This thesis explores the acceptance and benefits of reducing the speed limit on Greek highways. Using a stated preference questionnaire, participants evaluated choices based on travel time, fuel consumption, and accident risk. Three scenarios were analyzed: (I) reducing the speed limit from 130 to 120 km/h, (II) reducing it to 110 km/h, and (III) no change, using binary and multinomial logistic regression models.
To assess economic viability, a Cost-Benefit Analysis (CBA) was conducted for the period 2023-2033, considering four factors: (a) road safety, (b) emissions reduction, (c) fuel consumption reduction, and (d) increased travel time. The reduction to 110 km/h was found to be viable, with a positive Economic Net Present Value (ENPV = €10,94 million) and a high Economic Internal Rate of Return (ERR = 55,8%).
This study provides valuable insights for policymakers and stakeholders, offering an in-depth understanding of public perception and acceptance of lower speed limits, which is crucial for developing effective and widely accepted road safety interventions in Greece.
