基于区块链多链交叉隔离技术的P+R停车场出行技术研究

Research on P+R Parking Travel Technology Based on Blockchain Multi Chain Cross Isolation Technology

当前大中型城市的交通越来越拥堵,政府相关部门出台了相应的措施来解决市民的交通出行问题,但是随着人民生活水平的提高,私家车的保有量越来越高,导致问题越发严重。混合出行方式的出行,为解决私家车保有量高的问题指明了一个方向。混合出行方式中,P+R出行方式是探索的重点方向,其主要是车主开车将车停放至一个离公共交通较近的停车场,然后乘坐公共交通到达单位。其主要的优点在于同时满足了绿色出行与保证出行时效的需求。本文针对P+R出行方式,尝试使用基于区块链的多链交叉隔离技术,建立政府公共交通部门与停车场之间的数据可信交换桥梁。方案主要依托开源的HyperLedger Fabric联盟链框架,创新性的建立多数据独立链,对数据进行分隔、分权访问。在实际的性能测试中,满足了项目的立项要求,其各项性能表现可以满足实际业务需要。

At present, the traffic in large and medium-sized cities is getting more and more congested. The relevant government departments have issued corresponding measures to solve the traffic problems of citizens. However, with the improvement of people’s living standards, the number of private cars is getting higher and higher, resulting in more and more serious problems. The mixed mode of travel has pointed out a plan direction for solving the problem of high private car ownership. Among the mixed travel modes, the P + R travel mode is the key direction of exploration, which mainly refers to the car owner parking his car in a parking lot close to public transport, and then taking public transport to the unit. Its main advantage lies in meeting the requirements of green travel and ensuring travel timeliness. Aiming at the P + R travel mode, this paper attempts to use the Multi chain cross isolation technology based on the blockchain to establish a reliable data exchange bridge between the government public transport department and the parking lot. The scheme mainly relies on the open-source Hyperledger Fabric alliance chain framework to creatively establish a multi data independent chain to separate and decentralize data access. In the actual performance test, the project requirements are met, and its performance can meet the actual business needs.
