The availability of advisory warnings via Vehicle-to-Vehicle and Vehicle-to-Infrastructure communication in the connected environments is expected to gradually increase over the next few years. Much of the research on advisory warning systems have examined driving behaviour in response to unexpected driving hazards; however, very little research has been conducted on common driving interactions such as interacting with pedestrians at pedestrian crossings. Therefore, the aim of this study is to investigate the effects of the connected environment on driving behaviour at pedestrian crossings. The connected environment was designed within the CARRS-Q advanced driving simulator. A combination of auditory (beep sound) and imagery message was simultaneously displayed on the windscreen to advise the driver on the presence of a pedestrian entering from a sidewalk. Seventy-eight licensed drivers drove the simulator in two driving conditions, namely, baseline and connected environment. The participants were 18–65 years old, and a third of them were females. Drivers' response to the driving aids and the braking behaviour were analysed in the latent response phase and the observable response phase, and the corresponding response times were modelled using the hazard-based duration modelling approach. In particular, this study applied the Weibull accelerated failure time model with shared frailty accounting for multiple observations from the same driver. Results showed that the time taken to respond to the pedestrian in the latent response phase was longer when the advisory warning was provided to the drivers, but the corresponding time in the observable response phase was shorter, indicating that drivers take an informed decision in the connected environment. Moreover, the safety margin—measured in terms of time-to-collision—was higher in the connected environment than the traditional driving environment, indicating a safer behavioural adaptation towards the connected environment.

在互联环境中，通过车对车和车对基础设施通信的咨询警告的可用性预计将在未来几年逐渐增加。许多关于咨询警告系统的研究都研究了应对意外驾驶危险的驾驶行为；然而，对于常见的驾驶交互（例如在人行横道处与行人的交互）进行的研究很少。因此，本研究的目的是研究连接环境对行人过路处驾驶行为的影响。互联环境是在 CARRS-Q 高级驾驶模拟器中设计的。挡风玻璃上同时显示听觉（哔声）和图像消息的组合，以告知驾驶员是否有从人行道进入的行人。七十八名有执照的司机在两种驾驶条件下驾驶模拟器，即基线和连接环境。参与者年龄在 18-65 岁之间，其中三分之一是女性。在潜在响应阶段和可观察响应阶段分析驾驶员对驾驶辅助设备的响应和制动行为，并使用基于危险的持续时间建模方法对相应的响应时间进行建模。特别是，本研究应用了 Weibull 加速故障时间模型，其中包含来自同一驱动程序的多个观察的共享弱点。结果表明，当向驾驶员提供咨询警告时，潜在响应阶段对行人的响应时间更长，但可观察响应阶段的相应时间更短，表明驾驶员在连接时做出了明智的决定。环境。此外，以碰撞时间衡量的安全裕度在联网环境中高于传统驾驶环境，表明对联网环境的行为适应更安全。
