摘要

该研究的目的是通过分析内陆水道的趋势和事故概率来比较尼日利亚和加纳撒哈拉以南非洲城市的机动性和可达性,以提高安全标准。通过结构化数据和对船只和渡轮运营商的访谈,使用了来自100名受访者的主要数据。根据所选路线的平均事故概率(以百分比为单位),将回答分为四个等级:非常安全{0-20},非常安全{21- 50},不安全{51- 80}和非常不安全{81- 100}。来自国家内河航道管理局(NIWA)、加纳海事管理局(GMA)和沃尔特湖运输公司(VLTC)的二手数据进行了概率、百分比和趋势分析。结果表明,在尼日尔三角洲,每次旅行发生致命事故的可能性约为59%;而在沃尔特湖上,发生致命事故的可能性为7%。在尼日尔三角洲的阿夸-伊博姆路线上,交通的趋势非常明显。跨越河流和河流州。在集市日,在Yeji、Tapa Abo和Bidi路线上的Volta Lake记录了高交通量,而在非集市日,Makango路线上。Kwamekrom和Kpechu的客运量很高。据估计,尼日尔三角洲航线的年客运量与沃尔特湖航线的年客运量之比为4:1。进一步的安全分析表明,河流州的Harcourt港水路是不安全的,而Volta湖的水路是相对安全的,其平均概率比为8:1。对数线性回归分析显示,尼日利亚哈科特港和加纳沃尔塔湖所选航线的船舶运输需求价格弹性分别为1.00和0.97。它进一步支持这样一个事实,即尼日利亚比加纳更多的乘客对水路旅行有反应。研究结果表明,尼日尔三角洲流域的水道风险指数和事故发生可能性高于沃尔特盆地;并建议VLTC和NIWA应进行最佳投资,并与私营部门合作,执行和规范水路运营,以提高水路用户的安全性和机动性。

Trend of traffic on inland waterways of Port Harcourt urban coastal environment: a comparative safety imperative for a Ghanaian coastal regional province
The purpose of the study is to compare mobility and access in Sub- Saharan Africa urban cities of Nigeria and Ghana by analysing trends and accident probabilities on the inland waterways to improve safety standards. Primary data from100 respondents through structured data and interview from boat and ferry operators were used. The responses were ranked on a four-point scale based on the selected routes’ average accident probabilities in percent: Very Safe {0-20}, Fairy Safe {21- 50}, Unsafe {51- 80}, and Very Unsafe {81- 100}. Secondary data from the National Inland Waterways Authority (NIWA) and Ghana Maritime Authority (GMA) and the Volta Lake Transport Company (VLTC) were subjected to probability, percentage and trend analysis. Results indicate that in the Niger delta for every journey there is approximately 59% likelihood of fatal accident; while on the Volta Lake there is a likelihood of 7% fatal accident occurrence. The trend of traffic was high in the Niger delta noticeably in the routes of Akwa- Ibom. Cross Rivers and Rivers State. The Volta Lake recorded high traffic volumes on the routes of Yeji,Tapa Abo and Bidi on market days while on non-market days, Makango. Kwamekrom and Kpechu had high passenger volumes. Estimated annual passenger traffic on the Niger delta routes outweighed that on the Volta Lake routes on a ratio of 4:1. Safety analysis further reveals that the water ways of Port Harcourt in Rivers state were unsafe for travel while the water ways of the Volta Lake were relatively safe as revealed by the average probability ratio of 8:1 in comparative terms. The log linear regression analysis reveals a price elasticity of demand for boat transport of 1.00 and 0.97 for the selected route of Port Harcourt Nigeria and Volta Lake, Ghana respectively. It further supports the fact that more passengers were responsive to travel by waterways in Nigeria than Ghana. The study concludes that waterways of Niger delta basin have high risk indices and likelihood of accident occurrence than the Volta basin; and recommends that VLTC and NIWA should invest optimally and partner with the private sector to enforce and regulate the waterways operations so as to increase safety and mobility of users of the waterways.
