“…These results are very decent and highly suitable for improving vehicle awareness and pedestrian safety at the zebra crosswalk level. A previous attempt in using the VLC technology in pedestrian safety applications has been recently reported in [ 53 ]. Nevertheless, in this case, the optical camera visible light communication technology has been used to signal distracted pedestrians using their mobile phones that they are approaching a red traffic light signal.…”

In urban areas, pedestrians are the road users category that is the most exposed to road accident fatalities. In this context, the present article proposes a totally new architecture, which aims to increase the safety of pedestrians on the crosswalk. The first component of the design is a pedestrian detection system, which identifies the user’s presence in the region of the crosswalk and determines the future street crossing action possibility or the presence of a pedestrian engaged in street crossing. The second component of the system is the visible light communications part, which is used to transmit this information toward the approaching vehicles. The proposed architecture has been implemented at a regular scale and experimentally evaluated in outdoor conditions. The experimental results showed a 100% overall pedestrian detection rate. On the other hand, the VLC system showed a communication distance between 5 and 40 m when using a standard LED light crosswalk sign as a VLC emitter, while maintaining a bit error ratio between 10−7 and 10−5. These results demonstrate the fact that the VLC technology is now able to be used in real applications, making the transition from a high potential technology to a confirmed technology. As far as we know, this is the first article presenting such a pedestrian street crossing assistance system.

“…Business is a significant behavioral activity and is related to ecological improvement. In B2C (business-to-consumer), transportation accounts for the largest share of greenhouse gas emissions [63]. As the amount of e-consumers rises, so does interest in sustainability studies that are related to these kinds of transactions, as sustainability remains one of humanity's toughest challenges [64].…”

Defining a Digital System for the Pedestrian Network as a Conceptual Implementation Framework

In cities today, the digitalization of mobility is one of the most crucial tools that link each single mobility service providers (e.g., ride sharing, public transportation, air travel, etc.) to users. Based on the smart pedestrian network model, the purpose of this study is to initially provide the requirements towards the digitalization of a pedestrian network model and subsequently to draft an institutional framework towards the effective implementation and management of pedestrian mobility that will develop/create a pedestrian network as a new structure in the city. The methodology is applied in three phases, with three separate approaches: “desk approach” for a data gathering standard that is knowledge-based and connected to walkability; a “digitalization approach” for citizen and stakeholder participation in policy co-creation; and a “business approach”. A business approach is defined as a set of operations that takes one or more types of input and produces a customer-valued outcome. In this case, customers are citizens and the business approach by applying a digital system is assessing policies and finding/defining an optimized combination of shared applicable/effective policies to implement the pedestrian network. By boosting an innovative linkage of these three phases, digitalization of the pedestrian network has great potential to improve the walkability planning process and therefore to create more sustainable and livable urban spaces.
