8 Main Survey Results Pre-test Focus Group Survey firms Noise Maps Developing harmonised European approaches for transport costing and project assessment (HEATCO) Survey Results from Spain In general, participants found it very difficult to isolate valuations invoked by car traffic from the overall street noise. Actually, most of them failed to focus on the valuation scenario since the rest of the noise sources remained affecting them, and nothing was said about it.In general, participants found it very difficult to isolate valuations invoked by car traffic from the overall street noise. Actually, most of them failed to focus on the valuation scenario since the rest of the noise sources remained affecting them, and nothing was said about it. Another potential protest argument was the perception that the main source of car traffic noise is not heavy traffic but an extended non-civic behaviour in the population.Another potential protest argument was the perception that the main source of car traffic noise is not heavy traffic but an extended non-civic behaviour in the population. They suggested that the policy to counteract noise may contain other aspects such as an increase in the number of policemen in the streets to enforce civic behaviour (illegal parking, …)They suggested that the policy to counteract noise may contain other aspects such as an increase in the number of policemen in the streets to enforce civic behaviour (illegal parking, …) It was noted a potentially high correlation between the time the subject has been previously exposed to the noise and her preferences for silence.It was noted a potentially high correlation between the time the subject has been previously exposed to the noise and her preferences for silence.

9 Main Survey Results Pre-test Focus Group Survey firms Noise Maps Developing harmonised European approaches for transport costing and project assessment (HEATCO) Survey Results from Spain It was noted that the quality, and not only the quantity, of the activities that subjects carry out at home, could make a difference in the valuation results. That is, people who study or work at home complaint far more than others.It was noted that the quality, and not only the quantity, of the activities that subjects carry out at home, could make a difference in the valuation results. That is, people who study or work at home complaint far more than others. Participants showed relevant doubts about the proposed policy in the current wording. It can be suggested two alternative and more reliable wordings:Participants showed relevant doubts about the proposed policy in the current wording. It can be suggested two alternative and more reliable wordings: In any case, it seemed they did not fully trust a 100% of noise reduction. It was found more adequate to propose different levels of noise reduction and to elicit a full risk reduction valuation functionIn any case, it seemed they did not fully trust a 100% of noise reduction. It was found more adequate to propose different levels of noise reduction and to elicit a full risk reduction valuation function 1.Say that the cover has been already used in Europe with a 100 % of success 2.Use a headphone and car noise before and after the policy to convince individuals about the different in traffic noise with the cover

Subjects did not find credible the motorbikes scenario, and did not think anyone might pay for it.Subjects did not find credible the motorbikes scenario, and did not think anyone might pay for it. Subjects did not accept an increase in the municipality fee to cover the policies because they did not believe in current management. An ad hoc Association that collects money and guarantees their use in reducing traffic noise was somewhat more credible to the participants.Subjects did not accept an increase in the municipality fee to cover the policies because they did not believe in current management.

To the open question (how much would you WTP?), almost 90% stated reasons associated with costs rather that values. Also 100 % of them considered others WTP as a relevant aspect to state their own value. The independence assumption seems not to hold here.To the open question (how much would you WTP?), almost 90% stated reasons associated with costs rather that values.

Interviewer bias. During the pre-test all the misunderstandings, doubts, and questions that were expressed by the respondents were collected. This helped us to define a list of responses common to all the interviewers. This was possible only for the road traffic noise sample.Interviewer bias.

Respondents did not fully understand the link between Noise and Time Saving questions in the same survey. Scenario credibility. Respondents found it difficult to understand how traffic congestion can be reduced by paying extra money. The scenario was perhaps not concrete enough. (How my money can reduce traffic density?, what exactly am I paying? to whom? Is it a toll fee?). Scenario credibility.

By implementing an open-ended question and a bid design technique based on Cooper (1993) we find that the European bid design might not be an optimal design for the Canary Islands sample.
