Thus, establishing speed limits and enforcing them are fundamental measures for promoting safe traffic. It is known that automatic speed enforcement, in particular, the average speed enforcement, effectively counters excessive speeds. In Brazil, only on site inspection of speed is regulated. Thus, testing the effectiveness of other countermeasures in reducing the average vehicle speed is indispensable. This study aimed to analyze the effects of a traffic education campaign (exposure of drivers to damaged vehicles on public roads) on the average speed behavior of drivers on urban roads who usually travel above the allowed speed. The average speeds of the (paired) vehicles before and after the introduction of the educational campaign in three segments were compared. The obatined results showed that the traffic campaign was effective in reducing the average vehicle speed by drivers who usually traveled above the allowed speed in the analyzed segments. The magnitude of the campaign effect (average speed reduction) was observed to be greater during its execution and lost strength when interrupted, especially on the sixth and seventh days after completion, corroborating that the traffic campaign measures (although low cost and easy to execute) had limited effects on the time and place of their realization. The results of this study can be used in the future as an indicator that people actually do worry about the consequences of speeding, as is the case with the vision of damaged cars.</div></div>","PeriodicalId":51534,"journal":{"name":"Travel Behaviour and Society","volume":"39 ","pages":"Article 100976"},"PeriodicalIF":5.1,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142816559","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}

We analyze the travel and activity behaviors of older adults living in areas with completely different urban and transportation paradigms, the United States and Tokyo, Japan, based on the 2017 National Household Travel Survey and the 2018 Tokyo Person Trip Survey. After we account for the potential residential selection bias, we find that older people living in denser and more accessible environments in transit societies in Tokyo, Japan tended to conduct more active and transit tours but fewer automobile tours and shorter travel. Moreover, these older adults were more likely to be engaged in social, shopping, and recreational activities. For their counterparts in the U.S., built environments were found to have moderate impacts, but the possession of driver license and household vehicles showed greater explanatory power, which could be related to the country’s automobile-oriented culture.

These three components of the system are interconnected. Both networks share common transfer stops in the main corridors of the central city while park-and-rides are the access points to the interurban network in the periphery. Consequently, the model introduces the concept of coupled networks to define the interrelations between two transit services and the park-and-ride facilities.

This paper aims to address this by investigating how the development of car- and bike-sharing services is affected by Flexible Parking Requirements. We study four cases based on mobility service providers and specific properties in Sweden through the lens of business model literature and actor-network theory.

Bike-sharing services were characterized by diverse weaknesses and threats that must be addressed for functioning services. The results indicate Flexible Parking Requirements being an important actant of change in defining the services offerings and shaping assemblages. A plethora of actants is identified in the assemblage around car- and bike-sharing services.

Data for this analysis was sourced from a mobile navigation application, covering 34 cities within China, thereby enabling the analysis of individuals within each latent class to reveal their diverse preferences for using public transit within different cities. Our findings indicate significant individual differences in response to incentives, categorized into three main latent classes: Class 1 individuals exhibit minimal influence from incentives; those in Class 2 demonstrate moderate responsiveness, especially to food and shopping coupons; and Class 3 individuals, whose decision-making is significantly affected by education level, gender, and travel mode preference, show a high degree of responsiveness to incentives.
