Private vehicles have been greatly recognized as major contributor to denigrate the efficiency of urban networks and also major source of air pollutants. In general, various schemes have been employed to lessen the negative impacts that generated by private vehicles. In this respect, carsharing schemes have shown great potential to mitigate the adverse impacts of private cars. Carsharing has now become relatively broad concept and have been implemented in various forms such as rental agencies or carpooling, and likewise numerous studies have explored different aspects of carsharing. Different condition of vehicle ownership and examining captive rider responses are two distinct peculiarities distinguish this research from the other similar carsharing studies. Unlike the previous schemes in which cars had been provided by an organization, in this paper author plans to investigate the potential of ridesharing and the extent to which riders are willing to share their trips with the other people who have same route and destination.
Low level of the quality of public transport in terms of frequencies, asset quality and imperfect coverage has shifted trip-makers to merely using private cars in Tehran capital of Iran which then ultimately has been led to an over congested network. On the other side, the concept of carsharing is fairly new in Iran and perhaps due to uncertainties associated with the financial success of the scheme no action has been taken in this regard so far. As long as a new mode of transport is to be introduced, this study will employ Stated Preference Method and Discrete Choice Analysis creates the core of the analysis. Driving time and parking time are of the main attributes in this survey, as parking issues heavily affect on the individual’s mode choice. Accordingly various areas of the city have been chosen showing different levels of parking limitations. Accessibility to the private cars and public transport has been considered among all respondents. In parallel to discrete choice analysis, demographic features, educational levels of the individuals and respondents attitudes have been sought to be scrutinized in order to provide much more rational analysis. This paper depicts the results showing how different attitudes such as parking limitations affect respondents to choose an alternative, and how policy interventions could possibly enhance the outputs of the scheme.
