Equity & LiveabilityAfter Ecopass implementation the traffic congestion within the charged area during peak hours has decreased. By considering the ratio between flow and capacity of roads1] an average decrease of 4.7% has been calculated during the period between January and December 2008. Moreover it has been noticed a decrease of 25.1% of km of congested roads.
As a consequence the average vehicle speed has increased by 4% during morning peak hours, while the total time saved expressed as hours/day of trips by private vehicle has been equal to 750 hours within Ecopass area and 2,550 hours outside the area. By taking into account an economic value of time saved equal to 8 €/hour for private vehicles and 42 €/hour for commercial vehicles, the economic value of time saved is of 9.2 M€/year.
Road SafetyFrom data analysis of the first year of Ecopass it has been noticed a decrease in accidents within Ecopass area with a total accidents decrease of 14.4% (- 4.6% outside the areas) and of 14.2% (- 6.7% outside area) of accidents with injured people both in respect of year 2007.
1] The flow/capacity ratio indicates the usage extent of the capacity offered by the road network in respect of the total of vehicles circulating on these roads. It has estimated as the ratio between the sum of km travelled and the sum of roads capacity multiplied by the length of each road. The length of congested network is given by the sum of roads where the traffic volume exceeds the 90% of road capacity.
