Modeling the Assessment of Intersections with Traffic Lights and the Significance Level of the Number of Pedestrians in Microsimulation Models Based on the PTV Vissim Tool

Round 1

Reviewer 1 Report

The article contains a microsimulation analysis of the impact of the number of pedestrians on pedestrian crossings in the case of crossings controlled by traffic lights. The authors used PTV VISSIM to simulate two interconnected intersections. The results consider the ranges in which the number of pedestrians has a significant impact and change the assessment of the entire intersection to the next worse level of freedom of movement. In traffic simulation, it is interesting and important to pay attention to the number of pedestrians in signalized intersections.

However, the authors' study was only conducted with 11 traffic simulations. Two intersections in the city of Gdynia were used for the simulations, and various influencing factors were also analyzed. However, other traffic control strategies should be considered.

Moreover, using only simulations without actual traffic data as validation is not convincing enough for the conclusions.

Dear reviewer,
Thank you very much for taking the time to read our article and comment on it. As authors, we would like to refer to "Moreover, using only simulations without actual traffic data as validation is not convincing enough for the conclusions."
At the very beginning of the second chapter, it was specified that the data came either from measurements or from an intelligent traffic control system - an induction loop that measures traffic in real-time. And based on this data, the model was created and then validated. In addition, the traffic light programs that have been implemented in the model are also real in a fixed-time form.
Kind regards

Reviewer 2 Report

PTV Vissim offers a powerful simulation of the interaction of people with traffic and transport which supports clear decision-making. It similarly informs capacity planning, design concepts, and routing scenarios. The authors use it to prove that pedestrians should be included in the model and its simulation since the number of pedestrians has a direct impact on the obtained measurement results.  However, who is against it (i.e. I do not fully understand, what is the motivation for writing a paper on this topic)? The results obtained seem logical and understandable.

·       Some terms are not presented in the same way in the text, e.g. we can find the occurrence of both „micro-simulation“ and „microsimulation“ - they should have been uniform.

·       Line 59: ...[13,14]in... -> insert a space

·       Line 104: Priority Rules - Has the same task… -> … have the same task…

·       Line 124: explain what the abbreviation GEH means (also concerning Eq. (1))  

·       Lines 127-128: The variables used in Eq. (1) lack physical units.

·       Line 156: explain the HGV abbreviation

·       Some literature sources are referenced using bold (e.g. [1-3], [4], [5], [6], etc.), others by using standard fonts (e.g. [6], [7], [8], etc.) – why?
