“…Recently, research [21] into the construction of pedestrian-friendly cities has also been conducted. Some studies also analyzed the effect of walking density on walking [22] and suggested that walking accessibility has an effect on travel decisions [23]. As described above, walking is a transportation method that is always used at the beginning and end of each means despite using various means such as car, train, and air when moving.…”

Worldwide, the population is aging at a gradually increasing speed, due to a decrease in the population and the development of medical facilities and technology. Due to the rapid aging of the population, social infrastructure will also need to be transformed into convenient facilities for the elderly. Walking facilities have been manufactured based on body size measured for general adults. Accordingly, it is necessary to prepare a new design standard suitable for the characteristics of the elderly. It is very difficult to establish standardized values for the elderly because there is a large difference in gait characteristics as well as body size. Therefore, in this study, gait characteristics were measured for the elderly with the standard physique of the elderly in Korea, and the measured gait characteristic variable values were converted into dimensionless numbers to calculate coefficients with more representativeness. The calculated coefficient is expected to be more universally applied and utilized because factors that may affect it depending on the size of the body are removed. When designing a walking facility, the average body size is applied to convert it back into necessary walking attribute information (including units), and this is presented as an example from Korea. It is expected that the presented results can be used to design more suitable and safe pedestrian facilities for an aging society.

“…I n this group of model it is hypothesized that behavior of pedestrians can be determined by their intended velocity, effects of several attractive and repulsive factors and some fluctuations. Social Force Model has been applied to microsimulation of pedestrian traffic to explain accessibility and walkability for the development of sustainable mobility (Gruden et al (2019), Habib et al (2021), Amprasi et al (2020)). Some other models in this group are Magnetic Force Model (Okazaki and Matsushita (1993)) and Centrifugal Force Model (Yu et al (2005)).…”

In this work a microscopic model on pedestrian flow has been proposed. Observed data is used to calibrate and validate the proposed model. The model developed here uses a fuzzy inference system to represent the rules and a force–field structure to represent the repulsive and attractive impacts of objects and goals, respectively in the flow space. The flow space and time are discretized and viewed as discrete quantities. This microscopic model of pedestrian behavior, which essentially models how each pedestrian behaves over time in the flow space, is embedded in a simulation model which is used to simulate situations similar to the ones for which experiments have been done. The results show that the model performs reasonably well.

“…Since most of the people living today already considered those as a necessity more than a want, the immeasurable number of motorized vehicles actively existing has brought a variety of harmful consequences, including road wide traffic congestion, massive fuel consumption, tremendous increase in accident rates, and excessive CO2 emission. The drastic deterioration of the quality of life brought by these occurrences has led civil societies to identify and implement a more sustainable mobility approach [1]. An integral approach, which starts by shifting from car-centric planning to more sustainable-oriented strategies that can provide simultaneous societal, economic, and environmental gains [2].…”

“…Pedestrian Level of Service (PLOS) has been widely used in the prioritization of these improvement modifications as it measures the level of safety and comfort given by a pedestrian facility [4]. Generally, several methodologies are used in evaluating PLOS, specifically depending on the context but mainly focused on the objective calculation of quantitative components including pedestrian flow, pedestrian space, and pedestrian density [1,5]. However, contrary to the improved facilities and infrastructure, it is still a challenge for the transportation industry to encourage people to walk due to inconsistencies and lack of prioritization of the actual needs of the pedestrian system [6].…”

The importance of non-motorized movements, explicitly walking, and its corresponding impact on social, economic, and environmental aspects has always been overlooked due to the convenience brought by motorized vehicles. An automobile-dependent society mirrors the rise and worsening of several transportation problems, such as road-wide traffic congestion, massive fuel consumption, and excessive CO2emissions. In response to these aggravating situations and in support of various national and international calls, the main objective of this study was to extract the significant factors influencing the pedestrian level of service and walkability and to subsequently develop a predictive mathematical model for evaluating pedestrian conditions. Factors influencing the pedestrian level of service and walkability were initially identified through an extensive review and evaluation of existing studies, literature, and other relevant resources. A cause-and-effect analysis was used to develop an Ishikawa Diagram tackling pedestrian performance. The finalized factors were incorporated into the development of the Pedestrian Performance Assessment Questionnaire (PPAQ), which was utilized for data acquisition. Survey responses were then subjected to factor analysis after satisfying several tests for assumptions and suitability to extract the root causes influencing pedestrian performance. The validated root causes were then integrated to form the Pedestrian Performance Audit Tool (PPAT), a tool used in evaluating pedestrian areas in Tarlac City, Philippines. Data was analyzed through ordinal regression analysis to develop the multi-objective pedestrian performance prediction model. Results showed that there are six critical predictors of pedestrian performance unified in the final mathematical model: Pedestrian Space (PS), Official’s Intervention (OI), Ambiance (A), Vibrance (V), Street Vendors (SV), and Trash Bins (TB), and is the most significant contribution of the study. The model's validity was ascertained through a confusion matrix, which resulted in an acceptable rating. The comparison between calculated and perceived values together with the use of odds ratios served as the basis for the interpretation of some of the key results and findings. Finally, recommendations were also presented which can be a basis for the development of sustainable programs and interventions for the improvement of the pedestrian system.
