Interstation travel speed is an important indicator of the running state of hybrid Bus Rapid Transit and passenger experience. Due to the influence of road traffic, traffic lights and other factors, the interstation travel speeds are often some kind of multi-peak and it is difficult to use a single distribution to model them. In this paper, a Gaussian mixture model charactizing the interstation travel speed of hybrid BRT under a Bayesian framework is established. The parameters of the model are inferred using the Reversible-Jump Markov Chain Monte Carlo approach (RJMCMC), including the number of model components and the weight, mean and variance of each component. Then the model is applied to Guangzhou BRT, a kind of hybrid BRT. From the results, it can be observed that the model can very effectively describe the heterogeneous speed data among different inter-stations, and provide richer information usually not available from the traditional models, and the model also produces an excellent fit to each multimodal speed distribution curve of the inter-stations. The causes of different speed distribution can be identified through investigating the Internet map of GBRT, they are big road traffic and long traffic lights respectively, which always contribute to a main road crossing. So, the BRT lane should be elevated through the main road to decrease the complexity of the running state.

Mapping Analysis

Fenomena suburbanisasi yang terjadi di kota Makassar mendorong terciptanya pusat-pusat aktivitas baru di kawasan pinggiran dan menimbulkan berbagai masalah baru, seperti masalah transportasi. Penelitian ini menjelaskan arah perkembangan kota di wilayah suburban, karakteristik pergerakan, kondisi pelayanan angkutan massal dan menemukan strategi pengembangan transportasi angkutan massal. Proses pengumpulan data dilakukan melalui observasi lapangan dan wawancara, kemudian dianalisis menggunakan mapping analysis, deskriptif kuantitatif, komparasi dan SWOT untuk menemukan strategi pengembangan. Hasil studi menunjukkan bahwa kota berkembang ke arah  Timur dan Selatan serta tidak sesuai dengan hierarki jalan. Disamping itu masyarakat suburban dominan melakukan perjalanan 5 kali dalam seminggu dengan waktu tempuh berkisar 30 menit. Pelayanan angkutan massal menggunakan bus (Bus Rapid Transit) masih rendah karena halte masih sulit dijangkau meskipun biaya penggunaannya sangat terjangkau dan memberikan kenyamanan lebih dibanding angkutan massal lainnya. Oleh karena itu diperlukan strategi pengembangan konsep transportasi yang bersifat mikro dan adaptif untuk diterapkan.
