“…On the other hand, major constraints in promoting the use of this service include personal constraints, privacy and freedom of travelers, and limitations of carpooling service such as timeconsumingness and unpunctuality. These findings are different from other studies [3,20,24] in terms of personal and freedom factors, as previous studies have mostly focused on the service and operational aspects of carpooling service in comparison with other modes. These findings imply that the people who have strong belief on such constraints in traveling would not prefer carpooling service to their private vehicles.…”

“…Other factors may include incentives on carpooling service such as safety, time and money saving, trip purpose, age, travel frequency, disincentives on use of private vehicle and travelers' attitudes [8,14,[21][22][23]. According to the study by Malodia and Singla [24] in Indian cities, extra travel time, walking time to reach the meeting point, waiting time and cost savings are the influencing exploratory variables related to proper utility of carpooling service. Results of the ordered probit model reveal that the distance from carpooling meeting point, parking cost, Web application, matching preference and flexibility of services have significant relationships with people's propensity for ridesharing or carpooling [25].…”

Travelers’ attitudes toward carpooling in Lahore: motives and constraints

Traffic congestion has become a critical issue in developing countries, as it tends to increase social costs in terms of travel cost and time, energy consumption and environmental degradation. With limited resources, reducing travel demand by influencing individuals' travel behavior can be a better long-term solution. To achieve this objective, alternate travel options need to be provided so that people can commute comfortably and economically. This study aims to identify key motives and constraints in the consideration of carpooling policy with the help of stated preference questionnaire survey that was conducted in Lahore City. The designed questionnaire includes respondents' socioeconomic demographics, and intentions and stated preferences on carpooling policy. Factor analysis was conducted on travelers' responses, and a structural model was developed for carpooling. Survey and modeling results reveal that social, environmental and economic benefits, disincentives on car use, preferential parking treatment for carpooling, and comfort and convenience attributes are significant determinants in promoting carpooling. However, people with strong belief in personal privacy, security, freedom in traveling and carpooling service constraints would have less potential to use the carpooling service. In addition, pro-auto and pro-carpooling attitudes, marital status, profession and travel purpose for carpooling are also underlying factors. The findings implicate that to promote carpooling policy it is required to consider appropriate incentives on this service and disincentives on use of private vehicle along with modification of people's attitudes and intentions.

“…Daily emissions savings of up to 431.58 tonnes of CO 2 , 0.95 tonnes of NO x , and 0.046 tonnes of PM 2.5 were similarly estimated, which could result in monetary savings of up to €5,705 from reductions in CO 2 , €5,558 from NO x , and €9,210 from PM 2.5 . These findings are in line with those produced by Malodia and Singla (2016) and Ahern and Tapley (2008) whom similarly determined that the provision of incentives that lead to cost and time savings for the commuter would result greater mode shifting behaviour than the benefits associated with any other policies tested. The results from a study conducted by Mackett (2001) showed that improvements made to the route patterns and frequency of bus services could shift 215 short car trips to the bus.…”

The research presented in this paper investigates the behavioural response and subsequent appraisal of a range of policy incentives devised to encourage greater use of sustainable travel options within the Greater Dublin Area (GDA). Interventions were assessed by employing four-stage modelling techniques, as a tool to identify signs of mode shifting behaviour from single occupancy vehicle (SOV) use to public transport modes. Extensive modelling work was conducted in collaboration with the National Transport Authority (NTA) of Ireland utilising the National Regional Modelling System (RMS) to represent the sustainable policy changes. Parameter modifications in the mode and destination choice and trip assignment stages were made to account for improvements made to frequency, time and cost attributes of public transport modes included in the model. Subsequent changes in vehicle kilometres travelled of various modes modelled were then utilised to estimate the potential emissions savings. In addition to this, the potential monetary savings generated from a reduction in emissions were calculated. The key results produced from this study found that an increase in the mode share of public transport of up to 2.87% could be achieved in the GDA. Up to 1.76% of which was estimated to come directly from private car trips, as a result of implementing the policy incentives tested. Furthermore, daily emissions savings of up to 431.58 tonnes of CO 2 , 0.95 tonnes of NO x , and 0.046 tonnes of PM 2.5 were also estimated.

“…The attribute fare revealed a strong impact on the respondents' choice. Apparently, travelers attach high importance to low fares, thus confirming findings in the field of ridesharing that show cost savings to be one of the most influential attributes for using ridesharing [45]. The results are further in line with the findings of König et al [13] that proved the high importance of price for urban residents' appraisal of ridepooling systems.…”

Background: Ridepooling services have been predicted a bright future since they promise a flexible and usercentered mobility service. However, there is a research gap in examining the travelers' perception of ridepooling service characteristics since findings concerning fixed-scheduled public transport are hardly transferable. Methods: In order to shed some light on the human factors of ridepooling services a Discrete Choice Experiment (N = 410) was performed to identify travelers' preferences concerning ridepooling's service features. The study thereby focusses on the effect of trip purpose on the appraisal of the service attributes. Based on a literature review and a focus group six attributes of the operational concept were determined: fare, walking distance to the pickup point, time of booking in advance, shift of departure time, travel time and information. Results: The results underline that all of the six attributes significantly affected choice behavior. The appraisal of the service characteristics differed depending on the presented trip purpose. The willingness to pay was calculated for each service characteristics. The results give guidance for the user-centered design and operation of ridepooling systems that meet the requirements of the prospective passengers and thus facilitate behavioral shifts towards more sustainable mobility systems.
