Bristol Airport is a regional airport based in the South West of England. It has plans to increase capacity from 10 to 12 million passengers per annum. The airport has planning obligations with North Somerset Council, which include obligations on air quality. One of the airport's challenges relates to surface access and reducing the use of single occupancy vehicles. This challenge is shared among most airports globally, many of whom have sought to pinpoint the factors influencing this usage. This research aimed to find the contributing factors affecting users at Bristol Airport with a particular focus on employees to make strategic recommendations. A mixed method approach, through the use of questionnaires and an employee specific focus group led to findings that indicated common factors among employees namely convenience and reliability as the main influences reducing the stress of travel. There were secondary factors such as cost, and family commitments, which was the main differentiator between employee and passenger choice factors as evidenced in the literature. The number of meaningful strategic interventions at Bristol was found to be limited. There is some evidence pointing to the potential popularity of airport employee incentive schemes such as the use of discounted hybrid cars. This would help reduce emissions but not single occupancy private vehicle usage. This research provides Bristol Airport with firm grounds to continue investigating the plethora of factors and possible sustainable strategies to meet their environment related planning obligations.

布里斯托尔机场是位于英格兰西南部的地区性机场。它计划将运力从每年 10 人增加到 1200 万人次。机场对北萨默塞特郡议会负有规划义务，其中包括空气质量义务。机场面临的挑战之一与地面通道和减少单人车辆的使用有关。全球大多数机场都面临这一挑战，其中许多机场都试图找出影响这种使用的因素。这项研究旨在找出影响布里斯托尔机场用户的因素，特别关注员工提出战略建议。混合方法的方法，通过使用问卷和员工特定的焦点小组得出的结果表明，员工之间的共同因素，即便利性和可靠性是减少旅行压力的主要影响因素。有诸如成本和家庭承诺等次要因素，这是文献中证明的员工和乘客选择因素之间的主要区别。发现在布里斯托尔进行有意义的战略干预的数量是有限的。有一些证据表明机场员工激励计划可能很受欢迎，例如使用打折的混合动力汽车。这将有助于减少排放，但不利于单人使用私家车。
