Impact of visibility on traffic Incidents at signalized intersections –a case study in Polish cities
Archives of TransportIn urban agglomerations, signalized intersections are common. However, in traffic management, safety-focused strategies are often sacrificed for traffic efficiency by allowing simultaneous multiple conflicting movements.

An Initial Investigation of the Effects of a Fully Automated Vehicle Fleet on Geometric Design
Journal of Advanced Transportation, 2019 This paper investigates the potential changes in the geometric design elements in response to a fully autonomous vehicle fleet. When autonomous vehicles completely replace conventional vehicles, the human driver will no longer be a concern.

Three-dimensional stopping sight distance control on passing lanes of divided highways [PDF]
European Transport Research Review, 2016 Stopping Sight Distance control of passing lanes of divided highways represents currently a discussion point among researchers. A 3-D approach to address the issue is accepted as the overall solution to the problem by both researchers and contemporary design policies.

Use of the Safety Factor and Margin of Safety in Motorcyclist Accident Risk Management
International Journal of Technology, 2018 Deceleration rate, time to collision and impact speed have been commonly employed as accident risk indicators. However, it is hard to assess the level of accident risk since these indicators have not been developed with measurable score criteria.

Incorporating vehicle mix in stimulus-response car-following models
Journal of Traffic and Transportation Engineering (English ed. Online), 2016 The objective of this paper is to incorporate vehicle mix in stimulus-response car-following models. Separate models were estimated for acceleration and deceleration responses to account for vehicle mix via both movement state and vehicle type.
