Child pedestrians make up 30% of the total number children injured in road traffic EU. They are a particularly vulnerable subgroup because they exhibit specific behavior related to cognitive and physical development, sociodemographic characteristics, environmental conditions. This paper provides an overview research parameters that affect safety conflict zones intersection—crosswalks. The was undertaken targeting available mostly conducted last 10 years all over world, identification...

Traffic congestion in urban areas is a pressing challenge, with roundabouts and signalized intersections offering different operational benefits. This study explores the integration of these two intersection types, focusing on optimal distance between them to ensure efficient traffic flow. Using microsimulations VISSIM, research examines multiple scenarios involving isolated those adjacent intersections, considering variables such as peak-hour volume, flow distribution, spacing. Results...

Modeling the behavior of pedestrians is an important tool in analysis their and consequently ensuring safety pedestrian traffic. Children show specific traffic which related to cognitive development, parameters that affect are very different. The aim this paper develop a model children-pedestrian’s speed at signalized crosswalk. For same set data collected city Osijek—Croatia, two models were developed based on neural network multiple linear regression. In both cases 300 measured children...

The safety of pedestrians in the city depends on numerous factors such as crossing habits (traffic behaviour, traffic culture), infrastructural elements and overall conditions. Among most critical urban areas are those near pedestrian crosswalks with lights. Several studies focus collecting infrastructure data through a combination video recording manual counting and/or administration interviews or surveys. analysed volume, waiting time, risk other influential parameters. literature shows...

Children pedestrians make up 30% of the total number children injured in road traffic EU. Research shows that are more often urban areas, residential areas near schools and parks, at intersections pedestrian crossings. In this study, children’s behavior was analyzed by observation signalized crosswalks. According to same methodology, research conducted three cities two countries (Enna, Italy, Osijek Rijeka, Croatia) with different characteristics. A 900 measurements were analyzed, 300 each...

Smartphones have become an integral part of our everyday lives and keep us busy while doing other primary activities such as driving, cycling or walking in traffic. The problem digital distraction among drivers has been largely addressed, interest is growing also on vulnerable road users well. In fact, high percentages pedestrians cyclists are accustomed to checking their devices moving This research links the presented theme aims investigate extent which form social media app influences...

One of the most common applications microsimulation traffic modeling is an analysis impact construction or reconstruction facilities/infrastructure, as well changes in regulation to observed network, still planning stage. Having mind that functioning transport system influenced by variable human behavior, which is, among other things, territorially and culturally conditioned, model must be calibrated adjusted local characteristics network its users. The method calibration VISSIM model, using...

Pedestrian safety is a well-known issue, such that many road associations emphasize measures to improve this aspect. One of the main conflict points pedestrian crossings, where motorized and non-motorized traffic flows directly interact attention reaction are two elements can strongly influence their safety. Nowadays, these aspects often deviated by use smartphones surf Internet or social media. The aim present study find out (1) whether how intersection typology affects behavior, both in...

The efficacy of the application traffic models depends on a successful process model calibration. Microsimulation have significant number input parameters that can be optimized in calibration process. This paper presents optimization are difficult to measure or unmeasurable real conditions and includes driver’s behavior Wiedemann’s psychophysical car-following model. Using neural networks, were generated for predicting travel time queue used procedure. results comparison five different...

Airtightness plays a significant role in buildings energy efficiency. This paper describes validation of the new model for predicting airtightness values residential units. utilizes neural network prediction and is obtained based on situ measurements at 58 units local Osijek area (Croatia) carried out during 2013. The presents approach to estimations by using 4 corrective factors associated with building envelope elements their properties. was validated field conditions, but independent this...

Walking is the original form of transportation, and pedestrians have always made up a significant share transportation system users. In contrast to motorized traffic, which has move on precisely defined lanes follow strict rules, pedestrian traffic not heavily regulated. Moreover, specific characteristics—in terms size protection—which make them much more vulnerable than drivers. addition, difference in speed between vehicles increases their vulnerability. All these characteristics, together...

Spatial and traffic planning is important in order to achieve a quality, safe, functional, integrated urban environment. Different tools expert models were developed that are aimed at more objective view of the consequences reconstruction different spatial temporal ranges while respecting selection criteria. In this paper we analyze application multi-criteria analysis method when choosing sustainable solutions center small town, case Belišće, Croatia. The goal examine possibility improving...

In this paper, some of the basic information on Ground-Penetrating Radar (GPR), its applications (especially in field civil engineering) and limitations are presented. As a non-destructive technique, GPR is powerful tool for investigation structures structural members, roads, geological layers, archaeological sites many more. The technology based electromagnetic radiation UHF/VHF range (10 MHz to 3 GHz). choice frequency depends intended use, depth size target medium where located. Joined...

Delays belong to standard parameters used for the evaluation of any type intersection and they are taken in level service an intersection. Intersections with shorter delays bring about economical benefits both users community, enable greater efficiency a traffic system, which is becoming significant criterion increasing motorization. The case studies carried out Europe worldwide reveal that roundabouts delay savings if compared other intersections same operational nearly volume. paper shows...

Traffic accident statistics in urban areas, both locally Croatia and at the European level, identify children as a group of vulnerable road users. The analysis parameters that influence interaction child pedestrians other users requires special attention.
