Traffic crashes are one of the main reasons for the deaths of many people and the loss of property. Road safety is a crucial aspect of transportation that aims to prevent crashes and injuries on the road, and several contributing factors affect it. In this study, the binary probit model using the N-Logit software was applied to crash-related data to examine the contribution of several variables to severe crash outcomes in Al-Diwaniyah City. Crash severity (the dependent variable) in this study is a dichotomous variable with two categories, severe and non-severe. Because of the binary nature of this dependent variable, a binary probit model was found suitable. Out of 37 independent variables obtained from Al-Diwaniyah Hospital traffic crash reports between 2014 and 2021 and from fieldwork to evaluate the pavement surface condition using the pavement condition index (PCI), six were statistically significantly associated with severe crashes. These factors include driver age, spring and summer seasons, pavement surface conditions, pedestrian collisions, and multi-vehicle crashes. Some proposals were also recommended to reduce traffic crashes, such as using median barriers to regulate pedestrian crossing, managing a proper number of lanes in the roads to avoid congestion due to a large number of vehicles, assessing the condition of the pavement surface annually at least, to identify pavement defects and conduct appropriate maintenance. Therefore, governments and transportation agencies must prioritize regular pavement condition evaluation as part of their maintenance programs for roads and highways. In conclusion, road safety is a complex issue that requires a multi-faceted approach involving various stakeholders such as government agencies, law enforcement agencies, vehicle manufacturers, drivers, pedestrians, and other road users.

“…To account for unobserved effect (see Mannering, Shankar, and Bhat (2016)), a random parameter binary probit with heterogeneity in means and variance (RPMHMV) was adopted. See Tay (2015) and Zubaidi, Obaid, Alnedawi, and Das (2021) for binary probit modelling with random parameters and see Seraneeprakarn et al (2017) and Se, Champahom, Jomnonkwao, Karoonsoontawon, and Ratanavaraha (2021) for how to allow explanatory variables to influence means and variances of random parameters. This study used the simulated maximum likelihood estimation with 200 Halton draws.…”

The 2022 Australasian Road Safety Conference, was held in conjunction with Trafinz NZ. With the restrictions of the COVID-19 pandemic mainly behind, the organising committee were pleased to present the proceedings for the first hybrid format for this conference. Conference attendees were able to attend in person (at the Te Pae conference centre in Ōtautahi Christchurch) or virtually, including live streamed plenary sessions. This is the seventh conference in the series that commenced with amalgamation of the Road Safety Research and Education Conference and the Australasian College of Road Safety Conference. It is the first time the combined conference has been in New Zealand. This conference was a unique opportunity for everyone involved in road safety including researchers, practitioners, policymakers, police, educators, advocates and community groups to meet, present and discuss their work. These proceedings describe research, educational and policing program implementation and policy and management strategies related to all aspects of road safety and especially related to the conference theme of Changing Today for Tomorrow. Over 600 delegates from 18 countries will be attending the hybrid conference. This conference covered a comprehensive range of topics including speed, infrastructure and road design, education, licensing, vehicle design, impairment due to alcohol, drugs and mobile phones. The conference plenaries also covered the impacts of climate change on future transport systems and how this might impact on road safety. There was also a special plenary session on safety issues for Indigenous people groups across New Zealand and Australia and how we can work with these communities to achieve vision zero. The conference also presented both face-to-face and virtual symposium sessions including the following important topics: Integrating road safety into local Government, Automated Enforcement, Implementing Speed Management in Victoria and New Zealand, Gig economy road safety, Changing the way we think about older Australian drivers, Managing the safety of ageing heavy vehicle drivers, How safe is your dinner and Redeveloping Bike Education. Authors of accepted Extended Abstracts and Full Papers represent international and local institutions from all aspects of their respective communities including research centres, private companies, government agencies and community groups. These Extended Abstracts provide an indication of the important work being done in Australia, New Zealand and internationally as part of the United Nations, One UN Vision for Road Safety to reduce the number of crashes on the road by 50 percent by 2030. The Conference Organising Committee allowed two manuscript types for the conference: ‘Extended Abstracts’ and peer-reviewed ‘Full Papers’. Using a similar format to the previous successful conference in 2021, the Conference Scientific sub-Committee initially called for submissions in the form of Extended Abstracts (approx. 1 to 3 pages). Each Extended Abstract was reviewed by two independent expert peer reviewers on the following selection criteria: content consistent with the conference theme, novelty of information or data, clarity, relevance to practice or policy, scientific merit, and interest to audience. Over 200 Extended Abstract manuscripts were accepted for face-to-face (F2F), virtual (around 80) and poster sessions. To accommodate more presentations into the four F2F conference streams some authors were offered a rapid-fire presentation slot of 4 minutes, with the option to provide a longer virtual presentation or poster. Authors were also provided the option of submitting a Full Paper, which is HERDC* compliant. Based on the outcome of the peer review of their Extended Abstract, some authors who requested extension of their submissions into Full Papers for a run on into the Journal of Road Safety, were provided that opportunity by the two peer reviewers. The submitted Full Paper subsequently underwent a further review by three independent peer reviewers for inclusion into the Journal of Road Safety (JRS). There were a record number of Full Paper submissions of which nine of twenty four submitted have so far been fully peer-reviewed and accepted as ‘In-Press’ submissions for publication in the JRS. DOI links to these full papers are included into these proceedings. For the second time in the conference series the ACRS2022 partnered with Monash University’s Monash Art, Design and Architecture (MADA) to link Poster authors with final year graphic design students and alumni. Like at the ARSC2021 this gave authors an opportunity to develop high quality visual communications of their poster content. The Authors who chose this option that were matched with a MADA graphic design student and successfully completed the Poster, have had their Poster attached to their Extended Abstract pdfs in these proceedings. The Poster authors were also provided a 4 minute oral rapid-fire presentation slot in a concurrent podium session, followed by a 30 minute poster session, where attendees could ask questions.

