Better Integrating Travel Choices into Future Urban Mobility Systems: The Day the Highways Stood Still
This exchange between a scientist and an alien in the 2008 remake of The Day the Earth Stood Still summarizes the dilemma that is facing urban transportation today and that will continue to be a major issue in determining our ability to create a sustainable future. Many engineers and technologists think that they have the answers, while the crux of the matter lies in another popular quote provided by Walt Kelly in his April 1970 Earth Day comic strip Pogo: “We have met the enemy and they is us.”
Service quality of transit and demand-supply forecasting for ride-hailing in the Jakarta Greater Area, Indonesia
The extensive use of smartphones by individuals has led innovators to develop application-based transportation services. Ride-hailing systems have been extensively operated in more than 600 cities worldwide. With the competition between taxis and ride-hailing, the number of fleets must be regulated. Identifying factors that influence the demand of taxi and ride-hailing and how the quality transit service is very important. The aims of this research are to identify the factors that influence demand for taxis and ride-hailing and the service quality of taxis and ride-hailing service. The study identified socio-demographic and trip characteristics from 949 respondents in the Jakarta Greater area, Indonesia. Respondents interviewed about the waiting time, travel time and travel costs for the origin-destination of trips that are most often done using taxi, ride-hailing, and bus. The service quality of ride-hailing and taxi was analyzed based on the respondent’s preferences from an important-performance analysis survey. The forecasting demand of taxi and ride-hailing in the Jakarta Greater area using demand-supply model is 71,660 vehicles. The research findings are that service quality of ride-hailing is better than conventional taxis based on waiting time, travel time and travel cost variable.
