Isolated Intersection

Masalah klasik kondisi lalu-lintas perkotaan adalah sering timbulnya kemacetan (jam), antrian (queue), penurunan kapasitas simpang (drop capacity) dan waktu tunggu (delay time) yang lama saat melewati persimpangan. Keberhasilan dalam menangani suatu persimpangan akan menjadikan tolok ukur guna mengevaluasi kinerja simpang (intersection performance). Kenyataan yang terjadi dilapangan pengaturan sinyal lalu-lintas (traffic light) seringkali dilakukan dengan melibatkan berdasarkan variabel yang bersifat numerik atau kuantitatif, padahal variabel yang bersifat linguistik atau kualitatif sering diabaikan dan ada kecenderungan tidak pernah dipertimbangkan. Ternyata penggunaan model fuzzy logic dapat memberikan kontribusi cukup besar dalam menangani kondisi persimpangan bersinyal, terutama pada penelitian ini dievaluasi terhadap waktu sinyal tetap (fixed time signal) dan simpang yang terisolasi (isolated intersection), karena dapat melibatkan analisa kombinasi variabel numerik dan linguistik. Hasil review dan penelaahan secara the state of the art dari beberapa penelitian terdahulu, diharapkan akan menjadi terobosan baru untuk memberikan solusi terbaik bagi pengaturan sinyal lalu-lintas, khususnya simpang terisolasi yang berada di Indonesia.

Phase Optimization

A semi-fuzzy logic signal optimization model is proposed aimed at the current frequently oversaturated situation of urban intersections. The model consists of two modules, namely phase optimization module and green time extender module. The phase optimization module is to choose the optimal phase by taking intersection through efficiency and vehicle delay into consideration. The green time extender module determines whether to extend or terminate the current phase green time using improved fuzzy logic control method. The real-time traffic condition on all lanes that enter the intersection are input parameters of signal timing in the whole signal optimization process, so it can make adaptive adjustments about signal timing according to the change of real-time traffic condition, which make it sure that the traffic on all lanes can cross the intersection orderly in the most reasonable phase within the most appropriate green time.
