Population growth increase of vehicle ownership, and development patterns have resulted in greater levels of congestion, pollution, and crash frequency. A proposed solution to lessen current transportation system demands is to increase the share of bicycle trips. Furthermore, as cycling is perceived by some as both a dangerous and stressful mode of transportation, understanding the factors that lead to less comfortable and stressful riding, can help drive bicycle infrastructure development. To establish a more robust understanding of the behaviors of bicyclists and how infrastructure design and operations influence them, a bicycle simulator was used to evaluate bicyclist performance measures of velocity, horizontal displacement, and physiological responses (i.e., galvanic skin response) while riding in varying roadway conditions. Results showed that bicyclists in the bike lane condition, had a GSR reading 1.77 peaks per min less than when cycling in the no bike lane condition. When bicyclists were in no bike lane condition, the GSR reading was not affected by vehicle speed but it was affected by the vehicular volume. Additionally, females felt less comfortable when riding in either bike condition, even though they reported that they were “Strong and Fearless” riders. The methodology used for this study sets forth the foundation for future research that could evaluate varying facility designs and a wider range of individuals.

骑自行车者对变化的道路条件和自行车基础设施的行为和生理反应

人口的增长增加了汽车拥有量,并且发展模式导致了更高水平的拥堵,污染和撞车频率。减少当前运输系统需求的建议解决方案是增加自行车出行的份额。此外,由于自行车被某些人视为危险和压力大的交通方式,因此了解导致骑行不舒适和压力大的因素,可以帮助推动自行车基础设施的发展。为了对骑自行车的人的行为以及基础设施的设计和运营如何产生影响有更全面的了解,自行车模拟器被用来评估骑自行车者在不断变化的骑行过程中对速度,水平位移和生理反应(即皮肤电反应)的性能指标。巷道条件。结果显示,在没有自行车道的情况下,骑自行车的人在GSR上每分钟的GSR读数要少1.77个峰值。当骑自行车的人没有自行车道时,GSR读数不受车速的影响,但受车辆体积的影响。此外,即使女性报告称自己是“坚强而无所畏惧”的骑手,在任何一种自行车条件下骑行时,女性都会感到不舒服。本研究使用的方法论为将来的研究奠定了基础,该研究可以评估各种设施设计和更多个人。GSR读数不受车速影响,但受车辆体积影响。此外,即使女性报告称自己是“坚强而无所畏惧”的骑手,在任何一种自行车条件下骑行时,女性都会感到不舒服。本研究使用的方法论为将来的研究奠定了基础,该研究可以评估各种设施设计和更多个人。GSR读数不受车速影响,但受车辆体积影响。此外,即使女性报告称自己是“坚强而无所畏惧”的骑手,在任何一种自行车条件下骑行时,女性都会感到不舒服。本研究使用的方法论为将来的研究奠定了基础,该研究可以评估各种设施设计和更多个人。
