A GIS-Based Method of the Assessment of Spatial Integration of Bike-Sharing Stations

The paper presents a method of the assessment of spatial integration of bike-sharing stations in urban agglomerations based on GIS tools for analyses. The method uses four sub-models: system of bike-sharing stations, road and street network, demand for bike-sharing ridership, bike-sharing ridership routing, and value matrix of spatial integration measures. The presented method allows the identification of different categories of segments of the road and street network used for bike travels and enables the identification of the set of segments that should be upgraded into bike-friendly infrastructure offering bike lanes or cycle paths in order to ensure the appropriate level of spatial integration of bike-sharing stations. The possibility of the application of the method has been studied on the example of the existing bike-sharing system in Katowice, a city in southern Poland. The research presented in the paper has been conducted based on data on bike rentals and bike trips from eight months of 2018. Selected results of the spatial integration assessment of bike-sharing stations, which may be useful for making investment decisions in the bike-sharing system development, are presented.

Evaluating the Utility of Human Readiness Levels (HRLs) with Human System Integration Assessments (HSIAs)

An industry-wide Human Readiness Level (HRL) working group was established to revisit and mature previous work conducted on establishing an HRL scale. A releasable and generalizable set of HRLs, including the questions to be answered at each level and the corresponding exit criteria, has been completed and is currently being verified through a variety of case studies. The objective of this research is to describe the current state of the HRL scale and apply it to a program of record to determine its corresponding HRL based on the findings of its Human System Integration Assessment (HSIA). The HSIA documents potential or known issues that could impede or prevent the users’ ability to operate, maintain, and sustain the system. Three HSIAs for the program are analyzed at different acquisition milestones to determine whether the HRL accurately captures the HSI issues for the developing system.
