Abstract

Transportation is the foundation of daily life and is vital to a region's economic and social development. Transportation is a crucial aspect of human life, facilitating connections between locations. Mode choice is a critical consideration in transportation planning, influenced by cost, travel time, and comfort factors. This study aims to analyze the characteristics of travelers in Bitung City Regency and the factors influencing their choice of transportation modes in 2024. The research involved distributing an online questionnaire to 200 respondents and gathering data on various latent variables, including Travel Cost, Travel Time, Vehicle Condition, and Comfort Level. The analysis used Structural Equation Modeling (SEM) with SPSS and AMOS software. The study revealed a significant gender disparity among the respondents, with men dominating the demographics at 60%. Most respondents were from the 26–35-year age group (40%), had a private status (35%), and had completed high school or vocational school (35%). Motorbikes were the most common regarding vehicle ownership, with 60% of respondents owning one. The SEM analysis revealed significant factors influencing transportation mode choice. Travel Time (WT) had a negative effect on Comfort Level (TK) and Vehicle Condition (KK), with t-values of -0.684 and -0.895, respectively, indicating that longer travel times reduce comfort and vehicle satisfaction. Vehicle Condition (KK) significantly influenced the preference for Online Transport (TO) and Conventional Ojek (OK) with t-values of 0.597 and 0.278, respectively. Comfort Level (TK) significantly impacted the preference for Public Transport (TU), Conventional Ojek (OK), and Online Transport (TO) with t-values of 0.728, 0.530, and 0.301, respectively. The findings of this research have practical implications, suggesting that enhancing travel time efficiency, vehicle conditions, and overall comfort can significantly influence mode choice preferences. These insights can engage and interest transportation planners, policymakers, and researchers, guiding future transportation planning and policymaking in Bitung City Regency.

Abstract

Tomohon City is city in the province of North Sulawesi, Indonesia, which is enclave from Regency Minahasa with amount sufficient school? many . Some schools located on the edge road main , where vehicles passing by with speed very dangerous height for children the school that will cross way to go or when going home from school. Children are often careless and spontaneous, so they have the potential to become victims of traffic accidents. Evaluation of the implementation of the School Safe Zone (ZoSS) needs to be carried out, so that the behavior of pedestrians and drop-off behavior can be known, whether they have behaved safely or not. Then we can draw conclusions whether the School Safe Zone has been effective in its implementation or not. SD Negeri 2 Tomohon and SD Lentera Harapan Tomohon are located on the edge of the main road so they were chosen as research locations because in front of these two schools there is a School Safe Zone (ZoSS) that needs to be evaluated. These two School Safe Zones will be evaluated based on the Decree of the Director General of Land Transportation Number 3582 / AJ.403 / DRDJ / 20018. The research was conducted for 3 days at each location, and was carried out directly including data on the completeness of School Safe Zone (ZoSS) facilities, data on pedestrian behavior and data on drop-off behavior. Speed data and volume data were taken based on references to the 2023 Indonesian Road Capacity Guidelines (PKJI) which will then be processed to obtain the level of service of the road sections studied. From this study, the data on pedestrian and usher behavior in both research locations can be stated as “not yet safe” with Zcount > Ztable. Based on the results of the service level analysis for the Jl. Sam Ratulangi section (SD Negeri 2 Tomohon), the capacity was obtained 3376 smp/hour, the peak hour volume ranged from 374 smp/hour – 788 smp/hour with a service level of service level B during peak hours. While for the Jl. Makmur section (SD Lentera Harapan Tomohon), the capacity was obtained 3440 smp/hour, the peak hour volume ranged from 705 smp/hour – 985 smp/hour with a service level C during peak hours. Therefore, it is necessary for schools to pay attention to educate students about safety in crossing the road, and for the government, especially the Tomohon city transportation agency, to socialize the intent and purpose of implementing the School Safe Zone (ZoSS) for other road users in order to create comfort and safety for road users
