To relieve road congestion, a variety of transport demand management measures (TDM) have been implemented all over the world. The success of these measures has been found to depend at least partially on users’ perception about them. Several articles have jointly addressed the acceptability of public transport improvement (carrot policies) and road pricing (stick policies). However, these research works have not considered discounts on existing toll roads to relieve congestion on free alternative expressways. The objective of this paper is to study the combined acceptance of different congestion-calming policies at the suburban level, including the promotion of toll roads and measures to foster the use of transit. To that end, a survey was conducted among travelers on a commuting transport corridor in the region of Madrid aimed at exploring their perceptions towards four TDM measures, and a choice modeling framework was conducted. The scenarios considered are “carrot” policies, and the results of the analysis indicate that enhancing public transportation enjoys more support among respondents than toll promotions. Motorists using the free highway are more willing to use transit improvements than to opt for a toll road as an alternative regardless of the proposed toll discounts. Among the TDM measures explored, the least supported is the promotion of toll discounts associated with non-household carpooling. Furthermore, according to the results, the adoption of these TDM measures is more influenced by trip-related factors, in particular, the trip frequency and the mode of transport, than by socio-economic characteristics of the traveler. Finally, some geodemographic attributes of the residential location are also found to be statistically significant.

为了缓解道路拥堵，全世界已实施了各种运输需求管理措施（TDM）。已经发现这些措施的成功至少部分取决于用户对其的看法。几篇文章共同探讨了公共交通改善（胡萝卜政策）和道路价格（交通政策）的可接受性。但是，这些研究工作并未考虑在现有收费公路上打折，以缓解免费替代高速公路上的拥堵。本文的目的是研究郊区不同拥堵缓解政策的综合接受程度，包括促进收费公路和促进公交使用的措施。为此，在马德里地区通勤的交通走廊上对旅行者进行了一项调查，旨在探索他们对四种TDM措施的看法，并进行了选择建模框架。所考虑的场景是“胡萝卜”政策，分析结果表明，与收费促销相比，增强公共交通在受访者中得到了更多的支持。无论拟议的通行费折扣如何，使用免费高速公路的驾驶者都更愿意使用交通改善，而不是选择收费公路作为替代。在探索的TDM措施中，最不支持的是促进与非家庭拼车相关的通行费折扣。此外，根据结果，这些TDM措施的采用受旅行相关因素的影响更大，特别是，出行频率和运输方式，而不是旅行者的社会经济特征。最后，还发现了居民区的某些地理人口统计属性具有统计学意义。
