Measurement of functional mobility in multiple sclerosis: A crosswalk between the patient-determined disease steps and the Neuro-QoL Lower Extremity Function—Short Form [PDF]

Multiple Sclerosis Journal - Experimental, Translational and Clinical
Background The Patient-Determined Disease Steps (PDDS) and Neuro-QoL Lower Extremity Function—Short Form (Neuro-QoL LEF-SF) are patient-reported outcome measures used to monitor mobility symptoms in multiple sclerosis (MS).

Quality of pedestrian flow and crosswalk width at signalized intersections

IATSS Research, 2010
Among various pedestrian facilities, signalized crosswalks are the most complex and critical ones. Their geometry and configuration including width, position and angle directly affect the safety, cycle length and resulting delays for all users.

Can a linking crosswalk table be applied to a different population? An independent validation study for a crosswalk between BSI depression and PROMIS depression scales.

PLoS ONE, 2022
A linking procedure establishes a "bridge" between the scores from different patient-reported outcome (PRO) instruments that measure similar constructs. After developing a linking relationship however, it is critical to evaluate whether this relationship

The role of crosswalk-related features on drivers' spatial yielding compliance at signalized midblock crosswalks

Journal of Traffic and Transportation Engineering (English ed. Online), 2022
The drivers' yielding distance to pedestrians at midblock crosswalks affects pedestrians' perceived safety. This distance can be influenced by either crosswalk-related or non-crosswalk.

Analysis of the efficiency of traffic lights turning red in case of exceeding speed limit

Ingeniería e Investigación, 2021
Due to the presence of various traffic calming measures (TCM) and traffic lights in urban areas, the speed of vehicles is maintained low. Nevertheless, a problem arises in the frontier between urban and non-urban areas because drivers must adapt their ...

U-Net Based Road Area Guidance for Crosswalks Detection from Remote Sensing Images

Canadian Journal of Remote Sensing, 2021
Due to the wide distribution of crosswalks over the road nets, the finding of impaired crosswalk marks is usually long-time delayed, which may put crosswalk pedestrians into danger.

CNN-Based Crosswalk Pedestrian Situation Recognition System Using Mask-R-CNN and CDA

Applied Sciences, 2023
Researchers are studying CNN (convolutional neural networks) in various ways for image classification. Sometimes, they must classify two or more objects in an image into different situations according to their location. We developed a new learning method

Hybrid cooperative intersection management for connected automated vehicles and pedestrians

Journal of Intelligent and Connected Vehicles, 2023
Connected Automated Vehicles (CAVs) have drawn much attention in recent years. High reliable automatic technologies can help CAVs to follow given trajectories well. However, safety and efficiency are hard to be ensured since the interactions between CAVs
