Value of travel time, or interchangeably, value of time (VOT) has been a crucial instrument for travel demand modeling, travel behavior analytics, transport policy, and investment evaluation. With the introduction of autonomous modes, such as autonomous vehicles (AVs), but also autonomous Urban Air Mobility (UAM), the perception of VOT is fundamentally changed as AVs enable individuals the capability of performing multiple tasks while traveling. VOTAVI aims at defining a novel methodological framework for the estimation of VOT in the era of AVs, utilizing innovative data collection methods that would allow to explore more thoroughly the impact of latent personal characteristics on their choices. VOTAVI will systematically examine, based on a critical assessment of the current state of the art of value of timing research and offer innovative improvements that reflect emerging lifestyles, technological breakthroughs, and new mobility concepts in different activity contexts. The potential of receding from the travel time minimization paradigm in the era of autonomous vehicles requires the identification of the factors that influence perceptions on travel (including new sets of lifestyles, preferences, and behaviors). VOTAVI goal is twofold: a) provide an exploration of these factors by the creation of a series of surveys that would investigate the value of travel time in a novel use of both revealed preference (RP) and stated preference (SP); and b) explore the potential of novel data collection techniques to provide a more thorough investigation for the exploration of VOT changes. This investigation will be implemented through the development of both a web-based stated preference survey and a smartphone app. The developed instruments will allow assessing the potential impact of AVs on VOT perception by considering in-vehicle activity participation, individual personality traits, attitudinal towards AVs, and other conventional factors like transport mode, trip purpose, distance traveled and reliability. Based on the collected empirical data, the project will develop new methodologies using discrete choice models to investigate VOT under different scenarios of AVs. The project is organized into four work packages. WP1 is devoted to web-based SP experiments design and implementation for VOT estimation. WP2 contributes to smartphone application prototype development. WP3 is dedicated to RP/SP experiments using the smartphone-based app for both pilot studies and its wide deployment. WP4 is devoted to data analysis and model development for VOT estimation. We adopt flexible project management with overlaps between the WPs.

旅行时间价值（或可互换的时间价值（VOT））已成为出行需求建模，出行行为分析，交通政策和投资评估的重要工具。随着自主模式的引入，例如自主车辆（AV）以及自主城市空中交通（UAM），人们对VOT的看法发生了根本性的变化，因为AV使个人能够在旅行时执行多项任务。VOTAVI旨在定义一个新的方法框架，用于在AV时代估计VOT，利用创新的数据收集方法，可以更彻底地探索潜在的个人特征对他们选择的影响。VOTAVI将系统地研究，根据对计时研究价值的当前艺术状态的批判性评估，并提供创新的改进，反映新兴的生活方式，技术突破和不同活动环境中的新移动概念。在自动驾驶汽车时代，从旅行时间最小化范式中退出的潜力需要识别影响旅行感知的因素（包括新的生活方式，偏好和行为）。VOTAVI的目标是双重的：a）通过创建一系列调查来探索这些因素，这些调查将调查在显示偏好（RP）和陈述偏好（SP）的新用途中的旅行时间的价值;以及B）探索新数据收集技术的潜力，以提供对VOT变化的探索的更彻底的调查。这项调查将通过开发基于网络的陈述偏好调查和智能手机应用程序来实现。开发的工具将允许通过考虑车内活动参与，个人个性特征，对自动驾驶汽车的态度以及其他传统因素（如交通方式，出行目的，行驶距离和可靠性）来评估自动驾驶汽车对VOT感知的潜在影响。根据收集的经验数据，该项目将开发使用离散选择模型的新方法来研究不同AV场景下的VOT。该项目分为四个工作包。WP 1致力于基于Web的VOT估计SP实验的设计和实现。WP 2有助于智能手机应用程序原型开发。WP 3致力于使用基于智能手机的应用程序进行RP/SP实验，用于试点研究及其广泛部署。WP 4致力于VOT估算的数据分析和模型开发。我们采用灵活的项目管理，在工作计划之间有重叠。
