Road Safety Audit

This project uses a practical procedure for conducting in-service road safety reviews of existing intersections. The procedure in this project is based on current experience in Canada and other countries and applies road safety engineering research to the Canadian environment. An in-service road safety review is an in-depth engineering study of an existing road using road safety priniciples with the aim of identifying cost-effective countermeasures that would improve road safety and operations for all road users. A review can be done for any road section, intersection, or interchange, and is generally most effective when conducted at locations where a high collision risk has been identified. In-service reviews typically include a structured review of collision history, geometric characteristics, and traffic, operational efficiency and could also include traffic conflict observations and a human factors assessment. The main output from in-service road safety reviews is the identification of road safety problems and the development of cost-effective countermeasures to overcome these road safety problems.

The Impact

The Safe System (SS) approach to road safety emphasizes safety-by-design through ensuring safe vehicles, road networks, and road users. With a strong motivation from the World Health Organization (WHO), this approach is increasingly adopted worldwide. Considerations in SS, however, are made for the medium-to-long term. Our interest in this work is to complement the approach with a short-to-medium term dynamic assessment of road safety. Toward this end, we introduce a novel, cost-effective Internet of Things (IoT) architecture that facilitates the realization of a robust and dynamic computational core in assessing the safety of a road network and its elements. In doing so, we introduce a new, meaningful, and scalable metric for assessing road safety. We also showcase the use of machine learning in the design of the metric computation core through a novel application of Hidden Markov Models (HMMs). Finally, the impact of the proposed architecture is demonstrated through an application to safety-based route planning.

Preferential bus lanes are a widely use strategy to promote travelers to use public transport instead of private cars. Considering its relevance in the urban transportation planning and operation, it is crucial to evaluate them in terms of the operation and safety externality. We performed a road safety assessment in preferential public transport lanes with complex driving environment using a preventive approach on the 7 th Avenue, in Bogota (Colombia), between 39 th Street and 45 th Street. A detailed study of traffic conflicts was carried out under the guidelines of the Swedish technique, which uses the Time to accident and Conflicting speed to establish the severity of a conflict. A traffic conflict is defined as an incident where, if two road users on collision course maintain their speed and trajectory constant, the crash between them will be imminent. With the field information, we calibrated a VISSIM microsimulation model that correctly replicates its traffic operation. Using the SSAM tool, we validated the base model to identify the simulated traffic conflicts in VISSIM and compared them with the observed conflicts. Under the calibrated environment, we developed and assessed three different scenarios of countermeasures to reduce the number of conflicts observed. As a result, we found that the safest scenario is the one established in the regulations that normalize the operation in preferential lanes, currently not obeyed by most users. Based on our results, we recommend an adjustment in the normative measures, including regulating the stopping time and stopping zones of private vehicles and taxis.

Road Safety Audit

Practical tools for improving transportation safety are needed worldwide. It has been estimated that motor vehicle–related crashes account for more than 1 million fatalities each year, and the number of serious injuries far exceeds fatalities. Local and low-volume roads are significantly overrepresented in crash statistics. Globally, the road safety audit (RSA) concept has been recognized as an effective tool in identifying and reducing the crash potential of roadways when used to analyze the safety aspects of project plans and designs before completion. In the local rural road arena, many safety issues are associated with existing roadway networks. Many of these networks have developed over time with little or no planning or design. There is a critical need for a practical tool that focuses on the safety of the existing as-built local road network. The RSA review (RSAR) process has been developed for this purpose, giving specific recognition to the functionality of the road being evaluated for safety issues. Significant numbers of safety improvements are needed, and practical approaches to address these needs are crucial. The RSAR tool has the potential to be particularly beneficial to local governments in systematically addressing safety deficiencies on existing rural road networks. In addition, it is a proactive safety tool that has the potential to protect agencies from tort liability since it establishes a record of the organization’s safety agenda. An RSAR methodology that can be adapted by local agencies is presented. A case study illustrating the application of this process is included. Also highlighted is a local rural training program that has been presented in several states for county applications. The focus is on U.S. county applications, but it is recognized that the process has utility for other agencies and has application in other countries. The necessity for training as a key component in the development of a sustainable safety program is emphasized.

