This invention relates to a system and method to generate a private, auditable, evidentiary quality record of the location-history of an asset or person. This invention addresses ten critical improvements over existing systems that are proposed or used for metering for payment services for tolling roads, parking or pay-as-you-drive insurance, namely, cost-effective location accuracy in harsh signal environments, evidentiary assurance of location estimation, handling of dynamic and stationary positioning in a single device, high-ratio compression for a set of stationary positions in urban canyon, high-ratio compression for a dynamic tracklog in urban canyon, high-ratio compression for a set of asset motion behaviors, a method of remote device health check, including anti-tampering, removal of residual price assignment errors, anonymous use without on-board maps, and a method of deconsolidating payments to multiple payees with multiple payment regimes. This system can be applied to road-pricing, congestion-pricing, metered-by-the-minute parking and pay-as-you-drive insurance, incorporating privacy management, and legal admissibility of the evidentiary record. This same device can also be applied to vehicular fleets, military ordinance, or other location audits for assets whether motorized or not, as might be needed in evidence of contract fulfillment or other forms of non-realtime geofencing audits.

Network congestion avoidance within aggregated channels is disclosed. In one embodiment, a method first transmits a packet associated with a first channel of a plurality of related channels from a source protocol layer (e.g., a source IP layer) of a source through a network (e.g., the Internet). Next, the method triggers an ECN event by the packet at the network. Finally, at least one channel is determined to have decreased packets transmitted therethrough, in response to the triggering of the ECN event (e.g., based on a congestion pricing criteria).

The invention discloses a traffic congestion charging strategy optimization method based on VISSIM simulation. The method firstly generates an alternative traffic congestion charging strategy by usinga genetic algorithm, and constructs a topological multi-mode traffic network according to traffic network information, signal light timing information, vehicle information and traffic congestion charging strategy. Then, the traffic flow assignment of the multi-mode traffic network is realized by VISSIM simulation. Finally, the traffic congestion pricing strategy which minimizes the system cost isdetermined by repeated simulation optimization. The optimization method provided by the invention provides the decision basis for the formulation of the traffic congestion charging policy, and effectively alleviates the urban traffic congestion.

Nowadays, the research on congestion pricing and exhaust pollution pricing is very extensive, but the safety pricing to reduce the risk of traffic network is rarely concerned. Therefore, the inventionestablishes a novel two-layer model system. In the upper layer model, the manager minimizes the safety function of the traffic network and designs the charging mode based on it. In the lower model, the behavioral response of travelers to the upper-level pricing will be reflected by a four-stage sequential model with feedback mechanism. In order to solve the above-mentioned two-layer model, the invention is based on the Monte Carlo simulation, a feasible direction method, an iterative weighting method (MSA), a Frank-Wolfe algorithm and a Dijkstra algorithm, and a stochastic feasible directionmethod is designed. Finally, the invention uses a Nguyen-Dupuis network to verify, and the results show that the proposed method and algorithm are feasible and effective. The method of the present invention can be a valuable tool for policymakers who regard traffic safety as a primary policy objective and an evaluation indicator.

A process for increasing profits of a business engaged in the purchase of large numbers of products and / or products of volatile pricing from numerous vendors that operates to identify pricing errors, preferably typically before payment, by automatically reviewing all invoices typically in the order they are received to determine a best system price for each line item of each invoice by reference to pricing factors such as volume discount, seasonal pricing, price protection, commodity pricing, competition pricing, and cash discount recorded in memory for the subject item and reference to payment history data, accounts payable data and invoice data. From the pricing factors and associated data, a best system price is determined and compared to the invoice price for the item so that pricing errors are automatically uncovered and, if appropriate, flagged to identify the same as an exception for warning or notification.

The invention discloses a method for calculating the optimal rate of dynamic congestion charging based on the cellular transmission model. Compared with the existing algorithm, the method for calculating the optimal rate of dynamic congestion charging based on the cellular transmission model is more efficient Fair and effective, the optimal rate obtained minimizes the time consumption of the entire road network; compared with the original cellular transmission model, the path-based cellular transmission model adopted in the present invention has advantages such as no need to calculate cellular waiting time , making the calculation more convenient and efficient, and when the present invention is applied in a larger urban area, it can greatly save the total travel time of the entire road network system.
