To compete or not compete: exploring the relationships between motorcycle-based ride-sourcing,motorcycle taxis,and public transport in the Jakarta metropolitan area

Transportation - In the last decade, the emergence of ride-sourcing services has transformed personal trip behavior. In the context of Indonesia, ride-sourcing services have evolved into two modes...     

Motorcycle-based adolescents’ travel behaviour during the school morning commute and the effect of intra-household interaction on departure time and mode choice

We hypothesise that intra-household interaction influences home departure time and mode choice for the morning commute. In Indonesia, over 71% of vehicles on the road are motorcycles. This fact increases the significance of household interaction in influencing transport mode choice since the simplicity of the motorcycle allows a great degree of versatility in regard to multiple family member transport. To emphasise this point, our study focuses on the unique travel behaviour of adolescents during the school morning commute which, due to the use of the motorcycle, is a combination of the travel behaviour of accompanied children and escorting adults. Our study discovers that adolescents are likely to shift their school arrival time very early or close to the designated starting time in relation to motorcycle-based parental escort to school. In regard to mode choice, adolescent students prefer to be escorted by motorcycle rather than take public transport.     

The travel behaviour of ride-sourcing users,and their perception of the usefulness of ride-sourcing based on the users' previous modes of transport: A case study in Bandung City,Indonesia

Research provides evidence that ride-sourcing has not only substituted for private transport but also public transport. For further investigation of this substitution effect, this paper explores the travel behaviour of ride-sourcing users and those users' socio-demographic characteristics as well as perception of the usefulness of ride-sourcing based on the users' previous modes of transport before ride-sourcing existed. For these purposes, the study collected data using a questionnaire survey in Bandung City in 2018. We found that substitution from public transport exists for younger travellers, while substitution from private transport is most likely associated with infrequent and higher-income travellers. We also found open spaces, a green environment and high interaction society in the residential environments that have more association with high-income travellers, thus associated with lower use of ride-sourcing for former private transport users. This study found that travellers who resided in areas with similar, high-income characteristics tend to have a positive appreciation of ride-sourcing. It appears that the increasing perceived usefulness does not straightforwardly increase the frequency of usage. Therefore, travellers who lived in a more high-end and active social environment might appreciate the role of ride-sourcing services in some of their trips that complement another daily trip.     

Behavioral factors of motorcyclists in right-turn movements at unsignalized intersections: An insight from Yogyakarta,Indonesia

Conflicting actions of motorcyclists making right-turn movements (RTM) pose a considerable risk of accidents, which is of great concern when attempting to augment the level of safety at unsignalized intersections. This study was conducted to identify the habits of motorcyclists in RTMs, including normal RTM, weaving/merging RTM, and opposite indirect RTM when crossing unsignalized intersections. The behavioral factors were affected by gender, passenger status, motorcycle type, STOP factor, speed, travel time, and lane width of major and minor roads, which were tested using multinomial and nested logit models on 2358 motorcyclists. The results indicated that all of the observed variables significantly influenced motorcyclists' behaviors at unsignalized intersections, excepting the variable of travel time. The factors of speed and lane width on minor roads significantly correlated to motorcyclist behaviors during weaving and merging RTM only. The logit model reveals that female motorcyclists tend to make normal RTMs. The study also proposes ideal and practical recommendations, such as stop and speed regulations, channelization, number of lanes and lane widths, and maneuver markers, in order to address dangerous behaviors, in particular weaving and merging and opposite indirect-type RTMs.
