“…Another significant conclusion was that macroscale urban structure traits (such as density, mixedness, and connectedness) fit better into TOD requirements in Iranian cities than microscale ones such as streetscape characteristics. The evidence from other developing countries also confirms this; while urban density in the developing world, for example, is higher than its American, Australian, and European counterparts [76,77], design practices are still car-oriented, and pedestrian (social) activities are hindered in most urban environments in developing cities [75], such as using subway bridges and tunnels for pedestrian crossings [77], narrow lanes and lack of parking for cyclists at stations [78], dedicating the whole frontage of houses to vehicle access found in new developments [79], wide streets and large setbacks [80], the dearth of urban design promotions, i.e., streetscape improvement [76] and green areas [81], and poor physical integration of transit nodes with the surrounding environment [80,82,83]. This is important because macro or structural features are even more troublesome to modify than streetscape or street design.…”

The goal of this study was to find out how suitable the existing design of urban forms is for adopting transit-oriented development (TOD) basic ideas. Within a major metropolis and a medium-sized city, three varieties of Iranian urban fabric (historic, transitional, and modern) around transit stations were selected using the case study research technique. Then, for two sizes of station areas (macro) and street scales (micro), several TOD design dimensions were evaluated. The results of the comparative research indicated that Iranian cities offer greater chances for TOD design in inner urban areas (including historical and transitional urban forms), whereas microscale characteristics are less reliant on the kind of urban form.

“…Dodero et al (2014) noted that BRT systems in several cities have begun to experience problems of capacity. Babalik-Sutcliffe and Cengiz (2015) reported that Istanbul's BRT system has attracted mixed opinions regarding its performance, with BRT failing to provide necessary capacity to meet its high demands, and with other design and planning-related issues such as a lack of passing lanes at stations and poor system integration. Some studies have related facility bus capacity to intersection operation (Hidalgo et al 2013) and therefore traffic-based QOS.…”

High volume bus stop upstream average waiting time for working capacity and quality of service

High volume bus facilities range from on-street facilities to dedicated Bus Rapid Transit (BRT) facilities. The aim of this study is to better understand performance by directly relating critical stop bus capacity to quality of service (QOS), which measures performance from the passengers' and operator's perspectives. The US transit capacity and quality of service manual methodology estimates facility bus capacity based on critical stop operation using a failure rate approach. However, this approach is inaccurate under high volume conditions and the failure rate is a difficult measure to prescribe and to interpret. This research provides an improved understanding of operation by instead considering bus upstream average waiting time to measure capacity and QOS performance, because it is experienced directly by passengers and is an indicator of the impact upon general traffic. A fundamental microscopic simulation model is developed with many bus stop operational aspects occurring stochastically, including upstream arrivals. An empirical upstream average waiting time model is calibrated for five bus stop scenarios including BRT and on-street conditions. This is then used to determine working capacity based on QOS threshold upstream average waiting time. Assigning a worse threshold gives diminishing returns in working capacity, particularly for waiting times beyond 60 s. For an assigned threshold, as loading area processing time reduces, working capacity increases more markedly. This demonstrates that BRT stations are more productive than general on-street bus stops. An example shows that a policy decision exists for the operator as to which QOS threshold to accept in balance with working capacity that suits the desired schedule. It is also discussed that the model enables the operator to evaluate the impact of design or operational changes as well as timetable changes on capacity and QOS.