Road Safety Audit

Abstract Transportation has been instrumental in the growth of cultures since the dawn of time, allowing individuals to migrate and goods to be transported. A poorly aligned road not only creates a possible traffic threat but also increases commuting costs and puts a burden on drivers and travellers. As a result, careful decisions are critical in highway construction, both in terms of current needs and the potential growth of the region. A Road Safety Audit is a critical technique for paying detailed attention to road safety during the planning, construction, and maintenance phases of a road. The two key techniques in road safety work are accident reduction and accident prevention. This study focuses on both aspects. The road chosen in this study is another District Road in Bareilly District, Uttar Pradesh. It originates from Fatehganj Paschmi near NH-530 and merges with SH-37 at Baheri. Road Safety Audit is conducted on the road section before opening it to the traffic. This is a two-lane road without a paved shoulder in which Bareilly-Shahi Road also merges from the side at Chainage km 3+400. It has a Major Junction at Chainage km 10+000 which is densely populated Shahi Village. This study is about the road safety measures adopted on the newly built Bhitoura-Shahi-Shergarh-Baheri road and identifies any flaws that could result in an accident or pose a safety risk to road users. It is constructed to liberate people from traffic congestion. During the day, there is a lot of traffic on the road. On the basis of primary and secondary data collection, a systematic analysis of the road section is carried out. The methodology used entails gathering primary data performing a physical survey (inventory) and analyzing the observations, and secondary data from the appropriate authorities. Various recommendations to improve the deficiencies in order to ensure safe and efficient mobility are suggested as per IRC. The plants and tree along the road sides although control pollution of vehicles yet sometimes their branches have to be cut to reduce accidents.

Low- and Middle-Income Countries suffer the large majority (93%) of global road crash deaths and face particular challenges in managing this crisis. This paper presents global data and trends revealing underlying features of the problem for LMICs. LMICs are commonly grouped and described together in road safety commentaries, yet appreciation of the substantial differences between LICs and MICs is vital. While global deaths per 100,000 people have stabilized during the UN Decade of Road Safety, the population rate has increased in LICs (by 8.2%), while decreasing in HIC and MIC. LICs have less resources to address road safety and younger populations adding to risk. Wide variations on road safety performance exist within country income groups, with some of this variance occurring systematically between regions. Absolute numbers of deaths are increasing due to increasing population and increasing vehicle fleets in LMICs compared with HICs. The capacity of MICs, and especially LICs, to manage road safety is hampered by poor crash data to guide action as well less available funding and resources to achieve safer road engineering, safer vehicles, and protect the large proportions of vulnerable road users. Road crash deaths and injuries are retarding the economic growth of LMICs and investing road safety is a costeffective means by which LMICs can move towards becoming HICs. Vital opportunities for cost-effective savings of lives and debilitating injuries in LMICs include better management of speed (especially through infrastructure), improving safety infrastructure for pedestrians, increasing seatbelt use, and shifting travel from motorcycles to buses through provision of Bus Rapid Transit systems.

The Impact

The key role in the implementation of the state transport strategy is played by the development of transport infrastructure, the most important component of which is the road network. The compliance of highways with the requirements of modern traffic flows determines not only the efficiency of industry and agriculture, but also ensuring the proper standard of living of people and the state defense capability. Problems of efficient functioning of public roads, urban roads and streets of Ukraine are outlined. The main provisions for the road safety audit are outlined. Road safety audits are proven to be one of the most effective engineering tools that affect road safety. The main benefit of road safety audit is the detailed assessment of the road safety design solutions at all stages of design. The purpose of a road safety audit is to answer the following questions: - what road elements could pose a threat to road users: to what extent, to what road users and under what circumstances; - what opportunities exist to eliminate or reduce the impact of identified threats on traffic safety. The earlier an audit is carried out in the design and construction processes, the better and more useful the results are. Carrying out an audit in the early stages can help eliminate problems early and, as a consequence, minimize the time and cost of redesigning in the subsequent stages. In addition, it should be noted that conducting an audit leads to intensive negotiations between the auditors, the customer and the designer. Such negotiations are useful for raising awareness of all stakeholders, as well as for improving day-to-day work, design procedures and will be useful for updating building standards or norms. The questions of improvement of methods of calculation of safe speed of movement, development of algorithms of multivariate analysis of conditions of movement, identification of potentially dangerous sites and identification of causes of danger are considered. A mechanism is provided that can significantly accelerate such an audit, effectively utilize human, time and financial resources.

Road Safety Audit

Road Safety Audit (RSA) is a formal procedure for assessing accident potential and safety performance of new and existing roads. RSA is an efficient, cost effective and proactive approach to improve safety of the road users with leading to any trend of accidents and their impacts. RSA appears to be an ideal tool for improving road safety in India, as basic and accurate data on accidents have yet to be collected in a scientific way as well as in a systematic method. It is evident from the traffic composition for the countries like India, where heterogeneous traffic with varying vehicle types differing in their vehicle static and dynamic characteristics. The project stretch considered is NH-69 (Bhadhravathi to Shivamogga – Karnataka State) ranging 22.1 Kms. The present study deals with road inventory, signage inventory, traffic volume count survey, spot speed study, Speed and delay study and other surveys such as topographic survey and Accident data has been collected for the stretch for a period of 2012-16 is collected and analysis is carried out. The study aims to evaluate Road Safety Audit of a section of four-lane National Highway (NH)-69 and will focus on evaluating the benefits of the proposed actions that have emanated from deficiencies identified through the audit process. Missing road and median markings to be done and speed signs should match with speed. Access and service lanes are also deficient which requires immediate improvement.
