Background: The high influx of private and public vehicles within global cities (including Ibadan) has resulted in traffic congestion within the city centre. Ibadan North-East, an urban local government area (LGA) within the metropolitan land area of Ibadan, has been experiencing automobile accidents and traffic congestion which in turn limits emergency responders.Objectives: The broad objective of the study was to develop a digital road network database for emergency response to road traffic accident, Ibadan North East, Nigeria.Methods: This study made use of primary and secondary data to generate spatial and non-spatial data. ArcGIS 10.3 was used to create the database, analyse data and display the results. Spatial search and network analysis were carried out using a kernel density estimated tool to generate a black-spot area within Ibadan North-East. Dijkstra’s shortest path algorithm in the ArcGIS Network Analysis was utilised to identify the closest health facility to the road traffic crash scene.Results: The most cost-effective haven introduced route impedance and is defined as the best route. Study findings show that dynamic distance varies from the best route to an alternative route. Also, kernel density estimation reveals that crashes widely occur in the northeastern and southwestern parts of Ibadan North-East (Iwo Road and Orita-Aperin). Incorporating live traffic data using GPS technology and traffic cameras was identified to enhance road traffic data documentation and safety.Conclusion: The study identifies GIS as a decision support system that is useful in the area of planning, mitigation, preparedness, response and recovery for decision-making in road traffic-related emergency management and emergency planning services in Ibadan.

PurposeThis paper sought to uncover the intrinsic determinants of the choice of transport modes in Nigeria's capital city, Abuja, based on commuters' perceptions on different modes of transport. The ultimate goal of the study was to come up with suitable multifaceted measures to deter private car usage, while refocusing society's mind-set towards alternative forms of transport, thereby keying into some transport-related sustainable development goals (SDG) goals.Design/methodology/approachThe study adopted qualitative methods: 320 commuters were surveyed at bus stops and car parks around the city, and respondents were identified using multistage sampling, aided by purposive/convenience sampling, and this number was reached by saturation of themes. Focus group discussions were held with eight screened public officials from relevant (transportation and environment related) agencies/unions in the city. NVivo 10 software was used to thematically analyse the data gathered from a relativist and an interpretive stand point.FindingsThe study found transport mode choice to be intrinsically more motivated by socio-economic forces serving as a basis for other socio-psychological factors. Multifaceted measures, including spatial, socio-economic, environmental and public relation measures, were found suitable to break car-use motives in the study area towards adopting alternative modes of transport, thereby achieving some transport-related SDG targets.Originality/valueThe study was unique as it looked at the intrinsic mode choice determinants from a Sub-Saharan African capital city perspective and provided suitable multifaceted best practiced measures that deemphasised car use while emphasising alternative modes, thereby shifting commuters' mind-set towards environmentally sustainable modes of transport.

Access to potable water and sanitation promotion is critical to public health and community development. The rural communities of Garatu and Gidanmangoro were selected for a comparative investigation of the challenges households faced in accessing water and sanitation facilities. The study used primary data collected through survey questionnaire administration. Findings revealed that many of the respondents are female. In Garatu, 79%, and Gidanmangoro, 56%, have access to boreholes, while no residents of the two communities have access to the pipe water. The results also indicated that only about 17% of respondents have access to a water closet facility. The study revealed that the challenges associated with access to water and sanitation facilities include slow pace of domestic and commercial activities, household children absence or lateness to school, water unaffordability, and social friction and quarrels resulting from the long queue at the water point. It is recommended that attention be placed upon potable water facilities to improve household access in rural communities.
