Analysis of Bus-stops locations using Geographic Information System in Ibadan North L.G.A Nigeria

This study focuses on the determination of best location for bus stops  to enhance public transport in Ibadan north, Oyo State.The significance of having suitable locations for Bus stop is recognised as a crucial element in the drive to improve the quality of bus services and public transport in general.This study employs the tools of Geographic Information System (GIS) in the determination of the suitability of the bus stops location, stop spacing and the evaluation of characteristics of the existing stops in the study area. The major roads and bus stops in Ibadan North Local Government were identified and the roads were digitized as line features. Garmin 12 Global Positioning System Receiver (GPS) was used to get the locations of the bus stop. The GPS was calibrated to Geographic Coordinate System (GCS) and World Geodetic System 84 (wgs84) as the datum. For this study, determination of best locations for the bus stop is based on three (3) criteria; these are four hundred (400) meters bus stop interval on the major road, available setback from the road ideal for bus Stop shelter and slope. Thereafter, poorly located bus stops were identified by adding the existing bus stop layer on the suitability map derived from determination of best locations for the bus stops. In all, seventy two (72) existing bus stops were identified, using the stated criteria for classifying the already existing bus stops. The analysis showed that there are four (4) very good bus stops, thirty five (35) good bus stops and thirty three (33) bad bus stops. The paper recommends that guidelines for locating stops should be followed to reduce the risk, accessibility to stops should be considered by standard spacing and by considering marginal walking distance. The conclusion was that giving bus stops location a thorough consideration would help in a long way in enhancing public transport system by boosting the principle of good access which is Safety, Affordability, Accessibility and Reliability.

The Utility of Geographic Information System GIS in Transport Data Integration for Economic Development : Evidence from Ibadan, Nigeria

This study sets out to assess the capability of Geographic Information System GIS in Transport Data Integration for Economic development in Ibadan Nigeria The study entails an analysis of transport data need and an assessment of their relevance in economic planning This need is set against the background of large body of data involved in transportation planning and management The Methodology entails some processes such as data integration data standardization and spatial referencing and interfacing The study shows the importance of referencing of socio-economic data and location referencing in economic planning to assist in economic development Arc GIS programme is employed for integrating data such as demand data i e demographic data land use data economic data and travel supply data such as road networks and related facilitie

Performance Evaluation of Nigerian Ports: Pre and Post Concession Eras

This paper x-rays the performance of the Nigerian ports at two points in time; that is, from 1956-2005 as pre concession era and 2006-2012 as post concession era. It highlights the challenges that undermine the capacity of the sector from meeting up with the global best practices. The data on cargo movement were derived from the Nigerian Port Authority Annual Reports. The study relied on descriptive statistics, trend analysis, chi-square analysis and port performance indicators such as indicator of output and indicator of service in explaining the trend of port performance for the periods under review. The trend analysis employed to explain the trend of cargo movements in all the ports in Nigeria was the Quarterly Moving Averages. It was revealed that the trend of cargo throughput in Nigeria is determined by the inward cargo movement. The analysis also revealed a fluctuation in cargo movement from 1956 to 2005 while the cargo throughput continues to increase unabated from 2006 to 2012. The concession of the port must have been responsible for this upward movement in cargo trend. There was a remarkable increase in inward and outward cargo movement during the post concession era in comparison to the pre concession era.      This paper recommends that government encourages public ownership and private sector operations of the port infrastructure in Nigeria.

Traffic Management Problems in Lagos: A Focus on Alaba International Market Road, Ojo, Lagos State Nigeria

This study examines the traffic management problems resulting from traffic congestion in the study area. It also evaluates the opinion of the stakeholders in the transport sector such as the commuters, transport operators and private car owners on the traffic situations and management problems in the study area. The study depended upon the survey research technique to gather relevant data on the respondents, using the questionnaire as the research instrument. The research identified inter alia the traffic congestion causative factors as; over dependency on small occupancy vehicles, narrow road, indiscriminate parking, loading and off-loading of goods and passengers on the road, on-street trading, inability of the  traffic management agencies to evacuate crashed or breakdown vehicles on time and ineffective traffic control measure. The study recommends the expansion of the narrow road capacity to double lanes, provision of adequate parking facilities, increasing the number of the few bus terminal along the road, provision of adequate park and ride space, prohibition of on-street parking, effective traffic management techniques, pedestrians priority scheme, provision of mass transit buses, provision of more road furniture like traffic light, lane marking, frequent road assessment and maintenance in the study area.
