The current paper presents an AHP based approach for evaluating sustainable transport solution measures like car-sharing, park and ride, access control zones etc. In the first stage, we identify the indicators (criteria) for evaluating the transportation solution measure. These indicators (criteria) can be divided into several sub-indicators (sub-criteria). In the second stage, we allot weights to the indicators and sub-indicators using AHP. The values for the sub-indicators are measured using multiple sources and multiplied with their weights in order to compute state change variable values that form part of the city state equation. The respective values of the state change variables in the city state equation are then used to evaluate the efficiency of the transportation solution measure. Finally, we illustrate our approach by giving an example of car-sharing and measuring its impact on city environmental conditions.
