and Improvement Act of 2008 (PRIIA). PRIIA is a congressional mandate to the National Railroad ...
Development of visual model for exploring relationship between nighttime driving behavior and roadway visibility features - Gibbons RB, Edwards CJ, Bhagavathula R, Carlson P, Owens DA.
Driving is often considered a visually oriented task. This visual task is constrained when drivers drive at night. Visibility is reduced because visual cues available during the day are not present at night. This study attempted to develop a link between d...
Does a medicinal dose of kava impair driving? A randomized, placebo-controlled, double-blind study - Sarris J, Laporte E, Scholey A, King R, Pipingas A, Schweitzer I, Stough C.
Overview: Increasing concerns over the potentially impairing effects of prescriptive sedative drugs such as benzodiazepines on driving have been raised. However, other alternatives such as natural medicines may also carry similar risks with respect to driv...
Drinking drivers and drug use on weekend nights in the United States - Voas RB, Lacey JH, Jones K, Scherer M, Compton R.
BACKGROUND: Studies of drinking drivers in alcohol-related crashes have shown that high breath-alcohol concentrations (BrACs) are associated with illegal drug use. Until the 2007 National Roadside Survey (NRS), the prevalence of drugs among drinking driver...
