Abstract

The solution to the transportation problem lies in assessing the performance of related road sections and intersections, and analyzing different traffic management schemes to optimize efficiency. This study aims to compare the performance of a road network simulation model for the Pahlawan road area. Data analysis includes examining origin-destination matrices, vehicle free speeds, vehicle behavior, and intersection control. The simulation model, calibrated and validated using Vissim, represents real-world conditions. Implementing SLFF (Single Lane Free Flow) and MLFF (Multi Lane Free Flow) systems at toll gates (scenarios 1 and 2) reduced queues, particularly at the Pancasila Monument Roundabout and Jalan Jati Raya. Adding a new toll gate via Jalan Kahuripan further improved traffic on Jalan Pahlawan compared to scenarios 1 and 2. However, converting the Gelora Delta roundabout into an underpass without additional measures worsened toll gate queues. Effective traffic performance can be achieved by combining the Gelora Delta roundabout underpass with either the SLFF toll payment system (scenario 5), MLFF (scenario 6), or the addition of a new toll gate (scenario 3).

Abstract

This study analyzes the construction requirements for rigid (concrete) and flexible (asphalt) pavements on the Temuireng-Jetis road section in Mojokerto District, focusing on the cost-effectiveness and efficiency of both options. The research compares pavement thickness design, cost, and implementation time using the 2017 Pavement Design Manual (MDPJ) and Pd T-14-2003 standards. Data was collected through field surveys and reports from the Mojokerto District Public Works Office. The findings indicate that rigid pavement, with a 25 cm thickness, offers greater long-term economic advantages compared to flexible pavement due to its superior durability, reduced maintenance needs, and better performance under heavy traffic. Although rigid pavement has higher initial construction costs, it proves more cost-effective over time. Flexible pavement, while cheaper initially, incurs higher maintenance costs and is more prone to damage in high-traffic areas. The study recommends using rigid pavement for roads expected to support heavy vehicles and require extended service life. In conclusion, this research provides valuable insights into selecting the appropriate pavement type based on cost, durability, and long-term benefits, offering practical guidance for policymakers and engineers in Mojokerto and other regions facing similar infrastructure challenges.

Abstract

Road infrastructure development plays a crucial role in supporting connectivity, mobility, and economic growth. This study analyzes and compares the cost and time aspects of concrete and asphalt pavement construction on the Bendung-Bantengan road segment in Mojokerto Regency. The methods applied include an analysis of average daily traffic (ADT) data, soil California Bearing Ratio (CBR) tests, and regional topography assessments. The asphalt pavement design adheres to the 2017 Manual for Pavement Design (MDPJ), while the concrete pavement design follows the Pd T-14-2003 guidelines. The findings reveal that concrete pavement with a thickness of 25 cm incurs a total cost of IDR 2.49 billion, which is more economical in the long term compared to asphalt pavement costing IDR 3.36 billion. In terms of construction time, concrete pavement requires a shorter duration of 108 days, whereas asphalt pavement takes 120 days to complete. Concrete pavement also demonstrates superior durability and resistance to heavy traffic loads, making it an ideal choice for areas with high traffic intensity and stable soil conditions. Conversely, asphalt pavement, despite its lower initial cost and faster implementation, demands more frequent maintenance, resulting in higher long-term expenses. This study underscores the importance of selecting the appropriate pavement type based on traffic conditions, budget constraints, and project timelines. The findings contribute to more efficient and sustainable road infrastructure planning, offering valuable insights for policymakers and engineers tasked with improving regional connectivity and infrastructure resilience.

Abstract

This research presents a comparative analysis of the cost and construction time between flexible and rigid pavement structures on the Siwalanpanji-Kemiri road section in Sidoarjo Regency, East Java, Indonesia. The area is undergoing a functional shift from rural to industrial, necessitating durable infrastructure to accommodate increasing heavy vehicle traffic. Using the 2024 Indonesian Pavement Design Manual (MDPJ), the research evaluates the technical and economic viability of both pavement types over 20-year and 40-year service lives. Key parameters include Average Daily Traffic (ADT) projections, Cumulative Equivalent Single Axle Load (CESAL), and subgrade strength derived from Dynamic Cone Penetrometer (DCP) tests. These inputs inform pavement thickness designs and cost estimates based on local unit prices (HSPK). Findings reveal that flexible pavement offers faster construction (9 days vs. 39–49 days for rigid) but incurs 38% higher long-term costs due to frequent maintenance. Rigid pavement, despite longer initial construction time, proves more economical over 40 years, with lower maintenance needs and superior durability under heavy loads. Cost analysis shows rigid pavement saves up to IDR 3.5 billion compared to flexible alternatives over four decades. The study also highlights the sustainability benefits of reusing existing materials, aligning with environmental goals. These results provide actionable insights for the Sidoarjo Public Works Agency, emphasizing rigid pavement as the optimal choice for industrializing corridors. The research underscores the importance of life-cycle cost analysis and context-specific design in infrastructure planning, offering a model for similar regions facing rapid urbanization and traffic growth.
