Travel Time Index

Travel time reliability (TTR) indices have gained considerable attention for evaluating the quality of traffic infrastructure. Whereas TTR measures have been widely explored using data from stationary sensors with high penetration rates, there is a lack of research on calculating TTR from mobile sensors such as probe vehicle data (PVD) which is characterized by low penetration rates. PVD is a relevant data source for analyzing non-highway routes, as they are often not sufficiently covered by stationary sensors. The paper presents a methodology for analyzing TTR on (sub-)urban and rural routes with sparse PVD as the only data source that could be used by road authorities or traffic planners. Especially in the case of sparse data, spatial and temporal aggregations could have great impact, which are investigated on two levels: first, the width of time of day (TOD) intervals and second, the length of road segments. The spatial and temporal aggregation effects on travel time index (TTI) as prominent TTR measure are analyzed within an exemplary case study including three different routes. TTI patterns are calculated from data of one year grouped by different days-of-week (DOW) groups and the TOD. The case study shows that using well-chosen temporal and spatial aggregations, even with sparse PVD, an in-depth analysis of traffic patterns is possible.

Shoulder pain is one of the most common presentations of musculoskeletal pain with population prevalence of between 7 and 26 %. The most common pathology that affects the shoulder joint is rotator cuff syndrome. The most important aspects in the management of patient with shoulder pain by general practitioner are to ensure an accurate diagnosis and to start the appropriate treatment on time. The main direction of rotator cuff syndrome treatment includes a period of rest from the exacerbating activity and taking nonsteroidal anti-inflammatory drugs. In some cases the use of the NSAIDs is not possible, so we decided to suggest an alternative non-pharmacological method of treatment. We treated a patient with rotator cuff syndrome by injections of autologous plasma into the affected muscles and projections of entheses that were involved in the pathological process. We obtained positive results. The shoulder pain had been reduced, mobility and movement had been improved after a course of autologous plasma injections. In our opinion, it is expedient to consider such treatment of the rotator cuff syndrome both as an additional method and separately in case of impossibility of prescribing the main therapy.

The presence of healthcare facilities is quite essential to provide good healthcare services in a particular area, however, the existence of healthcare facilities is not evenly distributed in Cianjur Regency. This condition leads to the disparities of healthcare facilities across the Cianjur Regency. In this paper, we aim to measure and map the spatial disparities of healthcare facilities using a Two-Step Floating Catchment Analysis (2SFCA). This method can calculate the magnitude of spatial accessibility for healthcare facilities by formulating the travel time threshold and the quality of healthcare facilities across the study area. This research shows the result that the spatial accessibility of healthcare facilities in the Cianjur Regency is not evenly distributed across the districts. The spatial accessibility value resulted from 2SFCA is ranging from 0- 3.97. A low value indicates low spatial accessibility, while a higher value shows good accessibility. The majority of districts in the Cianjur Regency have the spatial accessibility value 0-0.5 (86%). Meanwhile, only a few have the higher value; value 0.5-0.99 as much as 6.6%, 0.99-1.49 as 3.3%, and 3.48-3.97 has a percentage of 3.3%. Also, this analysis results in the cluster of good spatial accessibility in healthcare facilities, namely the Pagelaran District and Cipanas District. Interestingly, the downtown of Cianjur Regency has lower spatial accessibility compared to both areas.

This research investigated the Ride for Free Public Transportation program for seniors in Oakville, Canada. Using a mixed-methods approach, participants were surveyed (n=131) to understand their travel behaviour, and interviewed (n=16) to understand their perspectives towards taking public transportation. While 63% of seniors said that the Ride for Free Transit Program did not impact their travel behaviour, 37% said that it increased their public transit use. The most popular reason for seniors to use public transportation was taking it by themselves. Some interview respondents said that they used public transportation because they would not have to ask others for rides or they did not have access to a car. Seniors suggested that more education of how to use the bus and transfer could increase senior ridership. This research may aid other municipalities considering similar programs, which could help to sustain the independent mobility of seniors.
