Bridge System

Through the investigation of bridges along Shanghai Suzhou Creek, we find a lot of problems. Firstly, Bridge layout is unreasonable. Secondly, mobiles occupy the main traffic volume. Thirdly, slow-traffic and lingering space isn’t comfortable. This study proposes the bridge planning and design idea oriented by slow-traffic and lingering space. Learning from overseas experiences, we put forward the bridge layout suggestions for Suzhou Creek from three aspects. First is to construct the reasonable distance between slow-traffic and lingering bridges. Second is to build the bridge system suitable for fast and slow-traffic. The last is to connect the cross-river attracted sources and bridges. Based on the above, we propose the bridges layout suggestion plan of Suzhou Creek.

The City

It is necessary to construct the slow-traffic and lingering space system of the bridges and both banks in the motorized era. It’s the main part of the city planning for non-motorized travel. Also, it’s important for the development of the cross-river slow-traffic system and the comprehensive development of bridges and both banks. We investigate and analyze the traffic volume, lingering activities and cross-river walking path in the estuary area of Suzhou Creek. And we found three things. Firstly, the cross-river slow-traffic and lingering space is not smooth and attractive. Secondly, the riverside slow-traffic and lingering space is not continuous and extensive. Thirdly, the bridge slow-traffic and lingering space is not safe and comfortable. Based on these, some optimizing strategies are proposed. For example, it is recommended to construct the continuous cross-river slow-traffic network, to establish the both-bank lingering space system around the center of river, and to build bridges with slow-traffic and lingering functions.

Studies on identification of species, fecundity and development stages of blue crab, (Callinectes amnicola) were investigated at the Cross River Estuary between the months of December, 2018 and May, 2019. The parameters used for the study were gonadosomatic and hepatosomatic indices, egg diameter and counts. All measurements followed standard procedures. Gonadosomatic index was at its peak in December (88.9) and April (83.3). This coincided with the peak in egg size suggesting that spawning occurred twice within the period.The low values of hepatosomatic index around December (1.20) and April (0.45) added to confirm the spawning in these months. The species spawns at a mean egg size of 17.55mm. The dimension of crabs examined were in the following range: carapace length 40.0 to 70.0mm, carapace width, 5.0 to 60mm and body weight 40.0 to 140.0g. The relationship between fecundity and weight of crab was  significant (r = 0.295: p<0.05), indicating positive correlation. Absolute fecundity of the species ranged between 1,375 and 225,132 eggs. The smallest crab with egg had a carapace width of 39.5mm and weight of 46.9g. Spawning at this size seems to be a strategy adopted by the species to cope with exploitation pressure. The result of this study revealed that C. amnicola had a high reproductive potentials. Hence, adequate regulation is required to enhance sustainability of the species in the Cross River Estuary.
