Taiwan is no exception to this problem, because drunk driving is one of the primary causes of severe traffic crashes nationwide. To prevent DUI, the authorities have revised laws many times to increase the penalties for drunk driving, including revocation or suspension of license, greater fines, detaining vehicles, and lengthening incarceration times. However, under the current system, suspected drivers are only subject to an administrative punishment if they refuse the request of a sobriety test. By doing so, heavy drinkers could avoid a possible criminal accusation of drunk driving, a potential incarceration penalty, and a lifetime criminal record. This research investigates the opportunistic behavior of drunk drivers against DUI policies in Taiwan. First, we find that drivers with a previous DUI experience are more likely to refuse a breath test when caught. Second, the degree of probability to refuse a breath test increases as the punishment to drivers failing a breath test rises, while it drops as the punishment to refusers increases. Third, breath test refusers have a greater likelihood to be caught again for DUI violations in one year than heavy drinking drivers with a BrAC (breath alcohol concentration) level of 0.55 mg/L. Fourth, breath test refusers are somewhat more likely to cause a DUI incident in two years than drunk drivers who comply with the request to carry out a breath test. These findings suggest that the allowance of breath test refusal with a mild administrative punishment may be a loophole that limits the deterrent effect and consequently leads to more drunk driving cases and incidents among refusers.</div></div>","PeriodicalId":48355,"journal":{"name":"Transportation Research Part F-Traffic Psychology and Behaviour","volume":"107 ","pages":"Pages 848-860"},"PeriodicalIF":3.5,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142526272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To do so, we used time flexibility, defined as the tolerance for increased commute time (which can happen because of re-routing and picking up others when carpooling), as a proxy to willingness to carpool. Using structural equation modeling and survey responses from about 1000 workers and college students living in a rural county in Central Pennsylvania, we analyzed the sociodemographic, attitudinal, and situational factors that can lead to higher time flexibility when carpooling. We also investigated whether people’s time flexibility changes when they are offered monetary incentives (in terms of travel costs reimbursement). The results indicated that being a driving fan and seeking privacy when traveling reduces time flexibility, while being conscientious about environment and health leads to higher time flexibility. Moreover, females, people who had inconvenient past carpool experiences, and those living closer (within 20 min of driving) to their workplace/college showed lower time flexibility. On the other hand, people with lower income and higher driving costs were willing to tolerate longer commute times if reimbursed for a portion of their travel costs. We also found that if there is no initial level of willingness to carpool, reimbursement offers cannot do much to sway people’s decisions.</div></div>","PeriodicalId":48355,"journal":{"name":"Transportation Research Part F-Traffic Psychology and Behaviour","volume":"107 ","pages":"Pages 803-819"},"PeriodicalIF":3.5,"publicationDate":"2024-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142526269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this research, an augmented reality situation-adaptive human–machine interface (HMI) was simulated in a virtual environment. The HMI aimed to improve the quality of takeovers by boosting the reconstruction of situation awareness in distracted drivers following a takeover request in a Level 3 automated driving situation. To this end, the HMI displayed salient visual cues (bottom-up process) for important elements that drivers should pay attention to. Instructions from a user manual were also provided, detailing how to regain situation awareness by presenting the ideal takeover sequence (top-down process), which was necessary for the use of the HMI. For this purpose, an experiment was conducted using a medium-fidelity static driving simulator with a sample of 35 participants distributed according to three between-subjects conditions: “control – basic user manual without HMI,” “ideal takeover sequence focused user manual without HMI,” and “ideal takeover sequence focused user manual with HMI.” According to the results, the augmented reality HMI improved safety in takeovers involving lane changes in heavy traffic and emergency braking, with better traffic insertion and higher time to collision. Participants who only received the user manual dedicated to the ideal takeover sequence (top-down process) exhibited less visual exploration of the driving environment in the takeover situations, which could lead to safety issues. These results are discussed regarding existing literature and possible implementations of such an HMI in a simpler device, such as a head-up display, for provide wider application.</div></div>","PeriodicalId":48355,"journal":{"name":"Transportation Research Part F-Traffic Psychology and Behaviour","volume":"107 ","pages":"Pages 820-833"},"PeriodicalIF":3.5,"publicationDate":"2024-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142526270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to shed light on whether dotted extensions should be recommended in a transition area and research the impacts of dotted extensions on guiding drivers from their perspectives. Scenarios with and without dotted extensions were created for a video-viewing experiment. Driver eye movement behavior and cognitive load rating served as evaluation indicators in each target scenario. Thirty participants were recruited and randomly assigned to with and without dotted extension groups. Results show that: (1) With the dotted extension, participants could focus on fewer objects and, therefore, would not need to divert their visual attention toward the surrounding vehicles. (2) The dotted extension assists through-traffic drivers in maintaining more focused attention on information critical to their driving task. (3) Dotted extensions help drivers reduce stress, mainly because of clearer indications of lane configuration.
