“…Second, flatter rural areas often include long stretches of road with few people and high speed traffic. Poor sidewalks and traffic safety might discourage walking 28 29. If older people perceive danger from a poor sidewalk or traffic, they may be less receptive to physical activity such as walking.…”

ObjectivesWe investigated whether a moderate-to-vigorous physical activity (MVPA) level and walking time were associated with a hilly environment in rural Japanese older adults.DesignCross-sectional study.SettingUnnan city, Ohnan and Okinoshima towns in Shimane, Japan.ParticipantsData were collected from 1115 adults from the Shimane CoHRE study, who were aged 60 years and older and living in rural Japan in 2012.MeasuresWe measured the total time spent on MVPA and walking using a Japanese short version of the International Physical Activity Questionnaire. The land slope in 400 or 800 m network buffers was assessed using the geographic information system. A multivariable Poisson regression model examined the prevalence ratios (PR) and 95% CIs of walking time or MVPA levels meeting the WHO guideline (>150 min/week) in the land slope categories (low, middle and high), adjusted for confounders.ResultsEngaging in the recommended level of MVPA was significantly associated with middle land slope (PR=1.07; p=0.03) and high land slope (PR=1.06; p=0.07) compared with low land slope in the 400 m network buffer, as well as with middle land slope (PR=1.02; p=0.48) and high land slope (PR=1.04; p=0.25) compared with the low land slope in the 800 m network buffer. Walking time was significantly associated with middle land slope (PR=1.13; p=0.04) and high land slope (PR=1.17; p=0.01) compared with low land slope in the 400 m network buffer, and with middle land slope (PR=1.09; p=0.16) and high land slope (PR=1.17; p<0.01) compared with low land slope in the 800 m network buffer. The sensitivity analysis found only a positive association between walking time and land slope in the 400 and 800 m network buffers.ConclusionsThis study showed that a hilly environment was positively associated with walking time among older adults living in rural Japan.

“…Determining the network characteristics of structure and function is the key challenge of current research, and the ultimate goal of the network research is to better understand the behaviors of the transport systems [10]. Hence, the research involving the fusion of the two aspects is a more comprehensive research approach [11][12][13][14].…”

“…In the context, the transport dynamics refers to traffic flow, and the built environment is the typical part of the road network structure. Some studies have analyzed the relationship between the built environment and traffic systems, such as traffic behaviors [16][17][18][19][20], the association between network structure and road safety [13,21,22], and the correlation between traffic congestion and different attributes of urban land use [23][24][25]. Though they found strong empirical evidence to show the correlation, limited research has investigated the impact of the built environment on traffic flow or complicated relationships between them at the level of the network.…”

Purpose: This paper aims to determine the urban traffic flow spatiotemporal characteristics and correlation with the built environment using SCATS (Sydney Coordinated Adaptive Traffic System) and POIs (Point of Interests) data of Shenyang, China. Methods: A standard analysis framework based on these data is proposed in the paper. The study analyzes the traffic volume spatiotemporal distributions and built environment influence factors determined by the geographical detector. An improved gravity model using simple structural parameters (lanes number and road length) is proposed to estimate the traffic flows of day and peak hour scales for specific flow ranges. Results: The results show that the peak hours of different intersections and roads are heterogeneous and reveal trip time flexibility. The correlation between peak hour flows and day flows is significant in the multidimensional analysis. Based on the investigation of lanes, more interesting conclusions are found. In this case, when the numbers of lanes of intersections and roads are more than 14 and 4 respectively, the lane resources are wasted to a great extent. There is also a certain correlation between these factors. Proposed gravity model establishes the connection between structure and function of urban roads. Conclusions: Flexible work time and places will be effective methods to reduce traffic congestion. The day flows could be estimated via a traffic survey on peak hour flows, especially in developing cities. The traffic flow mainly concentrates in a relatively small part of city roads. The maximum service traffic volumes exhibit segmentation, we should reconsider the maximum optimal lanes number of intersections and roads under better performance and utilization rate of the network. The effect of lanes number on the service traffic volumes is found to be more significant compared with the other factors. Our conclusions will be helpful for policy-makers and sustainable urban planning.

“…Studies related to sidewalk functionality for the safety of road users have been undertaken by some earlier researchers and, in general, those studies demonstrate well-designed [42,43] and well maintained pedestrian facilities [40,44,45] so that pedestrians can use the sidewalk facility in accordance with its function that will improve the safety of every road users.…”

Planning, Designing and constructing road infrastructure should give priority to the safety and comfort for road users. Ironically, road infrastructure often becomes the cause of traffic accidents. However, such problem can be solved with a profound understanding in the effect of road infrastructure formation elements on the risk of accidents, so that the handling taken can be more efficient. This study aims to (1) review and see the effect of road infrastructure on accidents, (2) provide handling efforts to improve road infrastructure safety. Secondary sources in the form of books and academic journals were reviewed to answer the research objectives above. The results of the study indicated that the elements in road infrastructure formation had significant effect on the risk of traffic accident. Preventing and handling traffic accidents in terms of the road infrastructure can start from planning, designing, constructing, and improving road infrastructure in accordance with prevailing procedures such as Road Safety Audit (RSA) and Road Safety Inspection (RSI). The role of government such as making safety design standard, assuring compliance with these rules, and methods to measure and rate the overall level of safety being achieved is needed in order to improve road safety.