“…Al-Askari District ranked first in the number of crashes with 707 traffic crashes, followed by Al-Urouba District with 379 traffic crashes, Al-Wahda District with 271 traffic crashes, Al-Jamhouri District with 235 traffic crashes, Al-Jazaer District with 212 traffic crashes. Therefore, it is important to evaluate the condition of pavement in these Districts where the number of traffic crashes is high to know the effect of pavement defects on the accident rate [12] [13] [14]. other road information such as the number of lanes, the presence of medians, and street width was collected to study their effect on the condition of the pavement and the number of crashes.…”

Roads and transportation infrastructure are critical assets for supporting political stability as well as economic and sustainable expansion in developing countries. Yet, pavement maintenance backlogs and the high capital expenditures of road rehabilitation need the adoption of pavement evaluation methods to ensure the best value for the investment. road maintenance is considered one of the main factors for preserving the road structurally and functionally, and before carrying out maintenance, pavement defects must be identified by evaluating the condition of the pavement to perform the appropriate maintenance. In this study, the Pavement Condition Index (PCI) method was relied upon to evaluate roads in Al-Diwaniyah City. Where several data were collected for the study, including the number of crashes for each region, the number of lanes, street width, the presence of a median, and the pavement condition evaluated for the regions with the highest crash rate, which are Al-Askari District with 707 crashes, Al-Urouba District with 379 crashes, Al-Wahda District with 271 crashes, Al-Jamhouri District with 235 crashes, and Al-Jazaer District with 212 crashes. This study is considered the first study to evaluate roads in Al-Diwaniyah city. The results of the study showed that the condition of the roads ranged from poor to satisfactory and there is no road reach to serious and failed. The results showed that the worst road is Al-Askari District, which lacks a lot of maintenance, at a rate of PCI 52.1. It is followed by Al-Wahda District with a PCI rate of 57.6, Al-Jamhouri District with a PCI rate of 67.2, Al-Urouba District with a PCI rate of 70.7, and Al-Jazaer District with a PCI rate of 73.7. The deterioration of the pavement surface condition affects the rash rate, and it is more dangerous when it is correlated to other road factors. Additionally, it was noted that the most prominent defects in the pavement surface of the five evaluated roads are: potholes, rutting, longitudinal and transverse cracks, corrugation, patching, raveling, depressions, and alligator cracks. The study recommended conducting more research on evaluating more roads in Al-Diwaniyah City on an annual basis and conducting periodic maintenance in order to improve the status of this city, which suffers from neglect in all respects, measures must be taken to enhance the environment and economy, sustain the streets, reduce maintenance costs, ensure traffic safety, and protect the lives of citizens.
