| Summary: | Pengangkutan utama di Semenanjung Malaysia terdiri daripada pengangkutan awam seperti bas dan kereta api dan pengangkutan persendirian seperti kereta dan motorsikal. Pembebasan karbon dioksida (CO2) dan oksida sulfur(SOX) berubah –ubah secara langsung dengan penggunaan bahan bakar. Pembebasan karbon monoksida (CO), oksida nitrogen (NOX), zarahan halus dan hidrokarbon berubah-ubah berdasarkan reka cipta engin, nisbah udara ke bahan bakar, dan ciri – ciri operasi kenderaan dengan kelajuan optimum melebihi 60 Kilometer per jam. Di persimpangan bersignal, jumlah pembebasan pencemaran lalu lintas bergantung pada empat kitaran mod memandu yang terdiri daripada unsur berhenti dan menunggu di persimpangan lampu isyarat, pecutan, nyahpecutan halaju kenderaan, dan masa yang digunakan oleh kenderaan untuk tidak bergerak bagi keadaan lalulintas tertentu diwakili oleh arus lalu lintas dan geometri persimpangan. Simpang bersignal yang direka bentuk mengikut piawaian yang ditetapkan akan dapatmeminumkan kelewatan dan mengoptimumkan kapasiti persimpangan sedangkan rekabentuk geometri yang tidak tepat akan meningkatkan kelewatan yang dihadapi oleh pengguna jalan raya.
The transportation in Peninsular Malaysia includes public transport such as buses and trains and private transport such as motorcycles and cars. The emissions of Carbon Dioxide (CO2) and Oxides of Sulphur (SOX) vary directly with fuel consumption. The emissions of Carbon Monoxide (CO), Oxides Of Nitrogen (NOX), Particulate Matter and Hydrocarbons vary in addition with the engine design, the air-to-fuel ratio, and vehicle operating characteristics, with an optimum speed usually in excess of 60 kilometres (km) per hour. At the signalized intersection, the amount of traffic emission are depend on the four mode elemental driving cycle consisting of cruise, acceleration, deceleration and idling time for specific traffic condition represented by traffic flow, traffic control and intersection geometry. The signalized intersection that designed according to the proper standard will minimize delay and optimize the junction capacity while the improper design geometry will increase the delay faced by road users. SIDRA Intersection 5.1 software was used in this study in order to investigate the vehicles emissions due to traffic volume and its delay time and the effect of traffic light junction’s configuration during peak hour. There are six signalized intersection along the major road of Jalan Taiping and Jalan Abdul Raof in Parit Buntar will be investigated. The vehicles emission pollution that carried out for year 2010 were generated and compared with the current study in year 2011. Some improvement was proposed in this study in term of coordination between adjacent signal light controllers, left turn on red movement, providing proper signal phasing and signal time and minor geometrical modifications at the chosen signalized intersections. |
