Abstract

Global climate change has prompted the Government of the Republic of Indonesia to commit to an active role and participation in the attempt of reducing Greenhouse Gas (GRK) emission through a national action program. One of the biggest sectors contributing in the production of GRK is transportation. Meanwhile, the condition of roads also affect the speed of vehicles. This study analyzed the relationship between road condition and travel speed, and the resulting CO2 emission. This research was conducted by taking some class III roads in Brebes as samples. The stages of this study include assessing the road condition by using the PCI method, calculating the average speed of vehicle on each sample road, and from the data of travel speed, the value of CO2 emission was then calculated using IPCC method. The result of this study indicated that the road condition is the factor that affects the travel speed. Increasing the value of PCI by 10 points from the lowest value will reduce CO2 emissions by 3.36% for gasoline-fueled vehicles. This research suggests improving the road condition in Brebes district in order to support Local Action Plan for Greenhouse Gas Emissions Reduction.

Highlights

Global climate change has prompted the Government of Republic of Indonesia to commit to an active role and participation in the attempt of reducing Greenhouse Gas (GRK) emission through a national action program
The stages of this research are: assessing road condition using the Pavement Condition Index method (PCI), calculating the fuel consumption of each type of vehicle from the survey results using the equation of Pacific Consultant International (PCI) with the speed of travel as the variable, and calculating CO2 emissions using the equation from International Panel on Climate Change (IPCC)
Road damage data observed include the type of damage, severity, and dimension of damage that are calculated to obtain the Deduct Velue (DV) and determine the value of Corrected Deduct Value (CDV), the PCI value is obtained by subtracting 100 by the total CDV

Summary

Introduction

Global climate change has prompted the Government of Republic of Indonesia to commit to an active role and participation in the attempt of reducing Greenhouse Gas (GRK) emission through a national action program. One of the biggest sectors contributing in the production of GRK is transportation. The provincial government of Central Java is targeting 12.5% CO2 emission reduction from the transportation sector [1]. Emission from road sectors have contributed a large proportion as compared with non-road sectors (railway) [2]. The increasing number of motor vehicles has lead to an increase of fuel consumption. Increasing fuel consumption required in the combustion process of the engine, will certainly have an impact on increasing levels of exhaust emissions [3]
