Investments in public transit infrastructure in Latin America and the Caribbean often aim to reduce spatial and social inequalities by improving accessibility to jobs and other opportunities for vulnerable populations. One of the central goals of Lima’s Bus Rapid Transit (BRT) project was to connect low-income populations living in the peripheries to jobs in the city center, a policy objective that has not yet been evaluated. Building on secondary datasets of employment, household socio-demographics and origin–destination surveys before and after the BRT began operations, this paper examines the contribution of Lima’s BRT system to accessibility to employment in the city, particularly for low-income public transit users. We estimated the effects on potential accessibility to employment, comparing impacts on lower versus higher income populations, and assessed the changes in location-based accessibility to employment before (2004) and after implementation (2012) for treatment and comparison groups. We found that the BRT line reduced travel times for commuters to reach jobs, in comparison with traditional public transport in the city. However, the coverage of the BRT declines in areas with high concentrations of poor populations, limiting the equitability of accessibility improvements. The analysis by socioeconomic sub-groups found positive effects of the BRT system on accessibility for the higher income areas. Relative to the control group, accessibility increased in the 10-km boundary area of the BRT by 0.01, a seven percent increase relative to the treatment baseline accessibility index in the higher socioeconomic (SES) areas of the city. In contrast, in the areas with high concentrations of lower SES populations, the double difference estimate indicated an 11 percent decrease relative to the baseline accessibility index (0.09). We build on case-specific findings and international literature to reflect on policy avenues to include the poor in the mobility benefits of BRT systems. These measures include targeted fare subsidies for low-income groups, fare integration with other forms of public transport that reduce the cost of transfers, and the increase of coverage of the BRT through the integration of stations with non-motorized infrastructure.

Operational Data

This paper assesses the operational data of a public transportation system, using the Bus Rapid Transit in Lagos State as a case study. Demographic data was collected through the administration of questionnaires to the commuters; this was carried out to observe variations in the population of the commuters from different perspectives. Some other categories of data were collected which include boarding and alighting, headway, arrival rate of commuters, waiting time of commuters and travel time data. These data were presented and analysed with MS Excel and Minitab statistical softwares. Results from the boarding and alighting data showed bus stops with high flux of commuters, these were at Ojota, Ketu, Mile 12, Costain, CMS and TBS. Probability distribution charts were prepared to analyze the remaining sets of data. This was carried out to study the distribution and consistency of the data. Coefficients of variation for the data were also estimated to study the variability of the data. From the study, the data followed normal distribution and they were consistent such that they can be used for further analysis of the system. It can be concluded that the distribution depicts the real situation at the study location. Thus, bus stops with high density of commuters should be provided with more buses so as to reduce the waiting time of commuters.

Crossover Method

Bus Rapid Transit is a bus system that is fast, convenient, safe and on time from infrastructure, vehicles, and schedules. As a graph problem, BRT representation in a graph is done by assuming the bus stop as a vertex and the distance between bus stops is an edge. The problem examined in this paper is to find out the path that passes through all the bus stops with the smallest total distance, where the trip starts and ends at the same point, and all bus stops are crossed exactly once. The method used is the Genetic Algorithm, which works using objective and fitness functions, and combines selection, crossover and mutation operators to find the best solution. Using the roulette wheel, OX crossover method and a 0.07 of the probability of mutation, the distance of traverse from and to the departure point after passing all bus stops is 19.66 km or 12.22 miles.

Investments in public transit infrastructure in Latin America and the Caribbean often aim to reduce spatial and social inequalities by improving accessibility to jobs and other opportunities for vulnerable populations. The Metropolitano, Lima’s Bus Rapid Transit (BRT) project had as one of its central goals to connect low-income populations living in the peripheries to jobs in the city center. We examine the contribution of Lima’s BRT system to accessibility to employment in the city, particularly for low-income public transit users. Building on secondary datasets of employment, household socio-demographics and Origin-Destination surveys before and after the BRT began operations, we assess its effects on potential accessibility to employment, comparing impacts amongst lower versus higher income populations. Findings suggest that the BRT line reduced travel times to reach jobs, in comparison with traditional public transport in the city, amongst populations living within walking distance of the system. However, we also find that the coverage of the BRT declines in areas with high concentrations of poor and extreme poor populations, limiting the equitability of the accessibility improvements. We analyze the distributional effects of BRT infrastructure and services, discussing policy avenues that can improve the prospects for BRT system investments to include the poor in their mobility benefits.

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.
